Types of consanguineous mating in relation to premarital migration and its effects on inbreeding Levels [Elektronische Daten] [R. Calderon] This Study, the first of a series on consanguinity in the Archbishopric of Toledo from 1900 to 1979, analyses in detail the types of consanguineous mating in a population of considerable size, some 650,000 persons, in central spain. during the period covered, very important transformations occurred in Spanish society. The data relate to 21,464 consanguineous marriages. They were divided into two groups, according to the premarital migration of the couple. Significant differences in the frequencies of the types of consanguineous matings, and their secular evolution, are found for the two groups. The expected trend in inbreeding in the total area shows two different tendencies: constancy till the end of the 1950s, followed by a fast decline during the last two decades.
