Utah’s recovery from the Great Recession in 2008 has been one of the strongest in the nation. Among a few different reasons behind the speedy recovery is that we have an economy that mirrors the nation in its mixture of industries. In fact, Utah’s economy has been consistently ranked as one of the nation’s most diverse. With manufacturing in the northern Wasatch front, a varied services sector in Salt Lake County, the tech hub in Provo-Orem, mining/oil and gas in the Eastern region, and leisure and hospitality in Summit County and in south-southeastern Utah, it is not hard to see the diversity in Utah’s economy. But how can one make a quantitative assessment about the extent to which a state’s economy is more diverse than another’s? One answer is the Hachman Index (see here for more).
