From 2015-2017, approximately 73.3 million abortions occurred worldwide each year. Furthermore, data from 2010-2014 showed that around 45% of these abortions were unsafe abortions, where most of these unsafe abortions occurred in developing countries. In particular, it was estimated that over 50% of the unsafe abortions occurred in Asia, with most in south and central Asia, and Africa. Global data from a 2008 systematic analysis also estimated that complications from unsafe abortions accounted for 13% of all maternal deaths. Furthermore, in a retrospective case study, it was found that maternal mortality associated with<unk>  was approximately 19%; however a systematic review of global data is still needed.<unk>  is of highest prevalence in vulnerable populations living in resource-poor environments, with prevalence reaching as high as 86% in these populations. Within such environments, the incidence of<unk>  is highest among teenagers, and in areas with restrictive abortion laws due to a higher utilization of illicit abortion procedures carried out by non-doctors due to the inherent barriers in obtaining abortion. Therefore, "societies with high fertility rate, low contraceptive usage, and legal obstacles to safe termination of pregnancy" predisposes the society to a higher prevalence of<unk> . Nevertheless, although the incidence of<unk>  is highest among teenagers between the ages of 16 and 24 years, which constitutes two-thirds of the population affected by<unk> ,<unk>  complications are still common in older married people who are assigned female at birth. The epidemiology of<unk>  is therefore dictated by risk factors and barriers to safe abortion.
