8 ZIP codes · Avg score 91/100 · Grade A

ZipCheckup grade for Iberville Parish: A.

Checked records flag no major concern; missing data is unknown.

Iberville Parish earns an A or B, the top two of ZipCheckup's five grades, based on the average composite Home Safety Score of its scored ZIP codes. That composite can draw on drinking water records, radon zones, PFAS monitoring and air quality data, so a strong grade summarizes several sources and is not a reading from anyone's tap. Scores also vary from one ZIP code to another, and the 8 ZIP reports listed for the parish show where each one stands.
