Life expectancy in the United States has stalled for three straight years, the government announced Wednesday.
A child born last year can expect to make it to 78 years and 9 1/2 months — the same prediction made for the previous two years.
In most of the years since World War II, life expectancy in the U.S. has inched up —- thanks largely to medical advances, public health campaigns and better nutrition and education. The last time it was stuck for three years was in the mid-1980s.
What does this mean for the future solvency of Social Security? Beats the crap out of me. But it sure casts doubt on all those who preach “demography is destiny” and “we are all living longer so work until you are 70”.
On a more mathy note small changes in input into Social Security models can have amazing effects on output, particularly over 75 year actuarial projections. Tweak some mortality and immigration assumptions and results change dramatically. We don’t even have to go the MJ.ABW. Though More Jobs. At Better Wages would itself have some outsized effects.
