ZIP Code Tabulation Area
ZIP Code Tabulation Areas (ZCTAs) are statistical entities developed by the United States Census Bureau for tabulating summary statistics. These were introduced with the Census 2000 and continued with the 2010 Census and 5 year American Community Survey datasets. They were updated again for the 2020 census. This new entity was developed to overcome the difficulties in precisely defining the land area covered by each ZIP code. Defining the extent of an area is necessary in order to tabulate census data for that area. ZCTAs are generalized area representations of the United States Postal Service (USPS) ZIP code service areas, but are not the same as ZIP codes. Individual USPS ZIP codes can cross state, place, county, census tract, census block group and census block boundaries, so the Census Bureau asserts that "there is no correlation between ZIP codes and Census Bureau geography". Moreover, the USPS frequently realigns, merges, or splits ZIP codes to meet changing needs. These c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Census Tract
A census tract, census area, census district or meshblock is a geographic region defined for the purpose of taking a census. Sometimes these coincide with the limits of cities, towns or other administrative areas and several tracts commonly exist within a county. In unincorporated areas of the United States these are often arbitrary, except for coinciding with political lines. Census tracts represent the smallest territorial entity for which population data are available in many countries. In the United States, census tracts are subdivided into block groups and census blocks. In Canada, they are divided into dissemination areas. In the U.S., census tracts are "designed to be relatively homogeneous units with respect to population characteristics, economic status, and living conditions" and "average about 4,000 inhabitants". By country Brazil The Brazilian Institute of Geography and Statistics uses the term census sector (''setor censitário''). As of the 2022 Census, there ...

Census Block Group
A Census Block Group is a geographical unit used by the United States Census Bureau which is between the Census Tract and the Census Block. It is the smallest geographical unit for which the bureau publishes sample data, i.e. data which is only collected from a fraction of all households. Typically, Block Groups have a population of 600 to 3,000 people. Every Census Block Group has a unique 12-digit FIPS code. The Block Group's unique identifier is the 12th digit of the FIPS Code. This number determines the first digit of all the census blocks contained within a block group. For instance, census Block Group 2 includes any block numbered 2000 to 2999. For the 2000 US Census, the United States including Puerto Rico had 211,267 block groups, each containing an average of 39 blocks. For the 2010 US Census, the United States (not including Puerto Rico, United States Virgin Islands The United States Virgin Islands, officially the Virgin Islands of the United States, are a group o ...

Census Block
A census block is the smallest geographic unit used by the United States Census Bureau for tabulation of 100-percent data (data collected from all houses, rather than a sample of houses). The number of blocks in the United States, including Puerto Rico ; abbreviated PR), officially the Commonwealth of Puerto Rico, is a Government of Puerto Rico, self-governing Caribbean Geography of Puerto Rico, archipelago and island organized as an Territories of the United States, unincorporated territo ... and other island areas, for the 2020 Census was 8,180,866. Census blocks are grouped into block groups, which are grouped into census tracts. There are on average about 39 blocks per block group. Blocks typically have a four-digit number; the first number indicates which block group the block is in. For example, census block 3019 would be in block group 3. Blocks are typically bounded by roads and highways, town/city/county/state boundaries, creeks and rivers, etc. In cities, a cens ...

Topologically Integrated Geographic Encoding And Referencing
Topologically Integrated Geographic Encoding and Referencing, or TIGER, or TIGER/Line is a format used by the United States Census Bureau to describe physical and cultural features such as roads, highways, city limits, rivers, and lakes, as well as areas such as census tracts. TIGER was developed to support and improve the Bureau's process of taking the Decennial Census. The TIGER files do not contain the census demographic data, but merely the geospatial/map data. GIS can be used to merge census demographics or other data sources with the TIGER files to create maps and conduct analysis. TIGER data is available without cost because U.S. Government publications are required to be released into the public domain. Coverage The TIGER/Line shapefile data includes complete coverage of the contiguous United States, Alaska, Hawaii, Puerto Rico, the U.S. Virgin Islands, American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, and the Midway Islands. TIGER includes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Address (geography)
An address is a collection of information, presented in a mostly fixed format, used to give the location of a building, apartment, or other structure or a plot of land, generally using political boundaries and street names as references, along with other identifiers such as house or apartment numbers and organization name. Some addresses also contain special codes, such as a postal code, to make identification easier and aid in the routing of mail. Addresses provide a means of physically locating a building. They are used in identifying buildings as the end points of a postal system and as parameters in statistics collection, especially in census-taking and the insurance industry. Address formats are different in different places, and unlike latitude and longitude coordinates, there is no simple mapping from an address to a location. History Until the 18th and 19th centuries, most houses and buildings were not numbered. In London, one of the first recorded instances of a ...

Post Office Box
A post office box (commonly abbreviated as P.O. box, or also known as a postal box) is a uniquely addressable lockable box located on the premises of a post office. In some regions, particularly in Africa, there is no door-to-door delivery of mail; for example, in Kenya. Consequently, renting a PO box has traditionally been the only way to receive mail in such countries. Generally, post office boxes are rented from the post office either by individuals or by businesses on a basis ranging from monthly to annual, and the cost of rent varies depending on the box size. Central business district (CBD) PO boxes are usually more expensive than rural PO boxes. In the United States, the rental rate used to be uniform across the country. Now, however, a postal facility can be in any of seven fee groups by location; in addition, certain customers qualify for free box rental, usually because the Postal Service does not offer carrier-route delivery to their physical addresses. In the U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Census-designated Place
A census-designated place (CDP) is a Place (United States Census Bureau), concentration of population defined by the United States Census Bureau for statistical purposes only. CDPs have been used in each decennial census since 1980 as the counterparts of incorporated places, such as self-governing city (United States), cities, town (United States), towns, and village (United States), villages, for the purposes of gathering and correlating statistical data. CDPs are populated areas that generally include one officially designated but currently unincorporated area, unincorporated community, for which the CDP is named, plus surrounding inhabited countryside of varying dimensions and, occasionally, other, smaller unincorporated communities as well. CDPs include small rural communities, Edge city, edge cities, colonia (United States), colonias located along the Mexico–United States border, and unincorporated resort and retirement community, retirement communities and their environs. ...
