County Subdivisions are the primary divisions of counties and equivalent entities. They include census county divisions, census subareas, minor civil divisions, and unorganized territories, and can be classified as either legal or statistical. Legal entities are termed minor civil divisions and statistical entities can be either census county divisions, census subareas, or unorganized territories.

Minor Civil Divisions (MCDs) are the primary governmental or administrative divisions of a county in many states (parishes in Louisiana) and of the county equivalents in Puerto Rico and the Island Areas. MCDs in the United States, Puerto Rico, and the Island Areas represent many different kinds of legal entities with a wide variety of governmental and/or administrative functions. MCDs include areas variously designated as barrios, barrios-pueblo, boroughs, charter townships, commissioner districts, election districts, election precincts, gores, grants, locations, magisterial districts, parish governing authority districts, plantations, purchases, reservations, supervisor's districts, towns, and townships. The Census Bureau recognizes MCDs in 29 states, Puerto Rico, and the Island Areas. The District of Columbia has no primary divisions, and is considered equivalent to an MCD for statistical purposes.

In some states, all or some incorporated places are not part of any MCD; these places are termed independent places. In nine states-Maine, Massachusetts, New Hampshire, New Jersey, North Dakota, Pennsylvania, Rhode Island, South Dakota, and Wisconsin-all incorporated places are independent places. In other states, incorporated places are part of, or dependent within, the MCDs in which they are located, or the pattern is mixed-some incorporated places are independent of MCDs and others are included within one or more MCDs.

In New York and Maine, American Indian reservations (AIRs) generally exist outside the jurisdiction of any town (MCD) and thus also serve as the equivalent of MCDs for purposes of data presentation.

In states with legal MCDs, the Census Bureau assigns a default FIPS county subdivision code of 00000 and ANSI code of eight zeroes in some coastal, territorial sea, and Great Lakes water where county subdivisions do not extend into the Great Lakes or out to the three-mile limit.

Census County Divisions (CCDs) are areas delineated by the Census Bureau in cooperation with state, tribal, and local officials for statistical purposes. CCDs have no legal function and are not governmental units. CCD boundaries usually follow visible features and usually coincide with census tract boundaries. The name of each CCD is based on a place, county, or well-known local name that identifies its location.

Census Subareas are statistical subdivisions of boroughs, city and boroughs, municipalities, and census areas, the statistical equivalent entities for counties in Alaska. The state of Alaska and the Census Bureau cooperatively delineate the census subareas to serve as the statistical equivalents of MCDs.

Unorganized Territories (UTs) are defined by the Census Bureau in nine MCD states where portions of counties or equivalent entities are not included in any legally established MCD or incorporated place. The Census Bureau recognizes such separate pieces of territory as one or more separate county subdivisions for census purposes. It assigns each unorganized territory a descriptive name, followed by the designation "UT".

Contained within the 5th Edition (1978 to 1995) of the National Atlas of Canada is a map that shows the boundaries and names of all Census Divisions and non-urban Census Subdivisions (for example, townships). Three inset maps are used for areas with dense coverage of Census Subdivisions. A large table lists all entries on the maps.

Census Regions are groupings of states and the District of Columbia that subdivide the United States for the presentation of census data. There are four census regions-Northeast, Midwest, South, and West. Each of the four census regions is divided into two or more census divisions. Puerto Rico and the Island Areas are not part of any census region or census division.

The boundary files portray the geographic limits used for census dissemination. They are available for download in two types: cartographic and digital. Cartographic boundary files depict the geographic areas using only the shorelines of the major land mass of Canada and its coastal islands. Digital boundary files depict the full extent of the geographic areas, including the coastal water area. The files provide a framework for mapping and spatial analysis using commercially available geographic information systems (GIS) or other mapping software.

