Every October 11, the world pauses to listen to girls, not only as dependants to be protected, but as citizens with dreams, rights and the capacity to lead. This year’s International Day of the Girl Child carries a message Nigeria cannot afford to ignore: “End Child Marriage and Invest in Girls’ Rights.”

For millions of Nigerian girls, the day is more than a global observance, it is a reminder that childhood should be spent learning, playing and growing, not preparing for marriage, motherhood or a future decided by poverty and tradition.

Nigeria remains home to more than 24 million child brides, and about three in 10 young women were married before turning 18. Although national prevalence has fallen from 44 per cent to around 30 per cent, progress remains slow and deeply unequal.

In the North-East and North-West, prevalence approaches 50 per cent, showing that geography and household income still determine whether a girl remains in school or is pushed into early marriage.

Child marriage is not simply an early union, it is a denial of a girl’s right to safety, education, health and self-determination. Girls who marry early are more likely to leave school, face complications during pregnancy and childbirth, experience violence, and become trapped in a cycle of poverty.

The connection between education and marriage is striking. Among Nigerian women aged 20 to 24 who married before 18, 81 per cent had no formal education, compared with 19 per cent of those who attained at least secondary education. In other words, every year a girl remains in school is a year her choices, confidence and future expand.

Nigeria’s out-of-school crisis remains one of the biggest barriers to protecting girls. UNICEF estimates that 7.6 million girls are out of school, including 3.9 million at primary level and 3.7 million at junior secondary level. The problem is especially severe for girls from poor households as only 26 per cent from the poorest attend secondary school, compared with 81 per cent from the richest group.

When school fees, insecurity, early pregnancy and domestic responsibilities combine, many families see marriage as the only available solution for a girl child

Nigeria has laws meant to protect children, but protection on paper is not the same as protection in practice. The Child Rights Act prohibits child marriage, yet loopholes and uneven adoption across states continue to leave many girls exposed.
Only 26 states had adopted the Act at the time of UNICEF’s assessment, while provisions against child marriage were yet to be fully incorporated into some state laws. Until enforcement becomes consistent, prosecution becomes real, and communities are engaged rather than merely warned, girls will continue to pay the price for legal gaps.

The 2026 theme is not only a call to stop a harmful practice, it is a demand to build a better future for girls. That means safe schools, menstrual-health support, access to healthcare, protection from abuse, vocational and digital skills, and opportunities for girls to lead.

It also means changing mindsets. Parents, religious and traditional leaders, teachers, policymakers and boys all have a role to play in challenging the belief that a girl’s value ends at marriage. Keeping girls in school, especially at secondary level, is strongly linked to delaying marriage and expanding life choices.

Nigeria cannot build a prosperous future while sacrificing its girls. A girl who is educated, healthy, protected and free to decide her own path becomes a stronger worker, leader, mother and citizen.

The International Day of the Girl Child should therefore be more than a day of speeches. It should be a renewed national commitment to end child marriage, enforce child-protection laws, fund girls’ education and listen to girls themselves. Their rights are not a favour to be granted.

They are the foundation of Nigeria’s future.
