If you are a girl educated and from an economically stable family from an urban area, either Jain, Christian or upper-caste Hindu, the chances are you will not be married before adulthood (18 years), according to a new report.
Some other highlights:
* Teen pregnancy is nine times higher among illiterate women than among those who have finished school.
* Women from cities marry two years later than rural counterparts; the richest women marry four years later than the poorest.
* Tribal Assam, which allows younger women to have sex outside of marriage, has a high age of marriage.
The age at marriage is mostly rising within the lower castes, but at a slower pace than within the upper-castes, indicates a seven-state report from Nirantar, a Delhi-based advocacy.
Jain women marry the last (at a median age of 20.8 years), preceeded by Christian women (20.6 years) and Sikh women (19.9 years). Hindu and Muslim women have the lowest median age at first marriage (16.7 years). Hindus and Muslims together account for 973 million, or 80 percent of India's 1.2 billion people, according to the 2011 census.
Teenage pregnancies and motherhood are higher for Hindus and Muslims (16 percent) than for any other religion, making clear the relationship between early marriage and teenage pregnancies.
What determines child marriage?
Family income, location (urban and rural), community, caste and education are directly correlated with an Indian girl's age of marriage, according to the Nirantar report -Early and Child Marriage in India: A Landscape Analysis.
Nirantar works especially with women from disadvantaged communities, and its report stresses the need to change attitudes, and the need to recognise and remove adolescents from the broad category of 'child'.
Although the data reveal the widespread nature of child marriage, it also showed the incidence of child marriage is dropping. Only 12 percent of Indian women who married before the age of 20 were younger than 15 at the time of marriage, according to the study.
Women have always had it worst
Nearly 17 million girls between the ages of 10 and 19 six percent of the age group are married, asIndiaSpend has reported, many to older men. This is an increase of 0.9 million from the 2001 census.
The legal age for marriage is 18, so some involved may have been adults, but it is unlikely both partners were. Of these married children, 76%, or 12.7 million, are girls, according to census data. Only four million boys in this age group are married, reinforcing the fact that girls are significantly more disadvantaged.
Uttar Pradesh, India's most populous state, leads the list of states reporting child marriage.
Globally, 720 million women were married before the age of 18, compared to 156 million men, a recent UNICEF report said. A third of these women are in India: about 240 million.
Education, income play lead roles in late marriage
Women in the highest family income bracket (this includes families that can afford all the 33 assets mentioned under a government wealth index) marry more than four years later than women in the lowest wealth quintile, according to data from the Nirantar report.
For women between 45-49 and 25-29 years, the gap in age at marriage between the highest and lowest wealth quintile widened from three and a half years, two decades ago, to five and a half years by 2007.
Among men, the age at marriage in the lowest wealth quintile is between 19.6 and 20.1 years of age, whereas among men in the wealthiest quintile, the age at marriage is between 25.3 and 26.6.
The percentage of women between 18 and 29 married by the legal age of 18 is 45.6 percent and the percentage of men between 21 and 29 married by the legal age of 21 is 26.6 percent.
If you live in a city, you marry later
Women from urban areas, on average, marry more than two years later than their rural counterparts, according to the Nirantar report.
The median age at marriage among urban women was 18.8 years, compared with 16.4 years among rural women. A quarter of all women aged 15-49 in urban areas have never been married, compared with 17 percent of rural women.
Among men aged 15-49, 42 percent in urban areas and 32 percent in rural areas have never been married.
Teen pregnancy nine times higher among illiterate women
Among educated women (with at least 12 years of education) in the age groups of 25-49, it was found that there is a seven-year difference in the median age at marriage compared to those women with no education.
The level of teenage pregnancy and motherhood is nine times higher among women with no education than among women with 12 or more years of education. About 258 million Indian women are illiterate, according to the 2011 census, down from 272 million from 2001.
Marriage was the main reason for six percent of girls in rural areas and two percent of girls in urban areas dropping out of school.
