Figures are nominal — not adjusted for inflation — because USAspending publishes them that way and adjusting them here would mean this site had edited a government figure. The per-resident figure divides by the 2020 decennial count, which is the population USAspending carries; a 2020 denominator against 2025 spending overstates per-head figures wherever a place has grown since. Mercer County ranks 140th of 3,233 on this measure in FY2025.
