Comparability

From 1850 to 1930 and in the ACS, all parent-child relationships can theoretically be identified, but for censuses from 1940 onward parent-child relationships cannot be identified for persons in group quarters. Group quarters individuals in the period since 1940 are coded 99 (N/A) in YNGCH, even though on rare occasions parents in group quarters may actually have resided with their children.

The comparability of this variable is affected by the information available on family relationships, including MOMLOC,MOMLOC2, POPLOC, and POPLOC2. MOMLOC2 and POPLOC2 are available only in 1970 and later. In 2017, the family interrelationship variables for samples from 1970 to present were revised to increase comparability across IPUMS projects and include same-sex couples. Samples prior to 1970 continue to use the original version of family interrelationship variables. Users will find it useful to read a brief overview of the key differences of the New IPUMS Family Interrelationship Variables.

YNGCH is based on the information contained in RELATE (Relationship to household head), MOMLOC, and POPLOC, for all years except 1850-1870. In these years, it is constructed from IMPREL (Imputed relationship). See MOMRULE, POPRULE and "Family Interrelationships" for a discussion of variations across years in these variables.
