About the County

Known as the Heart of Illinois, Peoria County is at the center of a multi-county region along the Illinois River. It has a population of 181,830 (census 2020). Peoria County encompasses 629 square miles, running 32 miles north/south and 28 miles east/west.


The Greater Peoria region has a diverse and vibrant business base and is home to a variety of firms that focus on innovation, research, and development. While agriculture and the manufacturing giants of Caterpillar and Komatsu still have a firm presence, the region’s industries over the last 10 years have noticeably expanded and grown to encompass healthcare, education, banking, biotech, and craft distilling, among others. 

The thriving economic base is anchored by our booming medical community. OSF HealthCare and UnityPoint Health are both major employers in the region. Specialty care centers and providers abound. The University of Illinois College of Medicine and Jump Simulation Center are both located in Peoria as well as multiple colleges of nursing. 

The river continues to be a great economic driver in the County. It carries in excess of 39 million tons of freight each year. It recently became part of the federally recognized Heart of Illinois Regional Port District, which aims to bring more investment into the area.

The river bluffs slowly transition into prairie-like terrain that supports rich farm ground and agricultural operations in the central and western portions of the County. Roughly 250,000 acres are devoted primarily to corn, soybeans, cattle, hogs, and vegetables. We are also home to the USDA's National Center for Agricultural Utilization Research Lab, blending our roots in agriculture with our innovative future.

Many organizations, including Peoria Innovation Alliance, Distillery Labs, and Startup Greater Peoria, are investing in innovation and entrepreneurship in our region to continue to grow diversification efforts. Firms such as Natural Fiber Welding, which blends high fashion with plant-based manufacturing, and Bump Boxes, which curate and ships pregnancy-friendly products nationwide, are choosing Peoria County as their home.

Large and small concert and theatre venues, such as the Peoria Civic Center, Three Sisters Park, and Betty Jayne Brimmer Center for the Performing Arts, are active and flourishing. Cultural festivals filled with food and music are summer mainstays throughout the County. 

The city of Peoria, which is the County’s population and commercial center, has sports that any metropolitan area of similar size would envy, including a minor league baseball team affiliated with the St. Louis Cardinals, NCAA Division One athletics at Bradley University, and the Rivermen hockey team. Youth athletics are plentiful, from recreational play to travel and competitive leagues both within and outside of the local school districts. Peoria is also home to the Louisville Slugger Sports Complex, which hosts many regional and national youth sporting events and tournaments.

The County's landscape lends itself to a plethora of outdoor activities. Abundant public and private golf courses, substantial regional trail systems, fishing and hunting opportunities, a lively running scene, and mountain biking can all be found in the County.

The County encompasses 18 public school districts, with higher-than-average national graduation rates. In addition, many private schools are located in the County, both secular and with religious affiliations. Those homeschooling their children will also find active support networks in our region.

The region is also characterized as one with small-town friendliness and charm. Multiple communities are nestled along the majestic Illinois River, which flows along the entire eastern border of the County. These tight-knit communities are great places to put down roots, and charming small shops and restaurants encourage regional day trips for County residents and visitors alike.

Peoria County is governed by countywide elected officials and an 18-member Board elected by districts to staggered four-year terms.
