How the town pages are chosen
One page per municipality in Connecticut, Massachusetts, New Jersey, Pennsylvania and Rhode Island, and one per place in Florida, wherever the advertising network’s list of ZIP codes reaches. A municipality gets a page when more than half of its 2020 land area lies in those ZIP code areas, it has at least 1,000 residents and at least 15% of its occupied homes are owner-occupied. Hail counts are reports of hail 1 inch or larger within 10 miles of the place’s internal point from the Census gazetteer, 2006 through 2025. Data built 2026-10-24.
