How useful is the county proxy for ZIP 56566?
Participating agencies give Mahnomen County a split reported profile: violent crime is 99% above the U.S. benchmark while property crime is 63% below it. A single "high" or "low" label would hide that difference; the submissions neither establish complete county coverage nor identify conditions within ZIP 56566. 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.
56566 is comparatively spread out at about 46 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.
