The American Housing Survey metropolitan survey datasets include a variable, ZONE, indicating a sub-metropolitan geographic area. These files are maps showing the location of these zones in each metropolitan area. Note that for many metropolitan areas there are two sets of maps: one based on 1980 metropolitan area geography, and used for surveys before 1995, and another using updated metropolitan area geography and used for surveys in 1995 and later.
