Delhi is definitely the most unsafe place for women in India but if you are talking global then think again. According to the 2007 data, the latest available from the National Crime Records Bureau, Delhi with 3.57 rapes per 1,00,000 people is comparatively better then New York, safest city in the US, which recorded 10.48 rapes per 1,00,000 people.
When Indian metro cities were compared with other world cities like Los Angeles, it seemed that women are a lot safer in Indian cities. Los Angeles witnessed 27.3 rapes per 1,00,000 people in 2006.
According to the 2010 British Crime Record Survey, 4.2 percent British women above the age of 16 suffered rape or attempted rape at least once in their lifetime.
Even countries like Belgium, 29.5 per 1,00,000, and France, 16.4 per 1,00,000, had higher figures than Delhi, the most unsafe place in India for women.
Rape is definitely under-reported in India but this is as true for the United States. The perpetrators of more than one-third of total rapes in US happen to be family members and most of these go unreported, according to surveys and statistics.
The twin gangrapes, one in Kolkata of a 37-year-old and another one in Noida of a 17-year-old schoolgirl, have hit us hard but we should also understand that crimes against women and specially those related to rape and sexual abuse are a big problem for every city and every society.
