your study guide out and you're ready to review let's start this massive review off by examining
the distribution of the human population today we can see that there are four major regions
where people live in fact over two-thirds of the world's population live in these areas there
is South Asia which consists of countries such as India Bangladesh and Sri Lanka East Asia
where we can see countries such as China Japan and Korea southeast Asia which is made up of
several different States including Thailand the Philippines and Vietnam just to name a few these
three regions primarily have people located near rivers and oceans unlike our last region which
is Europe which here people are located closer to Natural Resources instead of clustering solely
around rivers and oceans this can be attributed to the Industrial Revolution which started in Europe
and led to the creation of different industrial cities that were dependent on natural resources
now we can see that the location of human settlements is often influenced by both physical
and human factors of a play physical factors are the natural elements that make up a place such as
the climate weather patterns landforms bodies of water and natural resources historically and today
we can see that most of the major cities around the world are in regions that offer favorable
physical features such as being close to a body of water that facilitates global trade or by being
located near arable land and places with natural resources all of which allow for Industries to
grow and prosper on the other hand human factors refer to various economic cultural historical
and political aspects of a place people often choose to reside in areas that provide a variety
of economic opportunities including access to various jobs and services stable employment
and a wide range of amenities in terms of culture we can see individuals tend to seek Out
locations where they feel accepted can identify with society and feel a sense of community we can
also look at historical events and how they have impacted population distribution for example the
migration of people has been influenced by past trade routes different historical events political
boundaries and former Empires lastly we could look at how political factors impact population
distribution with people often gravitating to areas with a more stable political environment
that offer more protection and maintain a cohesive functioning Society now remember when talking
about population distribution we are talking about the spread of people in an area we can see
that places can be dispersed which means they have their population buildings or other features
spread out or scattered over a wider geographic area instead of being clustered together if
a place is clustered together it means the population buildings or other features in a place
are concentrated in a specific area or region with little to no space between the different features
when looking at population distribution of a place we can also examine the population density of a
play population density is the amount of people in an area and unlike population distribution we
are not focusing on the spread of people instead we are focusing on the number of people when
looking at density we can see that there are three main types of population density that you need
to know arithmetic density physiological density and the agricultural density the arithmetic
density is a commonly used metric to show how crowded a particular area is this density can be
easily calculated regulated by dividing the total number of individuals living in an area by the
total land area of the geographic area a higher arithmetic density indicates that more people are
residing in each unit of land while lower numbers suggest that fewer individuals are living in
each unit of land however it is important to note that the arithmetic density does not account
for the distribution of people within an area it assumes that everyone is evenly spread out
across the area and also does not consider land use patterns that are not intended for residential
living such as agricultural land or uninhabitable land so just because the arithmetic density is
80 does not necessarily mean that there are 80 people living in each unit of land in the area
the next density is the physiological density which measures the pressure that a population
exerts on the environment to feed the population to calculate the physiological density you need
to divide the total number of people in an area by the total amount of arable land notice here
we are not including all of the land for the area instead we are only fact factoring in
arable Lane which is land that can produce food a higher physiological density indicates
that more food needs to be produced from each unit of arable land thereby increasing the
pressure on the environment societies with a high physiological density run the risk of
damaging their arable land by depleting its nutrients which can lead to desertification
this can force societies to rely on importing food from other places rather than producing it
themselves the vinyl density we can examine is the agricultural density which shows the level
of efficiency of agricultural production in an area and the degree of Reliance on human labor
versus technology to calculate the agricultural density we need to divide the number of farmers
in an area by the total amount of arable land a high number indicates more manual labor to
cultivate the crop while lower agricultural density indicates a high degree of mechanization
and more technological advancements resulting in more of the work on the farm being completed
by machines instead of by hand all of which allows for more efficient production to make sure
you're understanding these Concepts take some time and answer the practice problems in your study
guide also if you feel like you need more help with the application of these different densities
head on over to my ultimate review packet after the video where you'll find an exclusive video
helping you practice these Concepts alright so now that we have an understanding of both
