AVAILABLE. This study is freely available to ICPSR member institutions. Also available as downloadable files. Master Area Reference Files (MARFs) link geographic areas with their respective numeric codes. This data collection comprises preliminary data collected in a dress rehearsal census in the spring of 1978 from all persons and housing units in Richmond City, Henrico County, and Chesterfield County, Virginia. The purpose of the dress rehearsal program was to use the planned final materials and procedures in locations which simulated various conditions the Bureau would face in the 1980 Census. The data file was prepared in the same format as the 1980 Census MARF and was designed primarily by programmers for developing their software for data retrieval. This release of the MARF contains geographic items from Summary Tape File 1 (STF1), as well as population counts by race and Spanish origin, the number of one-person households, the total number of housing units, and the number of occupied and owner-occupied housing units.
