\”Social Security eligibility begins at age 62, and approximately one third of Americans immediately claim at that age. We examine whether age 62 is associated with a discontinuous change in aggregate mortality, a key measure of population health. Using mortality data that covers the entire U.S. population and includes exact dates of birth and death, we document a robust two percent increase in male mortality immediately after age 62. The change in female mortality is smaller and imprecisely estimated. Additional analysis suggests that the increase in male mortality is connected to retirement from the labor force and associated lifestyle changes.\”
This is a technical research paper that will only be accessible to the initiate, but you can get a good flavor of the results from a couple of figures. A first figure shows the patterns of claiming Social Security. There are various rules about the age at which different kinds of benefits can be claimed. For example Social Security disability benefits can be claimed earlier, but access to what most people think of as the usual Social Security Benefits starts at 62. The figure shows the step-change or discontinuity in number of people retiring at 62, followed by a slower rise in claiming benefits and a smaller jump at age 65.
