Florida's Gulf Coast Leads the Country
Nine Gulf Coast Florida counties appear across this ranking — more than any other region — and the top of the list is theirs. Collier County (Naples) has cut its homicide rate by 52% since 2015, from 4.6 to 2.2 per 100,000 residents. Lee County, the Fort Myers metro at 800,000 people, dropped 40%. These aren't small-sample flukes: every county on this list met a minimum incident threshold before we counted its trend as real. Florida's Gulf Coast is the most statistically credible safety turnaround story in large-county America over the past decade.
The Entire New York Metro Is Moving in One Direction
Brooklyn, Queens, Staten Island, and Manhattan all appear in the top 50, as do Nassau, Suffolk, Westchester, and Orange counties in the outer ring. Kings County (Brooklyn) alone covers 2.6 million people and is down 35% since 2015, starting from a baseline of 7.8 per 100,000. The improvement isn't one borough or one suburb — it's the metro as a whole, which makes it harder to attribute to any single policy or accident of geography. Whatever is happening in greater New York, it's happening broadly.
California Shows Up Despite Its Reputation
Stanislaus County (Modesto) leads the California entries at #6, down 40% from a 6.5 baseline — a genuinely elevated starting point. Contra Costa, San Mateo, San Francisco, and Alameda all follow. Even Los Angeles County, at 9.8 million people, appears at #49 with an 11% decline — the smallest improvement on the list, but one backed by tens of thousands of data points. California's crime reputation is largely shaped by property crime and car break-ins; on homicide specifically, its large Bay Area and Southern California counties have been trending in the right direction for a decade.
