National Census 2025. Basic definitions. Index. In this module we will cover the following topics. One, basic definitions. Two, reinforcing knowledge. Basic definitions. One. Salted apples. It is the physical area delimited by pedestrian and/or vehicular traffic routes or by natural and/or artificial elements. A sensory block can contain housing, a park, a market, among others. The block numbering is unique and can be alphanumeric in a sensory area. [Music] Sensal blocks, depending on their shape, can be blocks with scattered dwellings, a bag of dwellings. These types of blocks are, in most cases, located on the outskirts of the urban area. Since there is no defined shape, the houses are grouped according to the access roads to them. Irregular, non-angular apples with curved fronts. This type of block can often be found in undeveloped areas of cities. Their irregular shape may correspond to the fact that they maintain curves due to height differences, edges that correspond to roads that may or may not be passable, that surround rivers, ravines, among others. Regular, angular polygonal blocks . They are the most common blocks in the consolidated area of cities. They can have three or more sides forming polygons. In addition, they are easy to recognize. As an exception, you can find apples with only one oval front. Blocks that have one or more fronts that are not passable because they border on natural and/or artificial elements. Multi-family housing blocks will be displayed on the sketch as a sensuous block. Two. Front of the sensory block. It is the side or part of the block that borders a pedestrian or vehicular traffic route or any natural or artificial element. Each front of the sensory block is numbered from one to n, with the starting point being front number one, which corresponds to the northwest corner. From that point and in a clockwise direction, the fronts continue to be numbered until they culminate and end at the corner of the initial point. Three. Census tract corresponds to the geographical area of one or more political-administrative districts or to the part of a district. It comprises the grouping of contiguous sensory sections. A sensory sector is in charge of a sensory sector supervisor. The Sensal sector supervisor is in charge of 12 Sensal section heads and 48 Sensicists on average. Four. Urban sensual section. It corresponds to the geographical area of one or more sensory blocks and includes the grouping of contiguous atus. The urban sensory section is headed by a sensory section chief. The head of the sensal section is in charge of four senscists. Five. Urban work area ATU is the grouping of one or more blocks in salts that on average total 120 homes. The ATU corresponds to the workload of a sensista in the urban area. The ATU will be worked on by a sensista over a 14-day work period. Six. Rural census section is the grouping of 240 rural dwellings on average that may belong to one or more population centers. The rural sensal section corresponds to the workload of four sensistas and will be worked on over a period of 14 days. Seven. ATR rural work area. It is a grouping of 60 rural dwellings on average that may belong to one or more population centers or separate from one. The ATR corresponds to the workload of a sensista. It will be worked on over a period of 14 days. Reinforcing knowledge. Let's get started. They are the most common blocks in the consolidated area of cities. They can have three or more sides forming polygons and are easy to recognize. The concept corresponds to selecting the correct alternative. [Music] Right? The answer is regular apple. What does the acronym ATR stand for and how many homes does it have on average? Select the correct alternative. [Music] Perfect. The answer is that the rural work area has 60 homes on average. Excellent. Have you completed this module? [Music]
