Every five years, the Census Bureau releases two data products containing the greatest level of statistical detail for specific population groups:

Browse the resources below to learn about the available tables, geographies, population groups, and comparison guidance.
*To modify a table in data.census.gov to a specific race, Hispanic origin, or tribal population, select the "Topic" tool at the top of the table. Next, select "Race and Ethnicity." From here the table can be modified by specific race, Hispanic origin, or tribal population. Once a specifc race, Hispanic origin, or tribal population is selected, close the "Topic" tool to view the modified table. Follow similar steps to modify a table by ancestry. Select the "Topic" tool and then select "Populations and People." Next, select "Ancestry" and from here a specific ancestry can be selected. Once an ancestry is selected, close the "Topic" tool to view the modified table.
*To modify the geography of a table in data.census.gov, select the "Geos" tool at the top of the table. From here the table can be modified by Region, State, County, and more. Once a geography is selected close the "Geos" tool to view the modified table.
Explore the list of available tables, population groups, geographies, and comparison guidance for the 2017-2021 ACS 5-year Selected Population Tables (SPT) and American Indian and Alaska Native Tables (AIANT). Additional details about the contents of this documentation are described below.
Browse the lists of available Data Profiles and Detailed Tables. The 2011-2015 ACS 5-year SPT and AIANT equivalent tables are also shown where possible.
Tables will be available based on the size of the group and the number of sample cases for a specific geographic area (i.e., state or town). Steps 1 and 2 below outline the criteria for publishing estimates for groups.
The race, Hispanic origin, ancestry, or tribal population group must have a population of at least 7,000 based on the 2017-2021 ACS 5-year estimates at the national-level.
The American Indian or Alaska Native group must have a population of at least 100 based on the 2017-2021 ACS 5-year estimates at the national-level.
For the table to be released for a particular population group, the desired geographic area (i.e., the state of Florida) must have at least 50 unweighted sample persons from the population group, based on 2017-2021 ACS 5-year estimates. This requirement protects individual and household responses. View the "SPT Geographies" and "AIANT Geographies" tabs in the documentation above for more details.
Definitions of American Indian and Alaska Native tribes change over time. Reference the "SPT Comparison Guide" and "AIANT Comparison Guide" tabs in the documentation above to determine whether data for these groups are comparable to statistics from previous datasets.
