Every value in the Maryland Fireground Index traces to one of these authoritative public sources. Click any source to verify it yourself.
U.S. Census Bureau
Visit source ↗Population Estimates Program (PEP), Vintage 2024 (July 1, 2024) · 2024
All U.S. counties and county-equivalents, annual
Official annual resident-population estimate; the series behind Census QuickFacts (fact PST045224). Values transcribed from the Maryland Dept. of Planning reproduction of PEP V2024 (Demographic Trends Report 2020-2024, Table 3); the 24 county-equivalents sum exactly to the published state total.

Visit source ↗2024 Annual Fire Fatality Report — County Totals 2020-2024 · 2024
All 24 Maryland county-equivalents, annual (2020-2024 provided)
Fire-investigation basis (fatal-fire incidents), un-suppressed county breakdown. The 24 counties sum to the statewide 2024 total of 73. Differs from CDC/vital-statistics (death-certificate) counts.
County incident sources
Population (Census) and civilian fire deaths (MD State Fire Marshal) cover every county. Incident/response figures are published individually by 7 counties, each with its own definition and reporting year — those county sources are cited on each county's evidence profile. Counties without a public incident source are shown honestly as "Data not publicly available."