population density and distribution let's explore the different consequences of both
of these Concepts politically we can see that areas that have a higher population density often
have greater political power and representation compared to sparsely populated areas with a low
population density population distribution can also impact voting patterns by affecting the
redrawing of voting districts or by creating divisions between urban and rural area in terms
of the economy we can observe that areas with a higher population density usually have more
opportunities for Citizens including a wider range of goods and services and a larger labor
market on the other hand areas that have a lower population density and have more of a dispersed
population often have less access to various amenities and end up relying more on larger
cities for resources and services pairs with a higher population density with their people
living closer together are more likely to have higher taxes and more expensive products compared
to areas with a low population density and a more sparsely populated population which generally have
lower home prices fewer taxes and cheaper goods and service then there are social consequences of
population density and distribution which can vary based on the type of place typically larger and
more densely populated areas have better access to educational and health care services a wider
range of restaurants and more economic and social opportunities for Citizens on the other hand
areas with a lower population density and more of a dispersed population tend to lack specialized
Services as well as various social offers but have more of a community feel lastly we can look at
the impact that density and distribution have on the environment densely populated societies
with more urbanization often see more urban sprawl which results in the placement of green
spaces with buildings and streets on the other hand areas with a dispersed population are
more likely to have more undisturbed areas in green spaces these factors can also affect
a society's carrying capacity which refers to the maximum population size that an environment
can support without damaging it if a population exceeds the carrying capacity of its environment
it may lead to over exploitation of resources depletion of essential nutrients and increase
the chance of desertification and also food shortages all right now that we have explored how
density and distribution can impact a geographic area let's shift our Focus now and delve
into population composition which refers to the various demographic characteristics of
a population including factors like age gender ethnicity educational attainment income and
also occupation by analyzing these different characteristics we can gain insight into the
social economic and cultural factors that shape a society one tool that we can use to better
understand some of these different demographic characteristics is a population pyramid and it's
important that you can not only read a population pyramid but also be able to make inferences
about a society based on the data in a pyramid the y-axis of a population pyramid represents
different age ranges or cohorts which can be found on either the left side or in the middle of
the pyramid depending on the population pyramid's Leia on the x-axis we can see the amount of people
which is either shown as an exact number or is presented as a percent you can also see that the
population pyramid is divided into two sides one representing women and the other representing men
with each bar indicating the number of individuals belonging to a specific age range and set now
we can classify the different age ranges into three main categories based on different stages of
Life the first being pre-reproductive years which consists of individuals who are between the ages
of 0 to 14. the second being reproductive years which consists of individuals who are between the
ages of 15 to 44. and lastly post-reproductive year years which consists of people who are
45 years and above Now population pyramids can provide valuable insights not only into current
trends but also past events and potential future challenges whenever we change the scale of
the population pyramid we can see different aspects of a population National governments can
examine demographic Trends to better understand the rate of Aging their growth rate and potential
challenges for the future for instance a top heavy pyramid indicates an aging population which could
lead to increased Health Care usage declining tax revenue and a decrease in the overall population
population pyramids can be used to gain Insight not only at the national scale but also the
regional and local scale at the regional level population pyramids can provide insight into the
economic potential of a region based on the age distribution of its population regions with
a large percentage of the population in their 20s may have a growing Workforce making them
more attractive to business at the local level population pyramids can help us understand the
dynamic of a community for instance a city with a large percentage of its population in the 20
to 24 age range may be home to different colleges and universities resulting in more of a vibrant
downtown and higher demand for rental property we can also use population pyramids to gain insight
into a country's sex ratio and dependency ratio the sex ratio shows us the ratio of males to
females in a population to find this ratio you take the number of male births in society and
divide it by the number of female births and multiply it by 100. if this ratio is above 100 it
means that there are more male births in society but if it's less than 100 it means there's more
female births in society and if you get a number that's exactly 100 it means the births between
males and females are the same next is the dependency ratio which gives us insight into how
many people a society needs to support the higher the number is the greater the burden there will
be on the working population to find this ratio you take the number of children aged 0 to 14.
