The data on the wikipedia page raises a question. It shows that the number of rapes per 100 000 is about 1/4th that of the US.

Now I assume a lot of that is due to unreporting, but is rape really that much more common in India? Anecdotal evidence suggest it is.

It reminds me of crime in Canada vs. the US. The US has almost 10x the population, so if you think about something like school shootings (of which there have been quite a few in Canada), you'd expect 10x of them in the US.
