title: [A structural and factor analysis of fertility].
abstract: "The article examines the influence of the age at the time of the study on the fertility of women aged between 15 and 49 in their first marriage.   The analysis is based on the variation between conditional one-dimensional distributions.... On the basis of data from the censuses in Bulgaria of...1965, 1975 and 1985, the author specifies some tendencies in the change of the fertility level, as well as the nature of the relation between the age at the moment of study and fertility.  The article also makes an attempt to study the relation between the duration of the marriage and the fertility of women aged between 15 and 49 [who are] in their first marriage." (SUMMARY IN ENG)
