STEM Student Density & Talent Inflows Propel Ann Arbor to Top of Midwest Innovation Rankings

Naperville, Ill., leads in STEM business density, with 10.3% of its companies classified in science and engineering sectors. That is the highest share among the region’s top 20 cities, surpassing even much larger metros like Chicago, which ranks fifth on this metric. Altogether, Naperville is home to roughly 600 STEM-focused firms.

Traditionally anchored by corporate campuses along the I-88 corridor, Naperville’s innovation economy has diversified in recent years. The city has seen expansion across advanced manufacturing, life sciences and digital infrastructure. Incubator hub88 (now part of Chicago’s 1871 network) continues to support early-stage companies, while nearby Fermilab remains a global center for particle physics and emerging quantum computing research.

Ann Arbor, Mich., ranks second, with 8.4% of local businesses in STEM fields. Its tech ecosystem now spans cybersecurity, biotech (ONL Therapeutics and Genomenon) and robotics (Refraction AI). Homegrown startups are also scaling: May Mobility, an autonomous vehicle firm with more than 260 employees, has raised $387 million in funding and continues to hire locally.

Madison, Wis., follows with a 6% STEM share and about 500 science and engineering businesses citywide. University Research Park anchors around 100 of these firms, but major employers like biotech giant Promega, founded in 1978, have created today’s robust ecosystem. At the startup level, StartingBlock hosts more than 100 startups and has become a central node for Madison’s entrepreneurial scene.

To the west, Minneapolis came in fourth in density at 5.2%. Even so, it had the second-highest absolute number of STEM businesses among the Midwest cities studied, 1,727 in total, behind only Chicago’s raw total (2,879 for a 5% share of all companies in the Windy City).

As with the STEM-density metric, two cities stand out from the rest. None of the top 20 Midwestern cities saw growth in STEM establishments above 10% between 2018 and 2022, though that may be partly because renewed momentum in STEM sectors postdates our analysis window.

Columbia, Mo., led the list with a 9.2% increase in STEM businesses during the period. The city’s total rose from 119 to 130 firms, not a large base but a meaningful uptick given Columbia’s smaller size. Statewide, more than $50 million in early-stage funding helped fuel activity across biotech, edtech, fintech and AR/VR. In Columbia itself, companies like Nex4 highlight the city’s growing tech mix.

Grand Rapids, Mich., ranked second, posting a 7.7% increase that added around 30 tech-related businesses to the local economy. Standout firms that launched or expanded during that period include BAMF Health, CertifID, Claira, The Patient Co. and WedgeHR. Last year, growing ticketing platform Ludus chose Grand Rapids for its new headquarters, beating out larger markets like Austin, Texas, and Chicago.

From there, the numbers drop off. Cities like Columbus, Ohio (4%), in third place, added around 30 STEM firms. That said, 11 of the 20 cities on our list saw a net decline in STEM business counts during the five-year period. Many of those same cities posted strong gains in STEM employment, suggesting that while company formation may have slowed, hiring still grew.

Madison, Wis., tops the Midwest for life sciences and R&D space, with roughly 2.3 million square feet either completed or under construction as of March 2025. The city’s research footprint has grown steadily in recent years, anchored by the University of Wisconsin-Madison and a maturing biohealth sector. In 2019, Exact Sciences helped set the pace with a 169,000-square-foot clinical lab, followed by Element Labs’ 151,000-square-foot startup facility at University Research Park, which opened in 2024. Fujifilm Cellular Dynamics is now building a new, 138,000-square-foot headquarters across town, aiming to double its local workforce by the end of the decade.

Further west, most of St. Paul, Minn.’s 2.2 million square feet is tied to long-standing institutional players. Boston Scientific’s Arden Hills campus accounts for more than half of the total at 1.14 million square feet, where the company developed its Watchman heart device. 3M’s Building 280, opened in 2015, adds another 460,000 square feet and houses around 700 researchers across disciplines.

Chicago comes in third at 1.7 million square feet, although its recent activity has outpaced the rest of the region. Since 2020, the city has added more than 1 million square feet across three new facilities, including two Fulton Labs buildings in West Fulton and a life sciences project at 1229 W. Concord in Lincoln Yards. On the South Side, Hyde Park Labs is under construction at 5217 S. Harper Ave., adding 300,000 square feet to the University of Chicago’s innovation footprint. It is anticipated to deliver by mid-2025.

St. Louis sits just behind, with 1.5 million square feet of life sciences and R&D space. The standout is the 609,000-square-foot Jeffrey T. Fort Neuroscience Research Building, completed in 2023 by Washington University School of Medicine. Located in the Cortex Innovation District, it is one of the largest life sciences facilities completed in the Midwest in recent years.

Kansas City, Mo., rounds out the top five at 1.49 million square feet. The largest single contributor remains Oracle’s 805,000-square-foot R&D campus, delivered in 2017.

Chicago took the lead in Midwest patent production, logging 45,488 patents granted between 2020 and 2024. The city’s scale in this category is no surprise. A deep network of research universities, Fortune 500 R&D centers and intellectual property infrastructure has long made it the region’s anchor for innovation output.

More notable, perhaps, is who comes next: Cincinnati ranked second with 31,181 patents granted, well ahead of larger peers like Minneapolis and Indianapolis. The University of Cincinnati has played a central role, nearly doubling its patent output in recent years. Expanded research funding, a revamped tech transfer office and deeper corporate ties (particularly with Procter & Gamble, Microsoft and Kroger) have sharpened the city’s ability to turn academic research into market-ready technologies. Many of those partnerships are housed at the university’s 1819 Innovation Hub, now a core piece of Cincinnati’s innovation infrastructure.

