Summary
In general, police and firefighter budgets move in tandem. Despite decreases in crime, police outlays have increased; despite the number of fires decreasing in most of our cities, fire outlays have increased. Median household incomes and median home prices are positively correlated with police and firefighter salaries and fairly uncorrelated with FTEs. Police salaries have gone up as crime has gone down, and firefighter salaries have increased more in places with larger decreases in fire counts.
Context on Salaries: Wages across all occupations increased 1.9% in real terms from 2001 to 2019 according to the BLS OES. Police wages, from the same survey, increased 9.6% from 2001 to 2019, whereas police salaries (includes overtime and bonuses) for our list of 80 large cities increased 21% from 1999 to 2019. Meanwhile, firefighter wages increased 0.8% from 2001 to 2019, whereas firefighter salaries increased 19% from 1999 to 2019.

Fire Trends and Different Cuts of Data
Overall takeaway: generally, fires have remained relatively flat in most cities, with some decrease in many cities. This document explores multiple cuts of this.
The above scatterplots used Cut 2: All Fires (100 codes).
List 1
Cut 1: All Incidents
Cut 2: Fire Incidents Only (100s codes)
Cut 3: Building Fires only (111 Code)
Cut 4: Building Fires with no aid given or received only
Cut 5: Building Fires with no Aid received (but maybe aid given)
