About 25 per cent of women aged 18-29 and 15 per cent of men aged 21-29 got married before reaching the minimum legal age of marriage, according to the latest National Family Health Survey (NFHS) conducted between 2019-21.

In India, the legal age of marriage for women is 18 and 21 for men. However, the government is planning to make it 21 for both men and women.

The NFHS-5 said about two-fifths of women married before reaching the legal age in West Bengal (42 per cent), Bihar (40 per cent), and Tripura (39 per cent), and about one-third of them tied the knot before reaching the legal age of marriage in Jharkhand (35 per cent) and Andhra Pradesh (33 per cent).

The percentage marrying before the legal minimum age is 32 per cent in Assam, 28 per cent in Dadra & Nagar Haveli and Daman & Diu, 27 per cent in Telangana, and 25 per cent each in Madhya Pradesh and Rajasthan, the NFHS said.

The percentage of women marrying before reaching the legal minimum age of 18 is lowest in Lakshadweep (4 per cent); Jammu and Kashmir, and Ladakh (6 per cent each); Himachal Pradesh, Goa, and Nagaland (7 per cent each), and Kerala and Puducherry (8 per cent each).

Overall, 20-25 percent of men age 21-29 in Bihar (25 per cent), Gujarat, Rajasthan, and Madhya Pradesh (24 per cent each), Jharkhand (22 per cent), Arunachal Pradesh (21 per cent), and West Bengal (20 per cent) marry before the legal minimum age of 21 years.

The lowest proportions of men marrying below the legal age at marriage are in Lakshadweep and Chandigarh (less than 1 per cent), Kerala (1 per cent), Puducherry, Tamil Nadu, and Nagaland (4 per cent each), Karnataka and Andaman and Nicobar Islands (5 per cent each), Himachal Pradesh and Goa (6 per cent each), and Delhi, Punjab, and Maharashtra (9 per cent each).

But the report also said that early marriage has been declining over time.

"Marriage before the legal age of 18 is 23 percent for women age 20-24, compared with 47 percent for women age 45-49. Similarly, for men, marriage before the legal age of 21 years has dropped from 27 per cent for men aged 45-49 to 18 per cent for men aged 25-29," it said.

The median age at first marriage for women aged 20-49 slightly increased from 19 years in 2015-16 to 19.2 years in 2019-21. For men aged 25-49, the median age at first marriage slightly increased between 2015-16 and 2019-21 (from 24.5 to 24.9 years), the NFHS said.

It was also noted that women having 12 or more years of schooling marry much later than other women.

"The median age at first marriage for women aged 25-49 increases from 17.1 years for women with no schooling to 22.8 years for women with 12 or more years of schooling," it said.

The median age at first marriage for women aged 25-49 is higher among Jain women (22.7 years), Christian women (21.7 years), and Sikh women (21.2 years) than women from all other specific religions (18.7-19.7 years), the NFHS said.

Almost half of women with an abortion (48 per cent) sought their abortion due to an unplanned pregnancy. Sixteen percent of women with an abortion had complications from the abortion.

In 2019-21, 11 per cent of women age 15-49 have experienced a stillbirth, miscarriage, or abortion in their lifetime, compared to 12 per cent in 2015-16.

The same percentage (4 per cent each) of women aged 15-49 had a non-live birth in the five years preceding the NFHS-5 survey and in the NFHS-4 survey.

Eleven percent of marriages are consanguineous, which are more common in all of the southern states except Kerala.

Consanguineous marriages are women who report that their husband was related to them by blood before their marriage.

Teenage childbearing is higher among Muslim women age 15-19 years (8 per cent) than the other religious groups, the report said.

The survey also found that one in nine women age 45-49 are widowed.

The NFHS-5 survey work has been conducted in around 6.37 lakh sample households from 707 districts of the country from 28 States and 8 UTs, covering 7,24,115 women and 1,01,839 men to provide dis-aggregated estimates up to district level.

The national report also provides data by socio-economic and other background characteristics; useful for policy formulation and effective programme implementation.
