Sullivan is "small town America" and were proud of it. With a population of 4326, Sullivan is the county seat of one of the smallest counties in the State of Illinois, Moultrie. Dont let our agricultural surroundings fool you into thinking this is simply a farming community. Yes, farming is a big part of who we are, but there is so much more. Sullivan contains a beautiful little downtown square with a historic courthouse, which is often the hub of activities when our own Little Theatre on the Square is in season. Several downtown restaurants serve a variety of food and retail shops are continuing to open. Major industry is represented by two large manufacturers who contribute substantially to keeping unemployment low. Several mid-sized firms and small home-grown businesses help maintain the well rounded diversity of our sales tax base. Sullivan has excellent schools and beautiful homes within city limits or in nearby rural settings. The safety of the community makes it an ideal place to raise a family as kids can easily walk or ride bikes to the public parks or pool. Visitors may enjoy outdoor recreation at the nearby 11,000 acres of nature and 200 miles of shoreline in and around Lake Shelbyville or cruising through the country to visit Amish establishments and explore a simpler way of life. Youre invited to visit, become a resident or open a business. We welcome you to our home.
