Census of Population and Housing, 1980 [United States]: Master Area Reference File (MARF) 2

MARF is the 1980 Census counterpart of the Master Enumeration District List (MEDList) prepared for the 1970 census. It links state or state equivalent, county or county equivalent, minor civil division (MCD)/census county division (CCD), and place names with their respective geographic codes. It is also an abbreviated summary file containing selected population and housing unit counts. MARF 2 has the same geographic coverage as the first MARF and includes the following additional information: FIPS place codes, latitude and longitude coordinates for geographic areas down to the BG/ED level, land area in square miles for geographic areas down to the level of places or minor civil divisions (for 11 selected states) with a population of 2,500 or more, total population and housing count estimates based on sample returns, and per capital income for all geographic areas included in the file. There are 51 files, one for each state and the District of Columbia.
