Ending Child Marriage Is a Health, Rights and Economic Imperative
The United Nations General Assembly has designated November 27 as the International Day for the Elimination of Child, Early and Forced Marriage, following a resolution led by Sierra Leone and unanimously adopted on September 4. The establishment of 27 November as the new International Day for the Elimination of Child, Early and Forced Marriage gives the world another opportunity to confront one of the most persistent violations of the rights of girls.
Child marriage remains deeply embedded in the social and economic realities of many African communities. UNICEF estimated in 2022 that Africa was home to approximately 130 million girls and women who had been married before the age of 18. The burden is particularly acute in parts of West and Central Africa, while Eastern and Southern Africa also continue to record high levels of child marriage.
A girl who marries at 14, 15 or 16 has her entire life trajectory reshaped by social norms and gendered expectations that position girls primarily in relation to marriage, motherhood and unpaid care. These norms interrupt education, narrow economic opportunities, constrain bodily autonomy and reproduce unequal power relations in which girls have far less control over decisions about sex, contraception, pregnancy, household resources and the direction of their own lives. he consequences follow girls into adulthood and, often, into the next generation. The consequences follow girls into adulthood and, often, into the next generation.
Early marriage sets in motion a cycle of early and repeated pregnancy, particularly where girls have limited power to negotiate sex, contraception, birth spacing or whether to continue a pregnancy. These pregnancies are not experienced equally: age, poverty, nutritional status, access to antenatal care, exposure to violence and the quality of the health system all shape the level of risk a girl faces. For some, pregnancy may mean interrupted schooling and increasing economic dependence; for others, it may bring serious maternal health complications, mental distress, obstetric injury or the loss of a pregnancy or newborn. Closely spaced and repeated pregnancies can deepen these vulnerabilities, while care responsibilities further restrict girls’ opportunities to return to education, enter paid work or exercise autonomy over their futures. The effects can then extend to their children through poorer health, reduced household resources and constrained educational opportunities, reproducing gendered disadvantage across generations.
Child marriage is also a health crisis
Marriage is frequently followed by pregnancy. Yet the body of a young adolescent may not be physically ready for pregnancy and childbirth. Adolescent mothers face higher risks of complications including eclampsia, infections and other adverse maternal outcomes. Their babies also face greater risks of prematurity, low birth weight and severe neonatal complications. There are equally important sexual and reproductive health consequences. A married adolescent may have little power to negotiate contraception, condom use, when to have sex, whether to become pregnant or how many children to have. Child marriage is associated with greater exposure to intimate partner violence and sexually transmitted infections, including HIV.
The mental health consequences deserve far greater attention than they currently receive. A child may suddenly be removed from school, separated from friends, expected to manage a household, become sexually active and begin childbearing while still navigating adolescence herself. Depression, anxiety, trauma and social isolation become a norm in these circumstances.
Economic Consequences
There is also an economic consequence that African governments cannot afford to ignore. When girls leave school early, they lose access not only to formal education but also to the skills, networks and qualifications that shape later participation in the labour market. Their opportunities for decent work, entrepreneurship and economic independence narrow considerably, while dependence on spouses or extended family often increases.
Early marriage can therefore lock girls into a cycle of unpaid care, low-paid work and limited asset ownership. Once pregnancy and childcare responsibilities begin, the possibility of returning to school or entering formal employment becomes even more difficult. This has consequences for lifetime earnings, savings, access to credit and the ability to build economic resilience.
The effect is not confined to individual households. At scale, child marriage reduces women’s labour-force participation, weakens productivity and limits the pool of skilled workers available to national economies. Higher fertility associated with early marriage can also increase pressure on household incomes and public services, including health, education and social protection.
For governments already managing constrained fiscal space, the long-term cost is significant. Child marriage can deepen intergenerational poverty, reduce tax contributions, increase dependency ratios and make it harder for countries to realise a demographic dividend. In this sense, ending child marriage is not only a rights and health imperative; it is also an economic policy issue. Africa cannot speak seriously about inclusive growth, women’s economic participation or human capital development while millions of girls continue to have their education, productivity and earning potential curtailed by early marriage.
We Must Eradicate Child Marriage—Absolutely
Child marriage is not a practice to be reduced, managed or made safer. It must be eradicated. Across Africa, millions of girls continue to have their education interrupted, their bodily autonomy constrained, their economic futures narrowed and their health placed at risk because of social norms, gender inequality, poverty and weak systems of protection. The consequences are neither temporary nor confined to childhood; they shape women’s health, economic security and agency across the life course and can reproduce disadvantage across generations. The designation of 27 November as the International Day for the Elimination of Child, Early and Forced Marriage should therefore sharpen our collective resolve. The question is no longer whether child marriage is harmful. The evidence is overwhelming. The task before African governments is to build the political, legal, social, economic and health-system conditions necessary to end it completely.
