Something significant is happening in Social Security – people are retiring and taking their benefits later. In 1997, 57% of men claiming their retirement benefits under Social Security were 62, the earliest age at which one can do so. By 2017, that share had dropped to 34% because more people elected to put off claiming their benefits. I’m not sure why the study only involves men since women are also eligible for social security benefits, but I suspect the reasons to delay benefits apply universally.
