From my reading of the IMPUS site, it seems that none of the samples based on census manuscripts have address information. Is that correct? Can you recommend another source that where I could download census microdata with address information? (Actually, for my purposes, a tract indicator would be sufficient.) I’m particularly interested in census years 1920 and before (I know there is aggregate tract-level information for some cities before 1930, but I am interested in Los Angeles, where tract data only begin in 1930).
