for social services, public health, and the health services in Sweden. Among the board's responsibilities are evaluation and monitoring of abortions performed in Sweden, as well as establishing norms by issuing provisions and general advice. The board is also responsible for the collection and publishing of official national statistics on abortions. Until 1995 reports were instead published by Statistics Sweden. Statistical reports are published yearly and are based on data from all clinics and hospitals where abortions are performed. Data is collected on the age of the women, earlier pregnancies and abortions, the length of the pregnancy at the time of abortion, method of abortion, and where the abortion was performed. One of the National Health Board's main purposes with these reports is to measure changes and trends over time. The statistics on legal abortions stretches back to 1955 and, starting from 1975, data on frequencies for different age groups are available. From 1985 the women's home municipality was also recorded. Trends The number of induced abortions performed in Sweden rose markedly on a yearly basis from the early 1960s, but soon leveled off following the liberalization of the abortion law in 1975. It is not possible to tell whether the increase in the statistics after the Abortion Act of 1974 reflects actual circumstances, or just bias resulting from an increased will to report abortions after legalization. Since 1975, the total yearly number of cases has averaged between 30,000 and 38,000 abortions. The number of abortions by age group were as follows: those performed on teenagers in 1975 were 30 in every 1,000, while those performed on women aged 20 to 24 years old was 27 in every 1,000. However, since 1977, the opposite has held true, with fewer abortions being performed on teenagers than women aged 20 to 24. The number of abortions among teenagers was around 11 per 1,000 women in 2018, a halving since 2009. Most abortions in Sweden are performed on women aged 25–29 years old, followed in order by the age groups 20–24 years old, 30–34 years old, 35–39 years old, 15–19 years old (teenage abortions), and 40–44 years old. Before the age of thirty most women have not established a family life and abortion is more common amongst this age group, with multiple sex partners in the younger age groups parenthood is less desired and abortion more likely.
