A Tribal Census Tract is a small, relatively permanent statistical subdivision of a federally recognized American Indian reservation and/or off-reservation trust land, delineated by American Indian tribal participants or the Census Bureau for the purpose of presenting data. Designed to be relatively homogeneous units with respect to population characteristics, economic status, and living conditions, tribal census tracts average about 2,500 people.  A tribal census tract must consist of territory located on a reservation/trust land. The boundaries of tribal census tracts may cross state and/or county lines, and normally follow visible features, but may follow governmental unit boundaries and other nonvisible features in some instances.   For the 2010 Census, the tribal census tracts were defined independently of the standard county-based census tracts and have numbers that are six characters long leading with a “T” alphabetic character followed by five numeric codes having an implied decimal between the fourth and fifth character; for example, T01000, which translates as tribal census tract 10.A Tribal Block Group (BG) is a subdivision of a tribal census tract. A tribal block group is the smallest geographic unit for which the Census Bureau tabulates sample data. Tribal BGs are delineated by American Indian tribal participants or the Census Bureau, and average about 1,000 people.   For the 2010 Census, tribal block groups were delineated independently of the county-based block groups and use a letter ranging from A through K (except “I”, which could be confused with a number “1”) to identify and code the tribal block group. This was done to better identify and differentiate tribal block groups from county-based block groups. Data currency: January 1st, 2014Visibility: Data is visible at a Counties level scale (~1:1,200,000) and larger.Other Federal User Community federally focused content that may interest you Department of Commerce                               Census Bureau Open Data: USDOC                                          Open Data: Census Bureau