and add the amount of people who are 65 years or old and divide by the working age population and
multiply by a hundred now this ratio can also be broken down further into the child dependency
ratio and elderly dependency ratio the child dependency ratio takes the number of people
between ages 0 to 14 and divides by the number of people from ages 15 to 64. then multiplies by
100 while the elderly dependency ratio takes the number of people 65 years and older and devised
by the number of people between the ages of 65 to 64. that multiplies by a hundred never the
last part of this section and for the rest of the questions in your study guide I want you to
practice breaking down these different population pyramids understanding how to read them is one
thing but it's more important that you can connect these pyramids and Concepts to the real world you
do need more help with these pyramids I've created exclusive videos and practice resources that can
only be found in the ultimate review pack in order to help you practice these Concepts even more now
that we have reviewed population composition the time has come to go over population Dynamics
and to start let's review a couple important terms that you need to be familiar with the first
term is the crude birth rate which rep represents the number of live births per 1000 people in a
population within a given year the second term is the crude death rate which represents the number
of deaths per 1000 people in a population within a given year now we can use the CBR and the CDR
to determine our next term which is the natural increase rate also known as the rate of natural
increase to calculate the nir we subtract the CDR from the CBR which will show us a rate of
the population growth or decline in a society this is the percentage by which a population is
changing in a given year due to births and deaths without accounting for migration countries with
a high nir will take less time to double their population which often creates challenges for
countries as they may not be able to keep up with their growing population resulting in a strain
on the country's infrastructure and system the amount of time it takes for a population to
double in size is known as the doubling time countries often will track these growth metrics
to better understand how they need to utilize their resources set policies and predict future
challenges or are opportunities that they might have up next is the total fertility rate which is
the average number of children a woman will have a dfr of 2.1 is considered to be the replacement
rate if a country's TFR Falls below 2.1 the population size will decrease while TFR above 2.1
indicates population growth lastly there is the infant mortality rate which is the total number of
deaths of infants under one year of age per 1000 live birth now we can see that different social
cultural economic and political factors all have a significant impact on the different factors that
we just talked about access to Better Health Care and Educational Services traditionally lead to an
increase in the life expectancy of a society and result in a decrease in the TFR IMR and also
nii if women have more access to education and opportunities in a society we start to see
traditional gender roles be changed which reduces gender inequality in a society societies that
consist of traditional gender roles with rigid systems in place usually have a higher TFR and
Nia as women have fewer opportunities outside of the home more economically developed areas often
have higher rates of urbanization with more jobs opened up in the tertiary sector instead of the
primary and secondary sector which is one of the reasons why these societies often see smaller
family sizes as children are no longer viewed as economic assets and individuals prioritize
their career on the other hand areas that are less economically developed tend to have
economies that are agricultural based with a greater concentration of jobs in the primary and
secondary sector this often leads to larger family sizes as individuals require more assistance on
their farms and in their home finally the impact of political policies on population growth
can also be seen in a society we can see that governments have the power to implement laws
and use propaganda to encourage Family Planning promote the use of contraceptives and enhance
access to education for everyone all of which would decrease the population growth rate of a
society however if a government restricts access to contraceptives fails to provide adequate
education on Family Planning and denies women their rights the result may be an increase in the
population's growth rate the time has come to go over the demographic transition model which
is arguably one of the most important models in this course the first stage of the model is
characterized by a high CBR and CDR resulting in a low nir in this stage the majority of the
population is engaged in subsistence agriculture where people produce food primarily for their
own consumption rather than for sale women in this stage typically have limited opportunities
in society and lack access to education with their roles primarily being focused on household tasks
and childbearing migration during this stage is often seasonal as people migrate in search of
food Societies in this stage also lack access to Medicine contraceptives and medical knowledge
resulting in high mortality rates which can come from almost really anything now today there no
longer are any countries in stage one as they've all moved further along the demographic transition
model now after the Industrial Revolution many countries begin transitioning from stage 1 to
Stage 2 of the demographic transition model countries in stage two continue to have a high CBR
however their CDR starts to decrease resulting in a significant increase in their nir all of which
causes a population boom countries in stage two start to see their IMR and CDR decrease thanks to
advancements in technology increased agricultural production better sanitation and increased
knowledge in medicine during stage two women start to see slight expansions of their role