A population ecumene is the area of inhabited lands or settled areas generally delimited by a minimum population density. This ecumene shows the areas of the densest and most extended population within census divisions. Census divisions are the provincially legislated areas (such as county, municipalité régionale de comté, and regional district) or their equivalents. Census divisions are intermediate geographic areas between the province or territory level and the municipality (census subdivision). For further information, consult the Statistics Canada’s 2016 Illustrated Glossary (see below under Data Resources). The assemblage of dissemination area population density data from the 2016 Census of Population are used to form the ecumene within census divisions. Areas included in the ecumene are dissemination areas where the population density is greater than or equal to 0.4 persons per square kilometre or about one person per square mile. In some areas to capture more population within the ecumene the criteria was extended to 0.2 persons per square kilometre. The ecumene areas were generalized in certain areas to enhance the size of some isolated ecumene areas in northern Canada. This map can be used as an “ecumene” overlay to differentiate the sparsely populated areas from the ecumene in conjunction with census division data or other small-scale maps. This ecumene shows a more meaningful distribution of the population for Canada.

Contained within the 4th Edition (1974) of the Atlas of Canada is a set of three maps. The main map shows the location and extent of census divisions as of 1961. The second map shows the same information for the most populous regions of Ontario and Quebec at a larger scale of 1:5 000 000. These two maps are accompanied by a textual index that references the coding system used to identify the census divisions to corresponding place names. The third map shows Yukon Territory and Northwest Territories and is accompanied by a supplementary text explaining how these areas are treated as census divisions.

Contained within the 3rd Edition (1957) of the Atlas of Canada is a main map that shows fifteen condensed maps of geostatistical units used by the 1951 Census. The main map shows the census divisions as used in that census to gather, compile and publish many of the results of the censuses of Canada. Census divisions normally correspond to counties, but the Dominion Bureau of Statistics (which is now Statistics Canada) had to create equivalent units for counties in each of Newfoundland, Manitoba, Saskatchewan, Alberta and British Columbia. The main map has a table listing all of the census divisions. Around the main map are individual maps for each of the 15 census metropolitan areas as used in the 1951 Census. Each of these small maps shows the component municipalities in the metropolitan area and also shows the built-up area. These small maps are all at the same scale, which is about 1:650 000.

Census Divisions are groupings of states and the District of Columbia that are subdivisions of the four census regions. There are nine census divisions established by the U.S. Census Bureau Puerto Rico and the Island Areas are not part of any census region or census division.

This 1:3,000,000 cartographic map product includes the federal census divisions and subdivision boundary from the most recent census year within the boundaries of Alberta. The official boundaries are updated every 5 years with the census and should be considered the most recent official boundaries. The current boundaries are from the 2021 Census of population. This information is adapted from Statistics Canada, Boundary files in their respective years. This does not constitute an endorsement by Statistics Canada of this product. This map sheet is provided in Adobe .pdf format.

Here is a selection of map services from Statistics Canada displaying socio-economic variables as thematic maps, viewed by census division. This selection covers the following themes: families and households, housing, education, language, income, immigration, aboriginal people, age and transport. Census division (CD) is the general term for provincially legislated areas (such as county, municipalité régionale de comté and regional district) or their equivalents. In other provinces and the territories where laws do not provide for such areas, Statistics Canada defines equivalent areas for statistical reporting purposes in cooperation with these provinces and territories. Census divisions are intermediate geographic areas between the province/territory level and the municipality (census subdivision). NOTE: Services by theme may not all be listed in the Related Products section below as they are added individually only once available for publication.

Census REST files provide a way for users to request TIGER\Line information from Census GIS servers files through Representational State Transfer (REST)technology. Clients issue requests to the server through structured URLs. The server responds with map images, text-based geographic information, or other resources that satisfy the request. The 2016 Census Regions and Divisions REST File contains Census Regions, Census Divisions. This Rest service contains data as of January 1,2016 .

