Description

Definition

This variable indicates the reason why the IPUMS variable MOMLOC (mother's location in household) linked the person to a probable mother. The IPUMS establishes mother-child links according to seven basic rules, and this variable reports the number of the rule for the link in question. If a link could be made according to more than one rule, the lowest-numbered rule was applied.
