Michigan was the ninth-oldest state in 2015, with median age increasing by 0.1 years from 2014 to 2015. Since 2006, the state’s median age has increased by 2.4 years. Michigan’s median age was higher than all of its peers and all of the “Top Ten” states except Pennsylvania.
What It Is: Median age of state residents.
Why It Matters: Increase in the median age is an indicator of an aging population, where the population growth rate of middle age and senior citizens outpaces that for children and young adults. States with a high median age among residents may be good at attracting retirees, but it also can be a sign that younger people are seeking out other places to work and raise a family.