According to the most recently available data from the National Center for Education Statistics (NCES), for every 100,000 residents in St. Louis, there are 3.2 four-year institutions offering degrees in engineering, life sciences, mathematics or physics. Springfield, Mo., follows with 2.9, finishing ahead of St. Paul, Minn., and Columbia, Mo., and putting Missouri in three of the top four spots.

We also looked at vocational providers offering STEM-aligned programs, a category that includes health care, IT, advanced manufacturing and skilled trades. Because vocational programs often serve adult learners, we used per-resident (not per-student) figures to show where the deepest technical pipelines are.

Springfield, Ill., ranked first with 1.8 such institutions per 100,000 residents. Cincinnati came in second, adding to its strong showing across education metrics.

These programs have become an increasingly important on-ramp into the tech workforce, especially as students weigh faster, lower-cost alternatives to four-year degrees. In places like Springfield, Ill., and Cincinnati, it isn’t just about headcount. It’s coordination.

Springfield’s Lincoln Land Community College runs short-term training programs backed by state workforce grants and maintains close ties with public-sector employers. In Cincinnati, co-op programs, union apprenticeships and tech transfer pipelines all plug into a broader system that starts in high school and extends through adult reentry and upskilling.

The Midwest’s strongest talent pipelines often start in the classroom, and in a few cities, STEM students make up a striking share of the college population. Nowhere is that more true than in Ann Arbor, Mich., where 229 out of every 1,000 students are enrolled in science or engineering programs. The University of Michigan drives much of that. Its computer science and engineering departments rank among the best in the country, and in 2023 alone, the school awarded more than 1,200 degrees in computing fields. That scale of output, paired with a high graduate retention rate, helps sustain a steady stream of talent for local and national employers.

Fargo, N.D., isn’t far behind at 217 STEM students per 1,000 enrolled. Here again, North Dakota State’s programs are deeply tied to the region’s economy, from biosystems and ag tech to computer science. A 2022 NSF grant of $1.4 million helped expand student research in the life sciences, and demand from firms like Microsoft’s Fargo campus has kept enrollment strong. The result is a homegrown workforce aligned with the region’s tech and applied science sectors, one that has grown fast in recent years.

In Madison, Wis., 184 out of every 1,000 college students are pursuing STEM degrees. The University of Wisconsin-Madison has seen continued interest in computer science, now one of its most selective majors. Research in engineering and biosciences remains a core strength, backed by a $1.3 billion research budget and a long track record of public-private collaboration. Local firms like Epic Systems and Exact Sciences offer hands-on internships, while the university continues to enroll large numbers of in-state students, with 3,813 in the 2023 freshman class.

Ann Arbor, Mich., leads the region with a 92% graduation rate for four-year programs, followed by Madison, Wis. (88%), Columbus, Ohio (85.2%), and Minneapolis (80%). At the other end, cities like Springfield (both Illinois and Missouri), Dayton, Ohio, and Naperville, Ill., average closer to 50% to 53%.

Part of that gap comes down to structure. Flagship schools like Michigan (with its $17 billion endowment), Wisconsin and Ohio State are selective, well-funded and built around full-time residential life. They admit students who are more likely to finish, and then give them the support to do it.

Other cities don’t always have that same setup. Wright State in Dayton, Ohio, has a six-year graduation rate of around 44%. Many students commute, attend part-time or balance school with work. Advising is also thinner and funding is tighter. Although the University of Dayton posts stronger outcomes, it draws a smaller, more traditional pool and doesn’t move the city average by much.

After looking at how many vocational institutions operate in each city, this next measure shifts the focus to what they offer: how many of those programs are STEM-focused relative to the local population.

Dayton, Ohio, was well ahead of all cities with 87 STEM vocational programs per 100,000 residents, almost double Madison, Wis. In Dayton, Wright-Patterson Air Force Base and the city’s legacy in aerospace and manufacturing have shaped steady demand for hands-on skills. Community colleges and career tech centers work directly with employers to offer programs in areas like engineering technology, avionics and cybersecurity. At the same time, the city’s older workforce and lower bachelor’s-degree attainment help sustain demand for short, job-focused training that offers a clear path into the workforce.

Next is Ann Arbor, Mich., with 54 STEM vocational programs per 100,000 residents. Washtenaw Community College (Michigan’s largest transfer school to the University of Michigan) anchors much of that system. It offers more than 60 programs across advanced manufacturing, IT, cybersecurity, health care and mobility, with around 1,000 students enrolled in STEM-focused tracks at any given time.

Recent state grants totaling nearly $2 million will help WCC expand into semiconductors and battery tech, aligning with Michigan’s broader push into EV and clean-energy industries. Public funding keeps tuition low, while partnerships with local employers support internships, apprenticeships and direct placement. Bridging programs like STEM Scholars and M-STEM Academies further link two- and four-year outcomes.

Indianapolis awarded more vocational STEM degrees and certificates than any other Midwestern city in 2023, roughly 5,700 in total, according to NCES data.

That puts it well ahead of cities like Naperville, Ill. (2,024), Madison, Wis. (1,298), and Dayton, Ohio (1,111), and notably above Chicago, which ranked 10th despite its size.
