     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 the final set of states: Alabama, Arizona, Delaware, Kansas and Pennsylvania. Additionally, the Census Bureau released a national file containing information for the U.S., regions, metropolitan statistical areas and other geographic areas that may cross state boundaries.

     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.

     The following national-level highlights on median age provide an example of the characteristics available for up to 331 detailed race and Hispanic origin groups.

Detailed Hispanic or Latino Origin Groups

• Among detailed Hispanic groups nationwide, Mexican was the youngest with a median age of 25.5, while Cuban was the oldest with a median age of 40.1.

American Indian and Alaska Native Tribal Groupings

• Among detailed American Indian and Alaska Native Tribal groupings, the Pima tribal grouping alone or in any combination was the youngest with a median age of 23.2, while the Delaware tribal grouping alone was the oldest with a median age of 40.9.

Detailed Asian Groups

• Among detailed Asian groups, the Hmong alone or in any combination population was the youngest Asian group with a median age of 20.5. Meanwhile, Okinawan alone was the oldest with a median age of 55.4.

Detailed Native Hawaiian and Other Pacific Islander Groups

• Among detailed Native Hawaiian and Other Pacific Islander groups, Marshallese alone was the youngest with a median age of 20.3. Meanwhile, Tokelauan alone was the oldest with a median age of 41.4.

Multiple Race Population

• Among population groups that reported two or three races, the white-black-Asian population and the white-black-Native Hawaiian and Other Pacific Islander population tied as the youngest groups with a median age of 11.3.
• Meanwhile, the white-American Indian and Alaska Native population was the oldest group, with a median age of 31.4.

     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, such as 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 and micropolitan statistical 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.

     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/>.
