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. Lake San Marcos's figures add up its 3 block groups. The index compares crimes per resident with the U.S. rate.
- Lake San Marcos's published incident records inform the estimate for every neighborhood.
- 0.0% of residents live in block groups whose estimate has high confidence (80% interval within about 5x).
