Rape in India has been described by Radha Kumar as one of India’s most common crimes against women and by the UN’s human-rights chief as a “national problem”. In the 1980s, women’s rights groups lobbied for marital rape to be declared unlawful, as until 1983, the criminal law (amendment) act stated that “sexual intercourse by a man with his own wife, the wife not being under fifteen years of age is not rape”. Marital rape is still not a criminal offence. While per-capita reported incidents are quite low compared to other countries, even developed countries, a new case is reported every 20 minutes. New Delhi has the highest rate of rape-reports among Indian cities. Sources show that rape cases in India have doubled between 1990 and 2008. According to the National Crime Records Bureau, 24,206 rape cases were registered in India in 2011, although experts agree that the cases of unreported sexual assault are higher.
