Michigan was the eleventh-oldest state in 2016, with a median age of 39.7 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-aged and older residents outpaces that of children and young adults. States with a high median age among residents may be good at attracting retirees, but this also can be a sign that younger people are seeking out other places to work and raise a family.
