Crime in Killingly, Connecticut

Updated ·Vorp Labs

The model puts major crime in Killingly at 82% below the U.S. rate per resident: 91% lower for persons crimes and 81% lower for property crimes. Expected major crimes are down 15.1% from a year earlier.

Where these numbers come from

The estimates start from what police agencies report to the FBI, modeled across Killingly's 14 census block groups for 18,339 residents. How Connecticut residents' crime totals reach the FBI: detailed incident reports for 86.3% and no reporting agency of their own for 13.7% (shares of 2020 residents). Sources · Method

Why other sites show different numbers for Killingly:
  • Year: many show an agency's last full FBI year (often two years back). These figures are the model's estimate for the current year, release 2026-11-10.
  • Crimes counted: some add simple assault, vandalism or drug offenses to "violent" or "property" crime; here major crime is persons plus property crime, and social disorder is separate.
  • Area: an agency's totals cover its jurisdiction, which can differ from the city's limits; these are summed over the block groups inside Killingly.
  • Scale: a grade or a 1-to-100 score ranks places against each other; a rate per 1,000 residents and an index against the U.S. rate don't.

How we calculated this

Each police agency's crimes, as reported to the FBI or estimated where it didn't report, are spread across the census block groups it serves using population, jobs, points of interest and, where available, local incident records. Killingly's figures add up its 14 block groups. The index compares crimes per resident with the U.S. rate.

  • Killingly has no published incident records in our data, so its estimate relies on agency totals and neighborhood characteristics.
  • Rates are per resident, so places where many people work or visit but few live, such as downtowns, airports and stadiums, can read high.
  • Disorderly conduct and trespassing are modeled, because the FBI records them only through arrests.
  • Residents: 18,339. Model updated Nov 10, 2026. Release 2026-11-10