which allows them to occasionally participate in the formal economy however women's access
to education remains limited and they continue to serve as primarily caregivers in their home
countries also observe changes in their migration pattern with more individuals leaving rural
areas and relocating to Urban region all which happens as people continue to search for more
economic opportunities located in urban areas and due to changes in agricultural production as
production now is transitioning from subsistence agriculture over to commercial today we can also
see increased rates of emigration Mission as well as more migrants seek economic opportunities in
core countries and more economically developed areas we're looking at the world today we
can see countries like Afghanistan are in stage two of the demographic transition model
as seen here in their population pyramid notice that the majority of their population is in
the pre-reproductive years and reproductive years which shows a country with an expanding
population now as countries progress into stage three we can start to see their CBR Decline and
their CDR continues to decrease as well all of which makes their nir more moderate part of which
is due to improved medical technology which leads to a higher life expectancy and a reduction in
the infant mortality rate ultimately resulting in smaller family size urban areas also start
to become more dominant economic centers in the state with jobs focusing and Manufacturing as
more people continue to migrate from rural areas to urban areas we start to see people have fewer
children due to a lack of space and also due to economic changes during stage three women also
start to gain greater access to Education Health Care and economic opportunities which contribute
to the declining CBR and nir the society continues to advance economically we start to see a rise in
job opportunities in the secondary sector of the economy along with also growth happening in the
tertiary sector as more economic opportunities open up in the country we also start to see shifts
in the amount of migrants who are emigrating from the country as more people continue to migrate
to urban areas for economic opportunities today we can look at Mexico as an example of a stage
three country notice when looking at Mexico's population pyramid the middle of the pyramid
is starting to fill out more people in the country are now in their reproductive years and
post-reproductive years we can see that Mexico is still growing as a country but not as fast as
it would have been if it was in stage two moving on to stage four we can see countries that have a
low CBR low CDR and also a low to Flat nir during this stage countries may experience zpg which
stands for zero population growth this happens when a CBR and a CDR are essentially the same
causing the nir to be zero during stage four we can see women play an active role in society and
the economy with greater access to education being able to pursue careers and more control over their
reproductive choices countries in stage four also have access to specialized medicine and doctor as
well as a robust Health Care System we also can see migration patterns start to shift as urban
areas start to experience counter urbanization as more people start to move into the suburbs
additionally countries in stage four witnessed increased immigration from less economically
developed States as more individuals seek economic opportunities in the country today we
can see countries like the United States and China are good examples of a stage four country
we look at their population pyramids we can see they form more of a box shape notice that the
population is spread out between the different age cohorts and while the countries are no longer
seeing a large population growth they are also not seeing a large decline finally there is the
speculative stage five is characterized by a low CBR a low CDR and a negative Nar in this stage the
country's births fall below their debt resulting in a decline in the population countries that
could be in stage five would be Japan or Germany notice how the majority of their population is
located in the post-reproductive years on their population pyramid both of these countries have a
negative Nar which means their overall population is decreasing it's also important to note that
migration can impact these Trends and when discussing CBR CDR and Nar we are only looking
at births and deaths that occur within a country immigration is not factored into these metrics
the last part of this section is the epidemiologic transition model which focuses on the causes of
death for each stage of the demographic transition stage one is characterized by high mortality
rates from pestilence famine and other causes people are vulnerable to a range of diseases
including parasitic and infectious diseases animal attacks pandemics epidemics food shortages
and contaminated water sources just to name a few essentially if you can name it you can die from it
one of the most well-known killers in this stage was the Bubonic plague stage two is categorized
by fewer deaths and a reduction in pandemic during this stage Society gains access to new technology
that not only improve the standard of living but also increase the amount of food that is produced
people start to see an increase in their caloric intake and there is an improvement in the
sanitation as societies continue to progress they eventually reach stage three which is
characterized by an increase in degenerative diseases during this stage people start to
live longer and begin to die from diseases that are either caused by human behavior or are
related to age examples include heart disease from eating unhealthy foods and various types of
cancer next to stage four which is categorized by fighting degenerative diseases and overall
longer life expectancy your medical advancements can often delay the onset of different diseases
leading to increased life expectancy during this stage people generally continue to improve their
diets and make better health decisions such as by avoiding drug use however advancements in society
can also lead to negative eating habits such as the consumption of junk food and a sedentary
