It's the percent of working age (25-54) adults in the labor force. The unemployment rate has lots of oddities that can make the economy seem better (or worse) than it often is. Note for example the long, slow, decline from 2008 to 2015, long after the recession was officially over -- and how we've currently erased almost all gains since that nadir.
Employment rate is better for seeing how many people are and aren't working.
Adults 25-54: https://fred.stlouisfed.org/series/LNS12300060
Was near an all-time high until last February mainly due to women joining the workforce, though with a sharp drop in the past year.
Males 25-54: https://fred.stlouisfed.org/series/LREM25MAUSA156S
Was down about 8 points from the peak in the 60s in 2019, then dropped another 5 points in 2020. Still slightly more likely to be employed than women in the same age range.
I would assume the probability of loss or reduction in income is significant for many people once they reach 50+.
It is not a pretty picture
55+ is at 38%
20+ is at 69%
18% of the pop is 65 and older
