Michigan was the 10th oldest state in 2014. Michigan’s median age held steady from 2013 to 2014. This ended a trend that had seen the Michigan median age increase by 2.7 years since 2005. Michigan's median age was higher than all of its peers and all of the "Top Ten" states except for 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 of 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.
