The survey, which was carried out in all states in India, asked "ever-married" women whether they were married to someone from the same caste, or to someone from a higher caste, or to someone from a lower caste.
Uchunguzi huo, uliofanywa katika majimbo yote nchini India, uliwauliza "wanawake ambao hawajafunga ndoa" kama walikuwa wameolewa na mtu wa tabaka moja, au mtu wa tabaka la juu, au mtu wa tabaka la chini.
