Recently the National Crime Records Bureau put out statistics of violent crime in India in 2012. In this post we will look at the incidence of rape in various states.
The following chart plots the number of rapes per 10000 people against the number of murders per 10000 people. The reason we have included the murder numbers here is to control for states which have an overall high rate of violent crime. This chart also has the regression line and the shaded region is the 95% confidence interval around this line.
It is interesting to note that relative to murder rate, Mizoram has the highest case of reported rape in India. In fact, Mizoram has the absolute highest rape rate in India. However, we need to take into account that these are the numbers of reported rape cases. According to reports in the media, a large number of rape cases in India go unreported. So these numbers need to be taken with a handful of salt.
Instead of the Y-axis to be rapes per 10000 persons, make it rapes per 1000 women (or 10000 women) and then plot. This will take into consideration states that have poor sex ratio (as they will have lesser # of rapes, while the % of rapes may be high).
