Block Numbering Areas
Block Numbering Areas (BNAs) served as the rural equivalent to census tracts in the 1990 Census. They are areas defined for the purpose of grouping and numbering blocks in counties where there are no census tracts. BNAs do not cross county boundaries. They are identified by census tract-type numbers ranging from 9501.00 to 9989.99. Each number is unique within a county. BNAs may be split for tabulation purposes by the boundaries of places, MCDs and CCDs.
