New York's murder rate has fallen 88% since 1990 and is still more than three times London's

In 2025 New York had 3.6 murders per 100,000 residents, the highest of five big cities and more than three times London's 1.1, after falling 88% since 1990.

The NYPD reports its fewest murders on record for the first nine months of 2026, a record count rather than a record rate. New York's 2025 rate was still the highest of five big cities. Will this year's fall narrow the gap with London?

How articles work

  • Reproducible. The numbers in an article are computed by its code from its companion dataset — not typed in.
  • Sourced. Every figure quoted from elsewhere links to the table it came from, with its vintage and margin of error.
  • Labelled. Each number says whether it was measured in one survey, estimated across two, or assumed — and every chart says what it cannot show.
  • Interactive. The charts can be filtered and re-cut in the browser; every combination they can reach was computed in advance from the data, with its margin.
