Description

NCHILD counts the number of the person's own children (of any age or marital status) residing with the respondent. These include all children linked to the person via MOMLOC/MOMRULE or POPLOC/POPRULE. This variable includes step-children and adopted children, along with the biological children. Persons with no children present are coded "0".  NCHILD is top-coded at 9.

Comparability

This variable is comparable for all countries, but see the discussion on Family Interrelationships for discussion of these NAPP constructed variables.

Canada
No constructed family interrelationship variables are available for 1852, 1871, and 1881 Canadian censuses, and Canada did not enumerate relationship to household head in these years. However, information about family interrelationship can be deduced from RELATE in 1891 and 1901 censuses.

Mecklenburg-Schwerin
No constructed family interrelationship variables are available for the Mecklenburg-Schwerin census of 1819, which contains no information on relationship to household head.

United States
The comparability of this variable is affected by the information available on family relationships. NCHILD is based on the information contained in RELATE (Relationship to household head), MOMLOC, and POPLOC, for all years except 1850-1870. In these years, relationships to the household head are imputed and FAMSIZE is based on imputed family relationships. For more information, see the IPUMS-USA user guide.
