Description

YNGCH gives the age of the person's youngest own child living in the household with her or him. These include all children linked to the person via the constructed IPUMS pointer variables MOMLOC or POPLOC -- mother's and father's location in the household.

YNGCH is top-coded at age 50 or older.

Comparability — General

The variable is conceptually comparable across all samples, although there is variation in the specific information used to construct the underlying mother and father pointer variables.

Some samples do not provide single years of age. In those samples, ELDCH provides the mid-point of the age range. See the variable AGE.

No constructed family interrelationship variables are available for the individual-level samples that do not contain entire households of persons.

Comparability — United States [top]

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