In England and Wales, about 30% of all pregnancies are unintended, and around 20% of all pregnancies end in abortion. In the US, which has one of the highest rates of unintended pregnancy in the developed world, about half of all pregnancies are unintended. Of these, approximately 40% end in abortion. Between 2008 and 2014, the abortion rate declined from 19.4 to 14.6 in 1000 women aged 15-44 years, with the US Centers for Disease Control and Prevention reporting its lowest number of abortions in 2014. Although the overall abortion rate in the US has declined, this is not seen across all population groups, with higher rates of unintended pregnancy and abortion in disadvantaged groups. This disparity suggests that there is limited access to contraception for some women and adolescents, and points to the importance of addressing birth control with all patients at risk of unintended pregnancy.
Availability of contraceptives differs between regions, and local guidelines should always be consulted.
