Generalizations about differences in marital survival rates among religiously homogamous and interreligious marriages are limited by sampling and other methodological considerations. Data collected by the Division of Vital Statistics of the Iowa State Department of Health provided an opportunity for undertaking more precise tests of differences in marital survival rates among religiously homogamous and interreligious marriages. In Iowa since 1953 the religious affiliations of brides and bridegrooms have been listed on marriage records, and the affiliations of husbands and wives have been listed on divorce records. These data were used to define various types of religiously homogamous and interreligious marriages and divorces which occurred in Iowa from 1953 through 1959.
A method was developed to estimate the survival rates for various types of marriages for each of the years from 1953 through 1959. The seven yearly estimates were used in a regression equation for predicting survival rates among the various religious types for the eighth year. The survival rates for the eighth year were used to test a series of hypotheses for differences in survival rates among religiously homogamous and interreligious marriages. Ages of the brides and occupations of the husbands were used separately and jointly as control variables in the analyses.
