Comparability

For 1940 and 1950, persons sampled as individuals from within group quarters are coded N/A; in other years, such persons would receive the code 1 if they were the first person sampled from within group quarters. In other respects, this variable is comparable across years. Surnames are reported in the alphabetic variable NAMELAST for the 1850-1900 and 1920-1930 U.S. Censuses and for the 1910-1920 Puerto Rican Censuses.
