The reasons for the increasing number of abortions are complex and multifaceted, and cannot be attributed solely to a woman's relationship with a man.  Factors such as lack of access to contraception, social and economic pressures, inadequate sex education, and personal health problems also lead to the decision to have an abortion.  The social impact of abortion in many countries is complex.  In many societies, abortion is still highly stigmatized, and women who seek abortion face social exclusion and discrimination.  In some Asian countries, particularly China and India, the practice of sex-selective abortion has resulted in an imbalanced sex ratio and gender distribution, with a disproportionate number of male births.  In some countries, government policies and programs have used abortion as a means of population control and family planning.  This can have long-term social and economic impacts, including affecting population size and composition.
