AP Human Geography Unit 2 Review

Introduction

  • Purpose: Review of Unit 2 for AP Human Geography
  • Resources: Study guide from Ultimate Review Packet
  • Contents of Packet: Unit review videos, practice quizzes, study guides, answer keys, full practice AP exams, FRQ resources, vocab lists, exclusive videos

Human Population Distribution

  • Major Regions:
    • South Asia: India, Bangladesh, Sri Lanka
    • East Asia: China, Japan, Korea
    • Southeast Asia: Thailand, Philippines, Vietnam
    • Europe: Influenced by the Industrial Revolution
  • Influences on Settlement Locations:
    • Physical Factors: Climate, landforms, water bodies, resources
    • Human Factors: Economic opportunities, cultural/historical context, political stability

Population Distribution and Density

  • Population Distribution: Spread of people in an area (dispersed vs. clustered)
  • Population Density: Number of people per area
    • Arithmetic Density: Total population / total land area
    • Physiological Density: Total population / arable land
    • Agricultural Density: Farmers / arable land

Consequences of Population Distribution and Density

  • Political: Greater political power and representation in dense areas
  • Economic: More job opportunities and services in dense areas
  • Social: Better access to services in dense areas, community feel in dispersed areas
  • Environmental: Urban sprawl vs. green spaces, carrying capacity concerns

Population Composition

  • Demographic Characteristics: Age, gender, ethnicity, etc.
  • Population Pyramids:
    • Age Categories: Pre-reproductive (0-14), Reproductive (15-44), Post-reproductive (45+)
    • Insights: Aging population, economic potential, local community dynamics
  • Ratios:
    • Sex Ratio: Males to females in a population
    • Dependency Ratio: Non-working age population / working age population

Population Dynamics

  • Crude Birth Rate (CBR): Live births per 1000 people
  • Crude Death Rate (CDR): Deaths per 1000 people
  • Natural Increase Rate (NIR): CBR - CDR
  • Total Fertility Rate (TFR): Average children per woman
  • Infant Mortality Rate (IMR): Infant deaths per 1000 live births
  • Factors Influencing Dynamics: Health care, education, economic development, political policies

Demographic Transition Model

  • Stage 1: High CBR & CDR, low NIR
  • Stage 2: High CBR, declining CDR, high NIR
  • Stage 3: Declining CBR, low CDR, moderate NIR
  • Stage 4: Low CBR & CDR, low/zero NIR
  • Stage 5: Speculative, declining population

Epidemiologic Transition Model

  • Stage 1: High mortality from disease and famine
  • Stage 2: Decrease in pandemics, improved living standards
  • Stage 3: Degenerative diseases
  • Stage 4: Fight against degenerative diseases
  • Stage 5: Resurgence of infectious diseases

Malthusian Theory

  • Concerns: Population growth exceeding food production
  • Neo-Malthusians: Concerns over depletion of resources

Government Influence on Population

  • Pronatalist Policies: Encourage larger families
  • Antinatalist Policies: Reduce birth rates

Women's Role in Demographic Changes

  • Economic Development: Increased opportunities for women
  • Impact: Lower TFR, IMR, maternal mortality

Migration

  • Ravenstein's Laws: Economic reasons, short distances, step migration
  • Migration Types: Forced vs. voluntary, transnational, chain, step, guest workers, transhumance, rural to urban, intraregional, interregional
  • Push/Pull Factors: Economic, political, social, environmental
  • Intervening Obstacles/Opportunities: Hindrances and opportunities affecting migration

Impact of Migration

  • Political: Citizenship debates, immigration policies
  • Economic: Talent pool, brain drain
  • Cultural: Acculturation, assimilation, syncretism

These notes provide a comprehensive overview of the key concepts covered in Unit 2 of AP Human Geography, focusing on population distribution, density, dynamics, the demographic transition model, and migration. Make sure to practice and understand these concepts for a thorough preparation.