The 2022 cartographic boundary shapefiles are simplified representations of selected geographic areas from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). These boundary files are specifically designed for small-scale thematic mapping. When possible, generalization is performed with the intent to maintain the hierarchical relationships among geographies and to maintain the alignment of geographies within a file set for a given year. Geographic areas may not align with the same areas from another year. Some geographies are available as nation-based files while others are available only as state-based files. County subdivisions are the primary divisions of counties and their equivalent entities for the reporting of Census Bureau data. They include legally-recognized minor civil divisions (MCDs) and statistical census county divisions (CCDs), and unorganized territories. In MCD states where no MCD exists or no MCD is defined, the Census Bureau creates statistical unorganized territories to complete coverage. The entire area of the United States, Puerto Rico, and the Island Areas are covered by county subdivisions. The generalized boundaries of legal MCDs are based on those as of January 1, 2022, as reported through the Census Bureau's Boundary and Annexation Survey (BAS). The generalized boundaries of all CCDs, delineated in 21 states, are based on those as reported as part of the Census Bureau's Participant Statistical Areas Program (PSAP) for the 2020 Census.

A population ecumene is the area of inhabited lands or settled areas generally delimited by a minimum population density. Two population data sets from the 2016 Census of Population were used to build two specialized ecumene maps. The census division ecumene was built from dissemination area population density data and the census subdivision ecumene was built from the dissemination block population density data. For information on census divisions, census subdivisions, dissemination areas, and dissemination blocks consult the Statistics Canada’s 2016 Illustrated Glossary (see below under Data Resources). Areas included in the ecumene (for either the census division or census subdivision) are areas where the population density is greater than or equal to 0.4 persons per square kilometre or about 1 person per square mile. In some areas to capture more population within the ecumene the criteria was extended to 0.2 persons per square kilometre. The ecumene areas were generalized in certain regions either to enhance the size of some isolated ecumene areas or to remove small internal uninhabited areas within the ecumene. Either of these ecumene resources can be used as an “ecumene” map overlay to differentiate the sparsely populated areas from the ecumene in conjunction with the appropriate census geography or other small-scale and large-scale maps.

The segment of the population between 35 and 64 years of age are considered the population in the latter half of their working life. They have, for the most part, finished having children, are in the upper end of their earning potential, children are leaving the nest, mortgages are paid and assets are increasing. This map exhibits a few interesting patterns when compared with other maps in the age structure. Compared to the early working years group, the later working years segment is less concentrated in the inner parts of the city. Higher proportions are evident on the census subdivision layer in areas outside of cities reflecting past suburban migration patterns. In the north the area outside the populated places is dominated by a high proportion of people in their later working years. Note that very small populations exist in many large census divisions and subdivisions in the North.

This map symbolizes the relative population counts for the City's 12 Data Divisions, aggregating the tract-level estimates from the the Census Bureau's American Community Survey 2021 five-year samples. Please refer to the map's legend for context to the color shading -- darker hues indicate more population.If you click on each Data Division, you can view other Census demographic information about that Data Division in addition to the population count.About the Census Data:The data comes from the U.S. Census Bureau's American Community Survey's 2017-2021 five-year samples. The American Community Survey (ACS) is an ongoing survey conducted by the federal government that provides vital information annually about America and its population. Information from the survey generates data that help determine how more than $675 billion in federal and state funds are distributed each year.For more information about the Census Bureau's ACS data and process of constructing the survey, visit the ACS's About page.About the City's Data Divisions:As a planning analytic tool, an interdepartmental working group divided Rochester into 12 “data divisions.” These divisions are well-defined and static so they are positioned to be used by the City of Rochester for statistical and planning purposes. Census data is tied to these divisions and serves as the basis for analyses over time. As such, the data divisions are designed to follow census boundaries, while also recognizing natural and human-made boundaries, such as the River, rail lines, and highways. Historical neighborhood boundaries, while informative in the division process, did not drive the boundaries. Data divisions are distinct from the numerous neighborhoods in Rochester. Neighborhood boundaries, like quadrant boundaries, police precincts, and legislative districts often change, which makes statistical analysis challenging when looking at data over time. The data division boundaries, however, are intended to remain unchanged. It is hoped that over time, all City data analysts will adopt the data divisions for the purpose of measuring change over time throughout the city.
