The 15 Safest Towns to Live on Long Island

Based on the 5-year NY DCJS Index Crime baseline (2019-2023) blended with current 90-day activity, Syosset (Nassau County, pop. 19,000) ranks #1 safest with a composite score of 3.2 — anchored on a DCJS Index Crime rate of 4 per 1,000 residents. Index Crime tracks the 7 FBI Part I offenses (murder, rape, robbery, aggravated assault, burglary, larceny, motor vehicle theft); other categories like DWI and drug possession are not included in this number.

Composite score = 0.80 × DCJS Index Crime baseline + 0.20 × current 90-day signal. The baseline is the NY Division of Criminal Justice Services 5-year average (2019-2023) Index Crime rate per 1,000 residents, sourced from official DCJS Uniform Crime Reporting submissions by Nassau County PD, Suffolk County PD, and all incorporated village PDs (Hempstead, Freeport, Garden City, Amityville, Patchogue, etc.). For hamlets covered by NCPD or SCPD rather than their own village PD, we infer hamlet-level rates from precinct-level DCJS data — less precise than the measured village-PD numbers, and flagged in the per-town card. The 20% recent-signal weight reflects current activity from our 90-day enriched-article pipeline (NYSP, NCPD, SCPD, News 12, Patch, Newsday, Daily Voice) so the ranking captures recent shifts without being dominated by news-cycle volume. Full editorial formula and source code are published below.

Because reporting volume isn't safety. Some towns get heavy press-release coverage from their patrolling agency (SCPD's 3rd Precinct produces hundreds of public reports per month covering Brentwood, Bay Shore, Central Islip); others get almost none (NCPD's 3rd Precinct covers Manhasset, Port Washington, Roslyn — wealthy North Shore towns where most policing happens quietly and below the press-release threshold). A pure 90-day count would tell you which agencies write press releases, not which towns are safer to live in. Anchoring 80% of the score on DCJS Index Crime fixes that — the multi-year UCR data is the same dataset the FBI publishes in its annual Crime in the U.S. report, and it reflects what was reported to police regardless of whether the police chose to issue a press release.

It's anchored on the official NY DCJS Index Crime data (the same numbers the FBI publishes in Crime in the U.S.), so the baseline ranking is the official multi-year safety signal. The 20% recent-signal layer is our own editorial methodology and not endorsed by DCJS or any government agency. For relocation decisions, use this ranking AND look up the most recent annual DCJS data for the specific town at criminaljustice.ny.gov — they publish individual agency-level reports every June for the prior calendar year.

DWI events are weighted ×2 in our formula — lower than burglary (×3) or assault (×5) — because DWI is a driving-behavior signal, not a neighborhood-safety signal. Counting DWI arrests equal to a homicide would distort the rankings against towns with a busy commuter parkway running through them (the Southern State, the LIE, etc.), making those towns look "more dangerous to live in" when really they're just "more trafficked by commuters from elsewhere who got pulled over locally". If you're specifically evaluating DWI risk for your commute, see our DWI Court Watch hub instead.

Every 2-4 hours. The longislandtraffic.com autopilot pipeline re-ingests police feeds, news outlets, and 511NY data on a tiered schedule (every 4 hours normally, every 2 hours during active news cycles, every 30 minutes during severe weather). Each rebuild recomputes the safety scores from the latest 90-day window. So the version of this report you read today may differ from one a week from now — the underlying data is a rolling snapshot, not a year-over-year fixed dataset.
