DeKalb earned the nickname "Barb City" long before Northern Illinois University reshaped its identity, and today those two chapters coexist in a compact, walkable city about 65 miles west of Chicago. Founded in 1856, the city made its mark as the birthplace of commercial barbed wire, and that agricultural heritage still threads through local culture alongside the academic energy NIU brings to campus and downtown alike. Northern Illinois University, Northwestern Medicine Kishwaukee Hospital, and Meta's data center are major employment anchors, giving the city an economic foundation that extends well beyond its college-town reputation.
Life here spreads across several distinct pockets: the Downtown Lincoln Highway corridor draws those who want live performances at the 1929-era Egyptian Theatre and quick access to independent shops, while the Ellwood Historic District offers tree-lined streets and stately architecture. Neighborhoods near NIU stay close to campus events and public transit, and the eastern Sycamore Road corridor serves everyday errands with ease. Corn Fest, a free outdoor music gathering held each August, brings the whole community together in a way few other events can. Housing ranges from classic single-family conversions and garden-style apartment communities to newer complexes built to serve the university crowd, giving renters a broad range of options at accessible price points.
Dekalb brings that scenic American farmland charm to a modern living style in Northern Illinois.
Dekalb is proud to call it's self the home of Northern Illinois University.
Dekalb Illinois is Huskie Country.
Fall Food Truck Wednesday runs Aug 28–Oct 30 each week at NIU.

The GreatSchools Rating helps parents compare schools within a state based on a variety of school quality indicators and provides a helpful picture of how effectively each school serves all of its students. Ratings are on a scale of 1 (below average) to 10 (above average) and can include test scores, college readiness, academic progress, advanced courses, equity, discipline and attendance data. We also advise parents to visit schools, consider other information on school performance and programs, and consider family needs as part of the school selection process.
