I was interested in obtaining a Geographic Correspondence file, particularly Block Group to Block, for every state, containing allocation factors for Population, Land Area & Housing Units. Is it possible to obtain these .csv files directly from you?

Allocation factors from blockgroup to block aren’t part of our archive, but population and housing data extracted from the 1990 STF1B database can be accessed from  The population items include total population, age, race, and hispanic origin. The housing items include number of housing units, tenure, room density, mean contract rent, mean value, and mean number of rooms.
