What the records show

Department analytics

Median pay and headcount show where payroll dollars concentrate and which agencies define the jurisdiction’s compensation profile.

Largest departments

The 12 departments employing the most people in 2018. Bar length is headcount. These departments drive most of the payroll and set the overall pay mix.

Highest-paying departments

Departments ranked by median total compensation — the typical employee's pay. High medians usually signal specialized or professional workforces (e.g. medical, legal, or public-safety agencies) rather than across-the-board higher pay.
