How we calculated this
Each police agency's crimes, as reported to the FBI, are spread across the census block groups it serves using population, jobs, points of interest and, where available, local incident records. Boulder's figures add up its 76 block groups. The index compares crimes per resident with the U.S. rate.
- Boulder's published incident records inform the estimate for every neighborhood.
- 38.4% of residents live in block groups whose estimate has high confidence (80% interval within about 5x).
- 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.
