POPLOC
Person number of first father (from programming)

Codes

00 = No father of this person in the household.

Description

POPLOC is a constructed variable that indicates whether the person's father lived in the same household and, if so, gives the person number of the father (PERNUM). The method by which probable child-father links are identified is described in POPRULE.

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

  • User Caution: POPLOC identifies social relationships (such as stepfather and adoptive father) as well as biological relationships. POPLOC will also identify the unmarried partner of a child's mother identified with MOMLOC

If the person identified with POPLOC has a spouse or partner identified through SPLOC, the spouse or partner will also be identified as a parent through MOMLOC (if a different-sex couple) or POPLOC2 (if a same-sex couple). POP2RULE and MOMRULE will communicate the method through which those relationships are identified.

In 2016, the family interrelationship variables for all samples were revised to increase comparability across IPUMS projects and include same-sex couples. Many researchers who are familiar with the previous version of family interrelationship variables will find it useful to read a brief overview of the key differences of the New IPUMS Family Interrelationship Variables. On this page you'll find information on how family interrelationship variables are constructed, common uses of these variables, and specific examples of how these variables can be used efficiently.

The pre-2016 version of POPLOC and other IPUMS pointer variables are available here.

Comparability

Due to variation in the information available for linking fathers and children, there are some differences across years. For example, in 1988 and before, the non-ASEC samples did not have a "child" value on RELATE. In these samples, "other relatives" who are under 22 are allowed to link to both "Other relatives" and to the "Head" or the "Spouse" as a father when the age difference is appropriate.

Comparability with IPUMS-USA

The development of new family interrelationship variables was prompted by the desire to have more comparability between different IPUMS projects and over time. The family interrelationship variables use common logic across IPUMS CPS, IHIS, and USA (modern years). Each project has different allowed links because of different level of detail in each project, but the logic of assigning parents in ambiguous situations is the same.
