How useful is the county proxy for ZIP 54307?

Within the participating-agency records for Brown County, reported violent and property crime rates both sit below their U.S. benchmarks: violent crime is 93% below and property crime is 85% 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 54307.
