Ionia County

Located in the west central portion of Michigan’s lower peninsula, Ionia County is a diverse mix of agricultural strength, manufacturing knowledge, natural resources, and strong communities.


The 2010 Census shows Ionia County’s population at 63,905.  This is a 3.9 percent increase from 2000.  The City of Ionia is the largest community within the County, with 11,394 residents.  The City of Belding, with 5,757 residents, and the City of Portland, with 3,883 residents, are located in opposite corners of the County.  Ionia County also has seven villages, ranging in population from 351 (Hubbardston) to 2,018 (Lake Odessa).  And the County has 16 townships, which range in population from North Plains Township with 928 residents to Boston Township with 4,384.


Ionia County was formed in 1831 from portions of Mackinac County and open territory, and was named after Ionia, a region in Greece.  With its rich history of multi-generational farming, much of the County remains rural and agricultural.  The County’s villages and smaller cities have preserved much of the historic charm and infrastructure that appeals to both residents and visitors. 


At the same time, the County offers a variety of attractions, including thriving retail and service areas centered on the downtown districts of its cities.  The County also has numerous outdoor recreation opportunities, including Bertha Brock Park, Green View Point Park, and the Ionia Recreation Area.  The Grand River, which meanders through the middle of the County, provides recreation adventures like boating and sport fishing.  The County and the City of Ionia also host the Ionia Free Fair, the largest free fair in the country.  That fair can trace its history back to 1857, when the first Ionia District Fair opened its gates.


The Orchard View Industrial Park, located near the City of Ionia, is the County’s principle industrial park.  The City of Belding also has a Renaissance Zone centered on the Belding Business Center.  The Ionia County Economic Alliance (ICEA) was developed by the area’s business community, and addresses economic development in the County by providing services aimed at recruiting and maintaining businesses within the County.   Since 2012, ICEA has partnered with The Right Place to continue to promote and advance the County’s economy.  Major employers in Ionia include the Michigan Department of Corrections, Meijer Inc., Ionia County Memorial Hospital, and the Herbruck Poultry Ranch Inc.


Ionia County is well served by transportation routes.  The major north-south route is M-66, running through the heart of the County.  The major east-west routes include I-96, running through the southern half of the County and M-21 through the center portion.
