RCLCO's Economic Hot Spot map, first published in 2013 to gauge growth in the U.S. following the Great Financial Crisis, shows Indy jumping from 21st to fouth in one year.
From the report:
"Indianapolis is a prime example of a Midwest market that performs exceptionally well in the new rankings—increasing from 21st to fourth. Overall, Indianapolis has a growing job base in industries that are integral to the nation’s economy. It is a major healthcare hub, including several large hospital systems as well as the Indiana University Medical Center, the second-largest medical school in the nation, with a research and teaching faculty of more than 1,100 people. Additionally, the area is attracting tech companies, drawn to the educated work force and low costs. One example is Appirio, a cloud services firm, which moved its headquarters from San Francisco to Indianapolis in 2015, beating out other locations such as London and Tokyo. Why? The firm particularly cited an abundance of nearby universities from which it could hire."
