Summary File 2 will be available for up to 331 population groups and each of the 50 states, the District of Columbia and Puerto Rico. The information will be available for a variety of geographic areas, down to the census tract level.

The U.S. Census Bureau today released new, detailed demographic information from the 2010 Census for up to 331 different race and ethnic groups down to the census tract level for Oklahoma and Oregon.

These Summary File 2 tables add a new layer of detail to the population and housing topics released last year from the 2010 Census. Information, such as age, relationship and homeownership, previously available only for an area's entire population is now available for specific race and ethnic groups in that community.

Each Summary File 2 table is presented for up to 331 population groups. These include iteration groups for the total population, race alone groups, race alone or in combination groups, multiple-race combinations, American Indian and Alaska Native tribal groupings, detailed Asian groups, detailed Native Hawaiian and Other Pacific Islander groups, detailed Hispanic groups, and race/Hispanic groups.

Geographies Available

The statistics are available for a variety of geographic areas: counties, county subdivisions, places, census tracts, ZIP Code tabulation areas, congressional districts for the 111th Congress, American Indian and Alaska Native areas within the states released, tribal subdivisions, metropolitan areas and Hawaiian home lands.

To preserve confidentiality, only geographic entities with a population of at least 100 for the specified group are available in the summary file.

Accessing the Information

The Summary File 2 tables can be found on the Census Bureau's American FactFinder website at <http://factfinder2.census.gov> by using the "Population Groups" filter to select the specific race or ethnic groups of interest. While a variety of tables will be available, a good place to start is the Profile of General Population and Housing Characteristics, which shows a summary of characteristics for one geographic area at a time.

A summary file version of the information is also available for users who want to download the set of detailed tables for all of the geographies within a state and run their own analysis and rankings. The summary file contains two parts: a file with the geographic headers (in fixed-length ASCII format) and a file with the statistical information (in comma-separated ASCII format). The summary file is available for download at <http://www2.census.gov/census_2010/05-Summary_File_2/>.

For local context, contact your state data center: <http://www.census.gov/sdc/network.html>.

Editor's note: Summary File 2 will be publicly available via FTP at 12:01 a.m. EST, Thursday, Jan. 26 and in American FactFinder by 10 a.m. EST Thursday, Jan. 26.

The U.S. Census Bureau today released a 2010 Census brief, The American Indian and Alaska Native Population: 2010, that shows almost half (44 percent) of this population, or 2.3 million people, reported being American Indian and Alaska Native in combination with one or more other races. This multiracial group grew by 39 percent from 2000 to 2010.

Overall, 5.2 million people, or 1.7 percent of all people in the United States, identified as American Indian and Alaska Native, either alone or in combination with one or more races. This population grew by 27 percent from 2000 to 2010. Those who reported being American Indian and Alaska Native alone totaled 2.9 million, an increase of 18 percent from 2000 to 2010. The multiple race American Indian and Alaska Native population, as well as both the alone and alone-or-in-combination populations, all grew at a faster rate than the total U.S. population, which increased by 9.7 percent from 2000 to 2010.

More Than Three-Fourths Live Outside Tribal Areas

A majority of the American Indian and Alaska Native alone-or-in-combination population (78 percent) lived outside of American Indian and Alaska Native areas. At the same time, most counties with relatively higher proportions of American Indians and Alaska Natives tended to be in close proximity to reservations, trust lands or Oklahoma tribal statistical areas. This was especially evident in counties throughout the West and in Oklahoma.

Majority Live in 10 States

The 10 states with the largest American Indian and Alaska Native alone-or-in-combination population in 2010 were California, Oklahoma, Arizona, Texas, New York, New Mexico, Washington, North Carolina, Florida and Michigan. Among these states, Texas, North Carolina and Florida experienced substantial rates of growth in this population at 46 percent, 40 percent and 38 percent, respectively. The American Indian and Alaska Native alone population experienced growth of at least 20 percent in Texas, North Carolina, Florida and New York.

The multiple-race American Indian and Alaska Native population increased by more than 50 percent in 18 states. North Carolina, Delaware and South Dakota experienced the most rapid growth in this population at more than 70 percent. In all but three states, the multiple-race proportion of the American Indian and Alaska Native alone-or-in-combination population increased from 2000 to 2010.

Tribal Groupings

The largest number of people who identified with an American Indian tribal grouping, either alone or in combination, identified as Cherokee (819,000). The Navajo tribal grouping had the largest number of individuals who identified with one tribal grouping and no other race (287,000).

Among the largest American Indian tribal groupings, Blackfeet had the highest proportion who reported more than one tribal grouping or race. Seventy-four percent of Blackfeet individuals reported an additional race and/or tribal grouping.

     The largest Alaska Native tribal grouping, either alone or in combination, was Yup'ik (34,000), followed by Inupiat (33,000). Yup'ik also had the greatest number of people who identified with one tribal grouping and no other race (29,000).

Among all Alaska Native tribal groupings, Tlingit-Haida had the highest proportion who reported more than one tribal grouping or race. Forty-two percent of Tlingit-Haida individuals reported an additional race and/or tribal grouping.

Race Definitions

People who reported only one race on their 2010 Census questionnaire are referred to as the race “alone” population. For example, respondents who marked only the “American Indian or Alaska Native” category would be included in the American Indian and Alaska Native alone population. This population can be viewed as the minimum number of people reporting American Indian and Alaska Native.

     Individuals who chose more than one of the six race category options on the 2010 Census form are referred to as the race "in combination" population, or as the group who reported more than one race. One way to define the American Indian and Alaska Native population is to combine those respondents who reported American Indian and Alaska Native alone with those who reported American Indian and Alaska Native in combination with one or more other races. Another way to think of the American Indian and Alaska Native alone-or-in-combination population is the total number of people who reported American Indian or Alaska Native, whether or not they reported any other races.
