Study by Maestas, Mullen and Powell (RAND) on population aging and economic growth cited in NYT
"This Economy Is Not Aging Gracefully" - New York Times. 6/15/2019.
"Consider the bluntest measure of progress: economic growth. Comparing growth across American states that are aging at different speeds, researchers from Harvard's Medical School and the RAND Corporation concluded that a 10 percent increase in the share of the population over 60 reduced the growth rate of per capita gross domestic product by 5.5 percent. They projected that aging would shave no less than 1.2 percentage points off annual economic growth this decade."
