I thought the "jobless rate" included discouraged workers and
involuntary part-timers?  Does this mean that those using that term
chose one that the BLS uses as a synonym for the unemployment rate and
the BLS uses a term as a synonym that they are aware us being used as an
alternative indicator.  I have seen what I defined as the jobless rate
also called the "marginalization rate" I believe (by Boston, R.
Williams).