lifestyle which can contribute to new health problems like obesity and diabetes the fifth and
final stage is characterized by the Resurgence of infectious diseases including parasitic and
infectious diseases that become more prevalent again this can occur due to the evolution of
different diseases which can lead to mutations and the development of antibiotic resistance
another reason is the increase in poverty and urbanization as densely populated areas make it
easier for diseases to spread while at the same time we can see that people living in poverty
often have limited access to health care which can result in a higher CDI lastly globalization
and the ease of travel can also contribute to the spread of pandemic such as the covid-19 pandem as
people share ideas and germs across the world now one thing I want to Quick point out is the first
four stages of the demographic transition model pair pretty well with the first four stages of the
epidemiologic transition model however the fifth stage age does not connect moving into the next
part of the unit we have malthusian Theory Malthus was an English Economist who lived in England
during the Industrial Revolution when England was in stage two of the demographic transition
Malthus became concerned over the population growth of society he argued that while society's
population would continue to grow exponentially its ability to produce food would only increase at
an arithmetic rate this would eventually lead to a malthusian catastrophe in which the population
would surpass the carrying capacity resulting in famine War disease outbreaks and the collapse
of society to stop this Malthus believed that an intervention was necessary to prevent uncontrolled
population growth for example governments could start implementing anti-natalist policies that
would motivate people to have less kids how this was criticized during his time his ideas of
smaller family sizes came out during a time where people had larger families ultimately
we can see malfoots turned out to be wrong as countries develop economically their growth
rates start to slow resulting in their popular relation rate no longer being exponential and due
to the agricultural revolutions and advancements in farming technology we can also see food
production increase at a faster rate than what Malthus predicted nevertheless there are still
people out there who believe in mouth they are known as Neil malthusians and they believe that
the world supply of Natural Resources will deplete as population continues to grow malthusians have
expanded on maltus's original idea to not just include food but resources in general essentially
the world has a finite supply of natural resources and as our population continues to grow we will
continue to deplete those resources an example of a Neo malthusian would be Thanos who believed
that killing half of the world's population was the solution to this problem all right geographers
you're over halfway done with unit 2 and I know it's a long one but you're doing great make sure
you keep following along with that study guide and if you need to you know take a little stretch
break stretch it out all right now we're going to be moving into 2.7 though where we're going to
be talking about governments and their ability to influence population we can see that governments
have the power to influence demographic Trends and migration patterns all by using various
tools we can divide government policies that impact population growth into two categories
pronatalist policies are designed to encourage people to have more children and larger families
these policies often involve propaganda tax incentives for families with children resources
for Family Planning and the removal of economic or political barriers for families these policies
are typically implemented in a country with a low or negative Nia on the other hand we also have
countries that have a high nir where we can see the implementation of anti-natalist policies which
seek to reduce the amount of births in a society for example China's one child policy which set
limits on the amount of children individuals can have this was a controversial law and was put in
place to prevent overpopulation from occurring now I do want to note that recently China has doubled
back on this policy and started to modify this is because this policy was so effective at limiting
family size that China's population growth fell on almost too much in addition to population policies
migration policies can also impact as society's growth governments often base their immigration
policies on their economic needs National Security priorities and cultural value when immigrants
are allowed into a country it tends to increase the economic output of the country increase the
amount of diversity in the country and can lead to new inventions and ideas for society all right now
comes the time to talk about women and demographic changes as economies develop opportunities for
women tend to increase in economically developed countries women have greater access to Quality
education participate more in the workforce have better access to health care and have more control
over their reproductive Choice with increased education women tend to delay having children
resulting in a lower total fertility rate and infant mortality rate this is because as women get
educated they end up spending more time in school and in the workflow leading to fewer children
being born on average additionally as both men and women gain education they learn more about
how to keep children safe safe healthy and happy resulting in a lower IMR this increase in Economic
Development and opportunities for women also leads to a decrease in the maternal mortality rate which
is the annual number of female deaths per 100 000 live births from any cause related to
pregnancy in countries with greater gender inequality women tend to have fewer opportunities
less access to education legal protection and are often limited to traditional gender roles as
caretakers which often results in these countries tending to have higher TFR countries that offer
