Which is India’s safest city? The 2021 Crime in India (CII) report published by the National Crime Records Bureau (NCRB) shows that Kolkata had the lowest crime rate among 19 major cities in India, and Delhi had the highest. Crime rate is the number of criminal incidents reported in a year per million of the population. The actual picture, to be sure, could be very different from what the headline crime rate numbers suggest. Here are charts that explain this
2) ...but this needs to be read with a caveat on population...
Calculation of crime rates requires availability of up-to-date population figures. India conducted its last census in 2011, and the 2021 census has been delayed without any clarity on when it will be conducted. While the CII report does a relatively better job at estimating crime rate at the all-India and state-wise level – it takes population projections for the year – the city-wise estimates are pretty obsolete. Because there are no population projections at the city level, even the 2021 crime rate for cities is based on 2011 population estimates. This means that the population numbers are largely underestimates, which means that the crime rate numbers are likely to be overestimates. What makes the city-wise rate even more unreliable is the fact that they have shown very different trajectories of population growth in the decade between 2001 and 2011.

As is the case with official statistics, crime numbers also only capture what enters the official records. This means that cities which are proactive in filing cases will tend to show a higher crime rate. As is well-accepted among experts, both the attitude of law enforcement towards recording crimes as well as the inclination to report a crime to the police can affect this. While there’s no conclusive way to prove whether or not these factors have an impact on the numbers, a look at crime rates for different kinds of crimes shows a pattern which supports the argument that reporting and recording may have a role in determining crime rates. For example, while these cities show a small divergence when it comes to crime rate for murder (which is very unlikely to be not recorded or reported), the spread is many times larger for a crime such as rape (where the scope for non-reporting is much larger).

CII also gives information on charge-sheeting (the filing of charges before a court) rates across cities, offering a view on the efficiency of the police in disposing registered criminal cases. It is defined as the share of cases charge-sheeted by the police out of total cases disposed by them.A comparison with the previous years indicates a rise in the overall charge-sheeting rate in 19 cities to 67% in 2021, from 57% in 2019, but this number is three percentage points lower than what it was five years ago (70% in 2016). What is more alarming is the fact that Delhi, the city with the highest crime rate in 2021, has the lowest charge-sheeting rate (34.1%) in 2021. However, this is not the case for other cities with high crime rates. Surat, with the second-highest crime rate in 2021, has the highest charge-sheeting rate at 98% in 2021. And Kochi, with the third-highest crime rate, has charge-sheeting rate as high as 97.7% in 2021.
