Americans take great pride in their work ethic. However, some people and cities tend to work harder than others. In order to rank the hardest-working cities in America, Kempler Industries recently analyzed data from the U.S. Census Bureau from nearly 200 cities across the U.S. with a population of 150,000 or more. They then ranked each city from hardest working to least based on five key metrics, average commute, average workweek hours, percent of 16-64 workforce population, percent of senior workforce population and percent of unused vacation days. Each metric was graded on a 100-point scale. The full analysis can be seen in the graphic below.
