Family planning services promote a wide range of health and socioeconomic benefits to women, men, and their families. Still, many barriers prevent women from using contraception. Despite efforts to increase awareness and improve access to these family planning services, unmet need for family planning and unwanted pregnancies remains high in many low- and middle-income countries, suggesting that other factors may be driving contraceptive use. One such factor relates to household decisionmaking about fertility. Specifically, disagreements between a husband and wife about family planning may influence decisions about contraceptive use.
