*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.

Summary File Data
Tables Available
Browse the lists of available tables. A Census 2000 Summary File 4 (SF4) and American Indian Alaska Native Summary File (AIANSF) Equivalent Table is also shown where possible.
Population Groups and Geographies Available
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.
Step 1-Population Groups Available
Access the code lists below to determine if tables are available for your population group.
For Selected Population Tables:
The race, Hispanic origin, ancestry, or tribal population group must have a population of at least 7,000 at the national-level.
- For race, Hispanic origin, and tribal groups, this is based on 2010 Census counts.
- For ancestry groups, this is based on 2006-2010 ACS 5-year estimates.
- There are 392 population groups included in the 2006-2010 ACS 5-year Selected Population Tables.
For American Indian and Alaska Native Tables:
The American Indian or Alaska Native group must have a population of at least 100 at the national-level.
- This is based upon 2010 Census counts for specific American Indian tribes and Alaska Native villages.
- There are 950 population groups included in the 2006-2010 ACS 5-year AIAN Tables.
Step 2-Geographies Available
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 2006-2010 ACS 5-year estimates. This requirement protects individual and household responses.
