West Bengal is progressive. Why does child marriage say otherwise?

West Bengal has long projected an image of social progress: a state shaped by women’s education, a relatively early demographic transition and a political vocabulary of female welfare. Yet when it comes to child marriage, the numbers tell a far less comfortable story.

The latest National Family Health Survey shows that the proportion of women aged 20–24 in West Bengal who were married before 18 fell from 41.6% in NFHS-5 (2019–21) to 36.4% in NFHS-6 (2023–24). That is meaningful progress, but it remains dramatically above the national figure of 20.1%.

The more recent Sample Registration System data makes the contradiction harder to dismiss. Among women who married in 2024, 6.3% in West Bengal were below the legal marriage age of 18 — the highest proportion among the bigger states and Union territories, against 2.1% nationally. Bengal also recorded 7.6% in urban areas, compared with 1.1% nationally. In rural Bengal, the figure was 5.9%.

That urban figure matters. It makes it difficult to explain Bengal’s child-marriage problem simply through rural poverty or lack of schooling.

And Bengal has not lacked policy interventions. Kanyashree Prakalpa, launched in 2013, was explicitly designed to keep adolescent girls in education and delay marriage through conditional cash transfers. The scheme became internationally recognised, including through a UNESCO public-service award. Yet the persistence of early marriage raises a more difficult question: can financial incentives change a practice whose roots are social as much as economic?

Research complicates the picture further. A 2026 study of marriage patterns across West Bengal’s districts found that the timing of marriage varies considerably within the state. Urbanisation was associated with later marriage, but female literacy and work participation did not show statistically significant independent associations with marriage timing in its district-level analysis. The implication is important: education may be necessary, but it cannot by itself explain when a girl is allowed to remain unmarried.

The district-level data expose the same unevenness. NFHS-6 brought the state average down, but Murshidabad remained almost unchanged, with 55.1% of women aged 20–24 reported as married before 18, compared with 55.4% in NFHS-5. South 24 Parganas, meanwhile, moved backwards, from 41.9% to 46.9%.

And the problem extends beyond Murshidabad. Earlier district-level analysis of NFHS data found particularly high prevalence in rural Murshidabad and Birbhum, while other districts — including Darjeeling, Jalpaiguri and Howrah — recorded substantially lower levels. The spatial variation matters because it suggests that there is no single “Bengal model” of child marriage; the determinants differ across social and economic landscapes.

The Sundarbans adds another layer to that geography. A 2026 ground-reporting study on child marriage in the delta found that climate-induced disasters, displacement and economic insecurity can intensify vulnerability. In Gosaba block alone, 76 cases were officially recorded between 2024 and 2025, although the report cautions that official figures may capture only a fraction of the incidence. The report also documents concerns over adolescent girls migrating from vulnerable islands and blocks after disasters, increasing exposure to trafficking and coerced marriage. These are field-report findings, rather than state-wide prevalence estimates, but they show how environmental insecurity can compound existing gender and economic vulnerabilities.

That vulnerability is not confined to remote islands. In September 2026, police in Kolkata arrested three people — including the father, husband and mother-in-law of a minor from South 24 Parganas — in a case involving child marriage, abduction and alleged sexual abuse. The investigation began after an NGO alerted police. The case also revealed how a welfare payment intended for the girl had become part of a family dispute surrounding the marriage. It is an individual criminal case, not evidence of prevalence, but it illustrates the gap that can exist between welfare delivery and a girl’s actual control over her life.

Yet Murshidabad also offers a counterpoint. Local authorities have begun declaring individual gram panchayats child-marriage-free, while community and administrative interventions have reportedly stopped hundreds of proposed marriages. In November 2025, the district administration said more than 1,000 child marriages had been prevented in five months.

That suggests the problem is not simply that Bengal lacks schemes. It is that policy penetration and social transformation are not the same thing.

The persistence of child marriage reflects the interaction of household insecurity, gendered expectations, social norms, marriage markets and the perceived economic or social cost of keeping girls unmarried. A 2026 study on West Bengal similarly found that low educational attainment and dropping out of school remain important drivers, while arguing that structural and normative constraints require interventions beyond simply expanding girls’ education.

The UN’s decision to designate November 27 as the International Day for the Elimination of Child, Early and Forced Marriage now gives that contradiction a global frame. The date marks the launch of India’s Bal Vivah Mukt Bharat campaign in 2024.

For Bengal, the question is more uncomfortable than whether the numbers are falling.

Why, after years of education and welfare interventions, does the right to decide when a girl marries remain so unevenly distributed?
