Money may not buy love, but it appears to buy years.
Economist Barry Bosworth at the Brookings Institution crunched the numbers and found that the richer you are, the longer you’ll live. And it’s a gap that is widening, particularly among women.
Mr. Bosworth parsed this data from the University of Michigan’s Health and Retirement Study, a survey that tracks the health and work-life of 26,000 Americans as they age and retire. It is especially valuable as it tracks the same individuals every two years in what’s known as a longitudinal study, to see how their lives unfold.
