How we compute this
We aggregate ZipCheckup's per-ZIP Home Safety score — a composite of EPA drinking-water compliance, lead and copper readings, EPA radon zones, and FEMA flood exposure — into a national average and a per-state distribution. The figure recomputes each build from the latest federal extracts.
The score is a relative composite, not a regulatory determination. A state's average reflects the mix of ZIP scores within it; we publish the distribution side by side and draw no causal conclusion about why one state's mix differs from another's.
States are listed alphabetically, not ranked. A higher average does not certify safety, and a lower one does not certify harm — each ZIP carries its own underlying federal data, which the per-ZIP report shows in full.
