How this page is built. Figures come from the official statistical releases linked above; where agencies publish provisional numbers we say so, because they are revised. Many Indian statistics are compiled state by state and published a year or two late (NCRB’s accident report for 2024 came out in 2026), so we say which year each figure covers. Large numbers are written in international form, with lakh (100,000) and crore (10 million) in brackets where Indian sources use them. Photos are public-domain or Creative Commons images credited in each caption; file photos are illustrative and are not from the events described unless the caption says so. This page tracks trends and is not personal safety, medical, legal or financial advice.
