[Changing trends in illegitimate live births in the Czech Republic]

The authors analyze changes in the rate of illegitimate births in the Czech Republic. They find that "the slowly but fluently increasing percentage of illegitimate live births...is accompanied by a faster decline of infant mortality of these children compared to legitimate ones and by the same decline of the percentage of births having a low natality weight in both groups.... The differences of the percentage of illegitimate children born to mothers of various age groups were almost constant in the years 1974-1988, i.e. the number of illegitimate children delivered by mothers of different age, had grown approximately equally."
