Did you mean 65? Only teachers and a few other public union members regularly retire at 55 in the US, and even for them many choose to continue working to earn a fatter pension.
Except, of course, for the rare people disciplined enough to be frugal and invested a lot of every pay check, and became self made multi millionaires.

Until I realized it's likely due to COVID-19 deaths.
So it only includes people who are working or looking for work. This kind of distinction is the key to the OP.
So thankfully the dip is mostly not deaths, but for example
- a second earner in a household who lost a job in April but hasn't looked for new work since, due to child care commitments
- a cook who was furloughed but knows there are no new kitchen jobs going right now, but isn't yet willing to do something else, so isn't looking
- a person who lost a job one year out from retirement and is just retiring early
But I am curious about that drop.
Edit: It would be interesting to compare this to an up-to-date graph of US deaths (all kinds), if one exists.
No, this is intentional deception. The party out of power talks about "real" inflation rates and "real" unemployment rates, and the party in power touts the official numbers.
The best number to go by for unemployment has always been the prime age employment (not unemployment) rate, and all honest discussions of the current state of employment start with it.
