MOMLOC
Mothers location in household

Codes

This is a 2-digit numeric variable.

Description

MOMLOC is a constructed variable that indicates whether the person's mother lived in the same household and, if so, gives the person number of the mother (see PERNUM).

MOMLOC makes it easy for researchers to link the characteristics of children and their (probable) mothers.

The method by which probable child-mother links are identified is described in MOMRULE.

User Caution: MOMLOC identifies social relationships (such as stepmother and adopted mother) as well as biological relationships.

Comparability

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

Each sample contains a corresponding variable, POPLOC, that identifies fathers.

Family interrelationship variables were not constructed in households containing 30 or more residents. In addition, pointers were not constructed for households containing individuals with the relationship "spouse of head" unless the household could be subdivided into multiple sub-households each with a person identified as a household or family head. These limitations were necessary because of the uncertainty of family interrelationships in these households. Members in affected households receive a MOMLOC code of 0.

Canada
Constructed family interrelationship variables are available only in the 1891 and 1901 census samples, because Canada did not enumerate relationship to the household head in 1852, 1871, and 1881. Future releases of NAPP will include imputed versions of these variables, similar to the IMPMOM, IMPPOP, and IMPSP in IPUMS-USA.

Mecklenburg-Schwerin
No constructed family interrelationship variables are available because the 1819 census did not collect relationship to household head.

Norway
Sample-specific rules were implemented for the Norwegian censuses to address differences in the coding of RELATE (relationship to the head of household) and other enumeration practices.

United States
For 1850-1870, relationships to the household head are imputed.  In those years, MOMLOC is based on imputed family relationships. For more information, see the IPUMS-USA user guide.
