What makes this research different?

Every figure on these pages updates automatically as our source data refreshes, nothing is hand-typed. The rankings draw on the HIFLD fire-station registry (DHS/CISA), USFA National Fire Statistics, FEMA AFG/SAFER grant disclosures, and 2023 US Census population estimates, so each result is auditable to the source row.
