Changing patterns of extramarital conceptions in the Czech Republic, 1960-93

Patterns of reproduction associated with extramarital conception are examined using data on non-marital births, marital births occurring during less than 8 months after marriage, and spontaneous and induced abortions experienced by unmarried women. Trends in the incidence and demographic outcomes of conceptions resulting from extramarital coitus are analysed by means of age-specific probabilities of becoming pregnant outside marriage; and of terminating such a pregnancy by abortion, by legitimating it through marriage before confinement, or by having a baby while remaining unmarried. Substantial increases in the proportion of extramaritally conceived pregnancies leading to non-marital births are detected for the period since the late 1980s, and ascribed mainly to rising levels of unmarried cohabitation. The demographic effects of the post-1989 transition from state to market economy are discussed.
