The one thing the current unemployment numbers do not account for is people retiring. These numbers are large and will continue to be.
Now back to our regularly scheduled arm flailing.
There are dozens of factors that they don't account for. Not a single person just attaining workforce age is considered to be unemployed. People who have gone from being an engineer to flipping burgers are considered fully employed. People that have ceased collecting unemployment are not considered to be unemployed. Women that would have gone back to work when their kids left home are not considered to be unemployed. People who have gone on disability (in record numbers) are not counted as unemployed.
Meanwhile, people who were working a single full time job, but are now working two part time jobs are being counted as two employed workers.
That is not true. They are not considered in the job pool.
