Age is reported for five-year age groups. This data is Esri's current year projections.
Age Dependency Index
The ratio of the young population (<15 years) and the older population (65+ years) to the working age population (15–64 years).
Average Household Size
The average size is calculated by dividing the number of persons in households by the number of households.
A census block is a component of a block group, identified by a four-digit code. Blocks are small in area, in general, especially in cities. However, blocks in rural or remote areas may cover hundreds of square miles. A block code that starts with a zero indicates a water-only block. There are 6,237,933 census blocks.
The Core Based Statistical Area FIPS code and name. The total number of CBSA Codes in this release is 917.
Census Block Group
A block group is a collection of one or more blocks and a statistical division of a census tract, identified by a one-digit code. Block groups do not cross census tract, county, or state boundaries. In general, a block group is comprised of 600 to 3,000 residents. A zero block group code indicates a water-only BG. Boundary changes and code restructuring are reflected in the Census 2010 release. There are 239,203 block groups.
Census Latitude/Census Longitude
The centroid indicating the position of the block group or tract in which the address record is found. The GEOLEVEL field indicates whether the values represent a block group or tract.
Census tracts are small statistical subdivisions of a county, with 1,200 to 8,000 residents typically. The boundaries are usually delineated by local committees, and do not cross county or state lines. Tracts are identified by a six-digit code, with an implied decimal between the fourth and fifth digit. Boundary changes and code restructuring are reflected in the Census 2010 release. There are 84,112 census tracts.
County FIPS Code
Counties are the primary legal divisions of a state, identified by a two-digit state FIPS code and a three-digit county FIPS code. Boundary changes, as well as code and name changes, occurred in Alaska. Specifically, three codes were dropped and five new codes and names were added. There was also a slight change to a county name in Illinois and New Mexico. There are 3,143 counties in Census 2010 geography.
County subdivisions are the primary divisions of counties and include census county divisions (CCDs), minor civil divisions (MCDs), census subareas, and unorganized territories. CSDs can be uniquely identified using a two-digit state FIPS code, three-digit county FIPS code, and five-digit CSD FIPS code. There are 35,545 county subdivisions.
Summarizes racial and ethnic diversity and shows the likelihood that two persons, chosen at random from the same area, belong to different race or ethnic groups.
Households in which one or more persons in the household are related to the householder (formerly, the head of the household) by birth, marriage, or adoption. The Census tabulates only one family per household. This data is Census 2010.
Federal Information Processing Standards for numeric codes used to identify states and counties.
The geocode is a 12-digit block group code, or 11-digit tract code representing the location of the geocoded address.
The geocode level is a single character describing the geographic level of the geocode:
Defined by self-identification, Hispanic origin refers to ethnicity, not race. Persons of Hispanic origin may be of any race.
A household is an occupied housing unit. Household type is identified by the presence of relatives and the number of persons living in the household. Family households, with or without children, include married couples and other families—a male or female householder with no spouse present. Non-family households may be a group of unrelated persons or a single person living alone.
Household Income Base
The sum of the household income distribution.
Current year Income is a forecast of income for the calendar year 2010. Income amounts are expressed in current dollars, including an adjustment for inflation or cost-of-living increases. This data is Esri data.
The centroid indicating the position of the geocoded address record.
The name of the locator used to obtain the latitude, longitude, and geocode of the geocoded address.
Indicates the accuracy of the latitude and longitude that have been assigned to each address record. The Match Code is made up of five characters: the first indicates whether any match could be made (M = match and U = unmatched); the second indicates which of the locator files the address record was matched to; the last three numerical digits represent a score (100 being perfect).
Median is a value that divides a distribution into two equal parts. A median is a positional measure that is unaffected by extremely high or low values in a distribution that can affect an average.
Median age is calculated from the distribution of age by five-year groups. The data is Esri's current year projections. See Median.
Median Household Income
This is the value that divides the distribution of household income into two equal parts. Pareto interpolation is used if the median falls in an income interval other than the first or last. For the lowest interval, <$15,000, linear interpolation is used. If the median falls in the upper income interval of $200,000+, it is represented by the value of $200,001.
Per Capita Income
This is the average income for all persons calculated from the aggregate income of persons 15 years and older.
Places include incorporated places (usually cities, towns, villages, or boroughs), census designated places, and balance portions of consolidated cities. Places are uniquely identified using a two-digit state FIPS code and a five-digit place FIPS code. There are 31,615 places.
This is the total number of residents in an area. Residence refers to the "usual place" where a person lives, not necessarily the legal residence. For example, college students are counted where they attend school.
Defined by self-identification, race detail from Census 2010 contains the six basic race categories: White, Black or African American, American Indian or Alaskan Native, Asian, Native Hawaiian or Other Pacific Islander, and "some other" race for persons who do not identify with one of the specified groups. Esri forecasts race for all single and multiracial populations that are consistent with 2010 Census tabulations.
Rate, Annual Percent
Calculated as an annual compound rate of change from 2010 to the current year and future year for population, households, families and income.
States are identified by a two-digit FIPS code. The District of Columbia is included as a state-equivalent area in the Esri database. See FIPs Code.
Tapestry is Esri's market segmentation system. There are 68 types; 67 distinct residential Tapestry segments and one unclassified segment.
Tapestry Match Level
Indicates the geography level that Tapestry has been appended to each record.
Tapestry LifeMode Code
Tapestry's 68 segments are organized into 14 LifeMode groups based on lifestyle and life stage composition. For instance, Group L1, Affluent Estates, consists of the five most affluent segments, whereas Group L9, Senior Styles, includes the six segments with a high presence of seniors.
Tapestry Urbanization Code
Tapestry's 68 segments are also organized into six Urbanization groups to highlight another dimension of these markets. These six groups are based on geographic and physical features, such as population density, size of city, location in or out of a metropolitan area, and whether or not a group is part of the economic and social center of a metropolitan area. For example, U1, Principal Urban Centers, includes eight segments that are mainly in densely settled cities within a major metropolitan area.
Created by the U.S. Postal Service to deliver the mail, ZIP Codes do not represent standard census geographic areas for data reporting. Because ZIP Code boundaries are not contiguous with census geographic areas or stable over time, data estimated for ZIP Codes are also subject to change. Residential ZIP Code data are estimated from block group data, using a correspondence file created by assigning Census 2010 block points to ZIP Code boundaries from HERE. The vintage of the ZIP Code boundaries varies by year, see Tapestry Segmentationfor more information.
