(Radio Iowa) A new study shows the three state universities add nearly 15 billion dollars to the state economy. The study from the labor market analytics firm Lightcast shows the contributions form the University of Iowa, Iowa State University, and the University of Northern Iowa were equal to approximately seven-point-one percent of the total gross state product of the state. The study notes university activity supports nearly 200-thousand jobs in the state, which is one out of 10 jobs, and returns nearly three dollars for every taxpayer dollar spent. The study also outlines the impact of student education, alumni, and extension and outreach services. You can see more details of the report at RadioIowa.com