women less opportunities and protections tend to be countries with less economic development we
can see that Economic Development and greater opportunities for women not only change the birth
and growth rate of a country but can also change migration patterns as well to understand migration
patterns we can look at ravenstein's laws of migration's laws of migration provide insight into
migration patterns but it should be noted that some of these have started to change in recent
years due to different political cultural and economic shifts in society haven't seen observed
that most migration happens for economic reasons and is often undertaken by young adults this
is because young adults have fewer ties to a specific geographic area that are more flexible to
take advantage of economic opportunities in other places ravenstein also noted that migrants often
travel short distances and will travel in Step migration which ties into our next law which is
that migrants are more likely to move from a rural area to an urban area as migrants travel towards
their final destination they tend to settle in different towns and cities before reaching
a larger urban area the farther the migrant is traveling the more likely it is that they are
migrating to a larger urban area this pattern is also observed in the gravity model which helps
to explain migration flows between different Geographic locations the gravity model is based on
the assumption that migration flows are influenced by the population size and distance between the
migrants origin and destination notice here even though City 2 and City 3 are closer together both
are more likely to migrate and interact with City one ravenstein also noted that whenever migration
happens a counter stream would be created this means that when a person migrates to a new
place they connect their original location with the new location the next law stated that
large urban areas tend to experience population growth primarily through migration rather than
by natural birth now Robinson also observed that migration can lead to increased development as it
often brings new Goods Foods ideas and businesses with it lastly ravenstein noted that women are
more likely to migrate internally within a country while young males are most likely to migrate
International this was because traditionally men were the only ones who had access to more
wealth and were seen as the provider of the family however in recent years we have started to
see this change as more women enter the workforce and gain Financial Freedom right now we've
talked about changes in Economic Development and also birth rates but we also need to talk
about what happens when a population starts to Aid as countries experience Economic Development
their populations tend to eight leading to new challenge one major challenge is the increase
in the dependency ratio when more people start to retire putting a greater burden on the working
population a higher dependency ratio means less people are working and paying into the system
while at the same time as people retire we can see more people starting to access their retirement
funds and need more Health Care Services resulting in more money being taken out of the system this
shift in demographics may lead to a reduction in economic growth as countries raise taxes to
support their aging populations health care and retirement needs aging societies may also see
shifts in family structures with family members taking on the responsibility of providing care
for their elderly relatives countries with an older population Also may experience a decrease
in their growth as a majority of citizens are now in their post-reproductive years resulting
in shortages of workers to support the economy now to try and combat some of these Trends some
countries may start to implement pronatalist policies to boost their nir and reduce their
overall dependency Ratio or we can countries Implement more pro-immigrant policies to try
and attract a new Workforce by now changing gears and moving into migration we can see that
people migrate for a variety of different reasons when looking at migration we can see different
push and pull factors whole factors refer to the positive conditions events and factors that
attract people to a particular geographic location while on the other hand push factors refer to
the negative conditions events and factors that motivate people to leave their current Geographic
locations every place has different economic political social and environmental push and pull
factor economic push factors for example could include a lack of job opportunities in a person's
Home Country economic instability high taxes or a higher cost of living all economic pull factors
could be more business opportunities less taxes or greater variety of goods and services political
push factors may include political persecution discrimination lack of political Freedom or an
unstable political environment while political whole factors may include better access to
government services protection of individual right political Freedom or political stability social
push factors may include religious or cultural persecution rampant discrimination or a lack of
social services such as health care or education on the other hand social pull factors may include
positive situations like access to Quality Health Care increased access to education acceptance of
different cultures or desired to be close to other family members lastly environmental push factors
may include negative situations like natural disaster environmental degradation increased
air and water pollution or undesirable climate while environmental pull factors may include
favorable climates better living conditions with less pollution or more access to arable land and
natural resources now if a person is moving out of a place it is known as emigration and if a person
is moving into a place it's known as immigration to make sure you don't mix these terms up think
of immigration as e for exit and immigration as I for in two other Concepts that you will want
to be familiar with when it comes to migration is intervening obstacles and intervening opportunity
intervening obstacles are negative situations or events that hinder migration and end up preventing
