On the 3 of 12 dimensions that carry measured values today, radon differs — 25401 is Zone 1, 26101 is Zone 2 (lower is less predicted potential); 2025 median air quality is Good in both (AQI 39 vs 39); health-based water violations in 3 years — 0 for 25401, 2 for 26101. zipradar names no overall winner: the other 9 dimensions are not populated yet, and these three are county-level indicators rather than address-level readings.
