A retrospective investigation was undertaken of all the births and abortions during the period 1974-1986 in the County of Funen. The material comprised 66,020 births, 23,179 induced abortions, 9,270 spontaneous abortions and 1,344 ectopic pregnancies. The distributions of the various types of pregnancy were assessed for the entire period and correlated with the age of the women. Comparison of the circumstances in 1974 and 1986 revealed significant changes (p less than 0.05) for pregnant women greater than or equal to 35 years with the following values: the number of births increased 20%, the number of spontaneous abortions increased 56%, the number of ectopic pregnancies increased 240% and the number of induced abortions fell 31%. These numerical values are probably representative for all Denmark.
