Confused About The Jobs Report?  Ezra Klein, In The Washington Post, Shows You The Really Important Number, U 6.  See For Yourself Below.

U6 is not an unemployment measure. It includes part-time workers who want full-time work. So it doesn’t count the increase in part-time work. But every measure of actual unemployment — U1, U2, U3, U4, and U5 — went down. You can see them all here. Again, there’s no mystery.
