SAS Transport Files, v1 (1990)

Downloads:

The entire 1990 STF3A database has been grouped by state according to the state postal codes and subdivided by the following geographic summary levels: state and county (slvl=040 and slvl=050), county subdivision/mcd (slvl=060), tracts (slvl=140), blockgroup (slvl=150), places (slvl= 155), and others (all other slvls). The other summary level includes groups such as Indian reservations, tribal districts, congressional districts, etc. The tabulation geographies, the split-blockgroups (slvl=090), split-tracts (slvl=080) and split-places (slvl=070), have been extracted into individual files by state. A detailed description of the variables have been compiled in the file 3xptvar.lst.
