Child marriage is one of those problems on which India has made real, measurable progress — and still has a long way to go. In a generation, the practice has roughly halved, yet it continues to shape the lives of nearly a quarter of young women, cutting short their education, endangering their health, and locking families into cycles of poverty. This guide sets out the law, the loopholes, why child marriage persists, and what is working to end it.
The trend: a real decline
The direction of travel is genuinely encouraging. According to national survey data, the share of women aged 20–24 married before the age of 18 has fallen from about 47% in 2005-06 to 26.8% in 2015-16 and around 23% in 2019-21. That is a dramatic change in a short time. But the same figure means nearly one in four young women is still married as a child, with rates far higher in certain states and among poorer, rural and less-educated families. Progress is real, but uneven and incomplete.
What the law says
The core law is the Prohibition of Child Marriage Act, 2006 (PCMA), which sets the minimum legal age of marriage at 18 for women and 21 for men and provides penalties for those who perform, promote or permit a child marriage. A key limitation is that a child marriage is often treated as 'voidable' — valid unless the underage party seeks to annul it — rather than automatically void, which weakens deterrence. A bill to raise the legal age of marriage for women to 21, aligning it with men, has been debated. Alongside PCMA, other laws on violence and child protection apply.
Why it persists: the real drivers
Child marriage is rarely about the law and almost always about circumstance:
- Poverty — a married daughter is one less mouth to feed and, with dowry, an earlier and sometimes cheaper obligation.
- Limited education and opportunity — where girls cannot study or earn, marriage becomes the default path.
- Social norms and pressure — community expectations and the value placed on early marriage.
- Safety and 'honour' — families marry girls young out of misplaced fears about their security and reputation, sometimes worsened by a lack of safe schools.
The through-line is that child marriage flourishes where girls have few alternatives — which points directly to the solution.
The harm it causes
The consequences ripple across a lifetime. Child marriage ends education, often just as a girl reaches secondary school; it leads to early and frequent pregnancy, with serious health risks for both mother and baby and links to child malnutrition; it leaves young wives with less power in their households and a higher risk of domestic violence; and it passes disadvantage to the next generation. Ending child marriage is therefore one of the highest-leverage actions for health, education and gender equality at once.
What works
The evidence points clearly to a few levers:
- Keeping girls in school — the single strongest protection; every extra year of schooling lowers the risk.
- Economic support — conditional cash transfers and scholarships that make keeping a girl in school worthwhile for the family.
- Awareness and community engagement — changing norms, working with families, and empowering girls to know their rights.
- Enforcement — a functioning system that treats child marriage as the offence it is, including responsive child-protection services.
What you can do
- Support girls' education and child-rights NGOs, especially those keeping adolescent girls in school.
- Report child marriages — the childline service (dial 1098) can intervene.
- Challenge the norms in your own community that treat early marriage as acceptable.
- Sponsor a girl's schooling — education is the most durable prevention.
Child marriage is not an unchangeable tradition; India's own recent progress proves it can be reduced quickly when girls have education and opportunity. Finishing the job means reaching the families and regions still left behind. To support organisations working to end child marriage, find verified NGOs on NGOLists.
