Caterpillar's real, continued regional presence

Caterpillar's global headquarters left Peoria for Deerfield, Illinois in 2017 (and later for Irving, Texas in 2022), but the company still employs roughly 12,000 people across the Peoria area -- the largest concentration of Caterpillar employees anywhere in the world.

Healthcare: the region's largest, fastest-growing sector

Healthcare now accounts for roughly 18% of regional jobs versus manufacturing's roughly 13%, anchored by OSF HealthCare's own downtown-Peoria headquarters (a repeat Forbes best-employer honoree) and UnityPoint Health.

A real, mixed near-term outlook

Regional economic reporting reviewed this pass described Peoria's economy as remaining generally stable, with some disclosed uncertainty in the heavy-machinery manufacturing sector that many of the region's higher-wage jobs still depend on.
