In earlier years, only total record count was reported. However, in the "Weighted and Unweighted Counts" table, the total records are equal to "Total Persons" + "Total Units" (Households) + "Total Family Records in Households" + "Total Family Records in Group Quarters". ---------------------------------------------------------------------- http://www.bls.census.gov/cps/bsrcacc.htm says: 1. For the years 1967 through 1995, multiply the standard errors by 0.96. 2. For the years 1956 through 1966, multiply the standard errors by 1.17. 3. For years prior to 1956, multiply the standard errors by 1.44. 1973 CPS -- administrative record exact match file codebook, part1 -- code counts and item definitions. interagency_data_linkages.pdf The cpsjan78.pdf has a user note: "Users of the Non-March CPS supplements are cautioned that variables for individual records which are not in the universe may contain meaningless alphanumeric codes. When analyzing variables which (1) do not apply to the total universe and (2) do not have a specific not-in-universe code, a test should be made for the universe criteria to eliminate these meaningless codes.
