How useful is the county proxy for ZIP 59639?

Within the participating-agency records for Lewis and Clark County, reported violent and property crime rates both sit below their U.S. benchmarks: violent crime is 65% below and property crime is 80% 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 59639. 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.

59639 is comparatively spread out at about 2 people per square mile. That settlement pattern may differ sharply from the county's population centers, another reason to use the county rates as regional context rather than a local estimate.