migrants from reaching their final destination for example if a migrant ran out of money to complete
their migration or are denied entry to an area due to immigration policy while intervening
opportunities on the other hand are positive situations or events that hinder migration and end
up preventing migrants from reaching their final destination for example if you're on your way
to your destination but find a job offer in an area you were driving through and decide to take
the job now when it comes to migration we can see that migration can either be forced or voluntary
let's start by reviewing Force migration which is when the migrant has no choice but to migrate
human trafficking Force child labor child soldiers slavery are all examples of force migration Force
migration happens when individuals are compelled to leave their country due to reason such such as
War political oppression or environmental disaster migrants who have been forced to leave their home
country and have crossed an international border in order to escape War persecution or natural
disasters are known as refugees oftentimes refugees May seek asylum in another country
if a migrant does not cross an international boundary then they would not be classified as
a refugee I would instead be classified as an internally displaced person idps have been forced
to flee their home in order to protect themselves and their family just like a refugee but they
have not crossed an internationally recognized State boundary so they remain in their home
country now unlike Force migration voluntary migration happens because people are choosing
to leave their current location on their own free will transnational migration occurs when
people choose to leave their country of origin and seek residents in a different state typically
transnational migrants maintain ties to their home country and settle in areas with similar cultural
value chain migration is a type of migration that is part of of a country's family reunification
policy this type of migration is a process in which legal immigrants who have become naturalized
citizens sponsor a family member to immigrate to the country that migration refers to migration
that occurs in stages where migrants make stops at different locations before reaching their
final destination oftentimes we can see migrants who are migrating by step migration be impacted by
intervening opportunities or intervening obstacles which may prevent them from getting to their
final destination now sometimes migrants may temporarily migrate to a new country for work or
for educational reasons these migrants are known as guest workers oftentimes these migrants
may send money back to their home country which is known as the next type of migration is
transhumans migration this migration is cyclical meaning that it occurs in regular intervals or
patterns transhumans migration revolves around the seasonal movement of livestock between two
different locations livestock has led to Highland areas in the summer months and lowland areas
in the a winter months then there is Rule to Urban migration which is the movement of people
from rural areas to urban areas this most often occurs because people are seeking more economic
opportunities in the larger urban areas lastly you also want to be familiar with both intra
Regional migration and Inter Regional migration two terms that honestly are really easy to mix up
intra-regional migration refers to the movement of people within a particular region for example
a person moving from an urban area to a suburban area while inter-regional migration refers to the
movement of people between different regions for example if I moved from the Midwest to the United
States down to the southeast of the United States just remember intra Regional migration is the
movement of people within the same region while inter Regional migration is migration from one
region to another and this is also a great reason why you need to take your time on your unit
to test or the AP National exam you always want to read every question very carefully you
skim questions or answers you're more likely to miss small details I could cost you points if
you need more help with the different types of migration and causes of migration you can find
more exclusive resources and videos inside my ultimate review pack I run to the last part of
unit 2 and it's important now that we examine the impact a migration can have on a region the
political ramifications of migration can be seen in everyday conversations and media discussions
as Citizens debate issues such as citizenship for migrants which immigration policy should be
priority we can see that individuals who wish to reduce the number of immigrants entering
a country May support immigration quotas that limit the number of immigrants emitted in a year
on the other hand those who want to increase the number of immigrants May endorse policies such as
family reunification or Diversity Lottery programs which allow individuals from specific countries
worldwide to enter a country economically we can see increased immigration often leads to
increased Talent pools as societies gain new skills knowledge and expertise from their new
migrants all of which leads to more economic output for a country on the other hand countries
that do not have as much to offer their citizens might experience brain drain which is when
skilled labor leaves a geographic area in favor of another area that offers more opportunity
culturally migration leads to the mixing of different Traditions languages and value leading
to acculturation assimilation or syncretism as more migrants enter the country we often see the
cultural diversity of the country increase but at the same time we also may see anti-immigrant
or Refugee sentiment develop this often happens when individuals are worried about losing certain
aspects of their life culture or unique cultural landscape our geographers you have done it we
are done with unit two now comes the time to check your answers to the study guide and also
practice what we have learned in order to make sure that you are ready for your unit test head
