[A structural and factor analysis of fertility].
"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)
[Analysis of the influence of social status on fertility of women in Bulgaria].
"The author studies the influence [of] the social status of women upon their fertility during first marriages [in Bulgaria]. The study has been made by means of the structural-factor analysis which is based on conventional one-dimensional and two-dimensional moment distributions. The degree of variations is determined by the integral coefficient of structural differences, the mean arithmetic value, the standard deviation, coefficients of asymmetry and excess. The author discusses: 1) the changes in the structure of various categories of women according to social groups, 2) the changes in the separate structures for each of the social groups of women according to the number of live-born children during the 1965-1985 period. The method of filtering variables is used to control the influence of the important demographic factor 'duration of marriage'." Data are from the censuses of 1965, 1975, and 1985.
