Updated ·Vorp Labs
The model puts major crime in Swansea at 40% below the U.S. rate per resident: 52% lower for persons crimes and 37% lower for property crimes. Expected major crimes are down 7.3% from a year earlier.
- Modeled from FBI crime data for the police agencies serving Swansea. Where an agency didn't report to the FBI, its totals are estimated from its past reports or similar agencies.

- By the model's major-crime rate per resident, Swansea is higher than 48% of the 193 other Massachusetts places and lower than 49% of the 8,446 other places nationwide on CrimeMetric.
Where these numbers come from
The estimates start from what police agencies report to the FBI, modeled across Swansea's 11 census block groups for 17,782 residents. How Massachusetts residents' crime totals reach the FBI: detailed incident reports for 98.4%, summary counts only for 0.2% and no reporting agency of their own for 1.3% (shares of 2020 residents). Sources · Method
- 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 Swansea.
- 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.
Rates are the model's estimates of reported crime per 1,000 residents a year. Index: 100 is the U.S. rate per resident; 200 is twice it. How we calculated this

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. Swansea's figures add up its 11 block groups. The index compares crimes per resident with the U.S. rate.
- Swansea 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: 17,782. Model updated Nov 10, 2026. Release 2026-11-10
