Archive of Census Related Products
(ACRP): 1990 Standard Extract Files
The
1990 Standard Extract Files portion of the Archive of Census
Related Products (ACRP) contains population and housing data
derived from the U.S. Census Bureau's 1990 STF3A database.
The population data includes age distribution, education levels,
ethnicity, income distribution, labor force status and family
structure, while the housing data embodies size and state
of the housing unit, value of the unit, water, sewage, heating,
and monthly owner costs. The data are available by county,
county subdivisions, place within-county, tract, block numbering
area (bna), and blockgroup. Each file contains a unique POLygon
IDentification (POLID) field which matches a similar field
in the corresponding TIGER-based boundary file. Tract and
blockgroup files are grouped by MSA (Metropolitan Statistical
Area) and CMSA (Consolidated Metropolitan Statistical Area).
This portion of the ACRP is produced by the Columbia University
Center for International Earth Science Information Network
(CIESIN).
