资源简介：
This is a point coverage of the 1990 Census of Population and
Housing for the conterminous United States. (Alaska and Hawaii are
available separately). The coverage contains the location of
population points retrieved at the block group summary level and
shows the total number of persons and housing units enumerated in
the "100 percent processing" component of the decennial census.
The data was extracted from CD-ROMs containing Public Law 94-171
counts. These are counts that States use in redistricting.
