CensusCD 1980 in 2000 Boundaries makes it easy to select specific geographic areas of interest to customize your project. All of the data is given in 2000 geographic boundaries as if the 2000 boundaries had existed when the 1980 census was taken. Our program allows you to select geographies across state lines, so for example if you need information on tracts for one county in Maine and three in California and another two in New York, you can have data for all of the tracts in all 6 of these counties all in one report. More importantly the program will automatically break down one or more larger areas into component units. For instance getting New York, Ohio and Pennsylvania reported by tract, place, or county is a snap. Compare this to data vendors who only provide raw data and want to sell you only one state or county at a time. CensusCD 1980 in 2000 Boundaries has data at 12 levels of geography:

Nation (1)
State (51)
County (3,141)
Tracts (65,232)
Block Groups (208,790)
Places (25,150)
MCD/CCD (35,164)
Congressional districts (436)
Zip (ZCTA) (32,232)
MSA/CMSA (280)
CMSA/PMSA (76)
American-Indian Reservations (651)

In 1980 the country was not fully tracted, in fact only about 80% of the population (and 50% of the land) was within these tracted areas. Block Groups accounted for even less of the areas.
