This site has a lot of good facts and graphs.
Eg., a more reality-based measure of unemployment (U-6), than the official one (U-3), shows the unemployment rate at 12.5%.
So what does U-6 include that U-3 doesn’t?
(a) Marginally attached workers who currently are neither working nor looking for work but indicate that they want and are available for a job and have looked for work sometime in the past.
(b) Persons employed part-time for economic reasons but want full-time work.
(c) Discouraged works who are a subset of marginally attached. These folks have essentially given up looking for work because of the job market.
