How useful is the county proxy for ZIP 52218?
Within the participating-agency records for Linn County, reported violent and property crime rates both sit below their U.S. benchmarks: violent crime is 96% below and property crime is 97% 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 52218. 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.
52218 is comparatively spread out at about 23 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.
