Tribal Block Groups Census 2000 for Wyoming

Metadata record for U.S. Census Tribal Block Groups in 2000 for the state of Wyoming. Link to 2000 Wyoming census data page in record. A tribal block group (BG) is a cluster of census blocks having the same first digit of their four-digit identifying numbers and are within a single tribal census tract. The optimum size for a tribal BG is 1,000 people; it must contain a minimum of 300 people. The difference between a tribal BG and a nontribal BG is in the hierarchical presentation of the data. A tribal BG is part of the American Indian hierarchy; that is, the tribal BG is within a tribal census tract that is within a federally recognized American Indian reservation and/or off-reservation trust land.
