Montana if you haven’t noticed is turning gray. Some 221,000 Montanans now identify as “retired,” about 25 percent of this state’s population above age 16, rising from 20 percent 30 years ago. Montana’s retirees, in fact, now outnumber children and teenagers in the state, who make up 20 percent of the population. Married couples in Montana, at the same time, are having fewer children, due in part to economic struggles and uncertainty.
