Description

MOMLKREA reports the method by which mother-child links were made or rejected, as determined by the creators of the 1910 samples that were developed prior to the existence of the IPUMS (these include the national 0.4% 1910 sample and the 1910 Black oversample). These samples have since been integrated into the IPUMS as part of the "1910 1.4% sample with oversamples." The cases containing MOMNKREA are identified in the SAMP1910 variable, where they have values of 5 or 6.

"Simple links" were those made following the rules listed in MOMNO. "Simple rejects" were made in all one-person households, and in cases where the only female in the household was the head's wife and no one in the household was listed as the son, daughter, or child of the head. "Probability" and "hand" links or rejects were made according to a more complicated system, based upon the weighting factors listed in MOMLNKWT.

Codes

This variable is not available for any of the currently selected samples.

Comparability

This variable is only available for the 1910 1.4% sample with oversamples. MOMRULE reports the rationale for mother-child links made for MOMLOC, an IPUMS constructed variable available for all years.
