How useful is the county proxy for ZIP 19806?

Within the participating-agency records for New Castle County, reported violent and property crime rates both sit below their U.S. benchmarks: violent crime is 66% below and property crime is 70% below. The two submitted measures point in the same direction, but they do not establish complete county coverage or turn the result into a ZIP-level rating for 19806. Both comparisons use the same 2024 county reporting population and FBI-submitted counts, so the two directions are internally comparable for this release, not evidence about a different year.
