The percent of population employed in and throughout Michigan remained lower than the national average in 2010. While the percent of the population employed in the U.S. was about 59% in 2010 that number was about 20 percentage points lower in Detroit while the state was only about 4 percentage points lower. Detroit’s employment levels have been documented as much lower than those at the county, regional, state, and national level. The employment to population ratio was calculated by taking the number of people in the civilian labor force and dividing it by the civilian non-institutional population. The civilian labor force is made up of those 16 years old or older who are employed or searching for a job and are not in the military or institutionalized.
