Every year, at least 1 million Tanzanian women and girls are faced with unwanted or unplanned pregnancies. Of those, 39% end in abortions. This indicates that in order to address the high rate of unsafe abortions in Tanzania, it is crucial to understand the factors and resulting human rights violations that lead to unwanted and unplanned pregnancies. This factsheet discusses some of these factors including the limited access to contraceptive information and services in Tanzania and highlights the disproportionate effect this has on vulnerable groups such as women living in rural areas and those with limited economic means. It also discusses lack of access to reproductive health information and services for adolescents and victims of sexual violence.
