All New Jersey counties, annual
Official annual resident-population estimate; the series behind Census QuickFacts (fact PST045224). Values transcribed from the PEP Vintage 2024 county-level bulk file (co-est2024-alldata) filtered to STATE=34; the 21 counties sum exactly to the published state total of 9,500,851.

All 21 New Jersey counties; NJ resident deaths, all ages, 2020–2024
Residence-based (death-certificate) counts from NJ DOH Death Certificate Database (Office of Vital Statistics and Registry), via the NJSHAD Injury Mortality query module. Injury cause = Fire/Flame/Smoke per the NCHS ICD-10 external-cause-of-injury mortality matrix (exposure to smoke, fire and flames, ICD-10 X00-X09), all injury intents, all ages. No suppression: exact integer counts; county-year cells with zero deaths shown as 0. Per-year county counts sum exactly to the statewide totals (2020:59, 2021:75, 2022:57, 2023:77, 2024:57 = 325 over five years). Residence-based (vital-statistics) basis differs from fire-incident (NJFIRS) counts; NJ incident-based "Fire in New Jersey" was not current (latest 2016).
County incident sources
Population (Census) and civilian fire deaths (New Jersey Vital Statistics, NJ DOH) cover every county. Incident/response figures are published individually by 0 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.”
