Geography Illinois (official worksite). Employees whose location OPM withheld are not included. Pay definition Annualized adjusted basic pay: base pay plus locality or special-rate supplement, after pay caps. Excludes bonuses, overtime, allowances and benefits. More Coverage
OPM published pay for 27,044 of 27,120 employees (99.7%).
Pay figures use the 25,620 full-time employees with published pay. Coverage details OPM withheld the duty-station location for 943,611 federal employees nationwide, including the entire Department of Defense civilian workforce and large parts of the Departments of Homeland Security and Justice. Those employees are not counted in any state, so state totals understate the federal presence, especially in states with large military installations.
