How to calculate life expectancy & why it matters

Social Security: It’s Worse Than You Think

This Opinion piece in the Sunday Times is a summary of a Demography article where the authors argue that the Social Security Administration underestimates how long Americans live. That means the trust fund will run out two years earlier than the government has predicted.

Here’s the link to the original article in Demography:

This article has quite a few references to former PSC post-doc, John Wilmoth, who has also written on mortality projections and life expectancy.

Finally, for one more set of mortality estimates and methodology, see the Census Bureau’s National Population Projections web page. They have always projected higher life expectancy than the Social Security Administration, but their methodology is not the same as these authors:
