The local economy is a controversial topic among Munsonians. While many older unemployed or underemployed residents strongly identify with the manufacturing identity of the city, newer residents identify with the city's shift towards educational and health services. Contention is greatest among residents living in the once-industrialized sections of the city's south side, as much of the economic growth over that last few decades has taken place on Muncie's north side. The city also struggles to retain college graduates. Despite Ball State's presence, only 32.2 percent of Delaware County's working-age adults (ages 25–64) hold a two-year or four-year college degree, which is below the national average.
