Master Area Reference Files (MARFs) link geographic areas with their respective numeric codes. This data collection is a five-digit ZIP-code equivalency file created for the 1980 Census of Population and Housing. The data contain geographic items from Summary Tape Files 1A and 3A, as well as total population and housing unit counts. This equivalency file was created to allow users to prepare additional data summaries relevant to ZIP-code areas. The file enables users to equate detailed record files having ZIP codes with census geographic units. This national file is hierarchically sequenced by geographic area.
