How useful is the county proxy for ZIP 29570?

Participating agencies give Marlboro County a split reported profile: violent crime is 41% above the U.S. benchmark while property crime is 20% below it. A single "high" or "low" label would hide that difference; the submissions neither establish complete county coverage nor identify conditions within ZIP 29570. 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.

29570 is comparatively spread out at about 84 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.
