The RSM US Middle Market Business Index provides a leading measure on the performance of businesses that make up the heart and soul of our country's economy. In partnership with RSM, we've collected data on middle market firms since 2015 through quarterly surveys conducted by The Harris Poll. The survey is conducted four times a year, in the first month of each quarter: January, April, July and October.
The survey panel consists of approximately 1,500 middle market executives and is designed to accurately reflect conditions in the middle market.
