U.S. Employment Data December. A closer look at data, labor situation still Bleak.

The  number of unemployed persons in December was 10.4 millions.
 Among the unemployed, the number of job losers and persons who completed 
temporary jobs decreased by 365,000 in December to 5.4 million.
The number of long-term unemployed(those jobless for 27 weeks or more) was 3.9 million these 
individuals accounted for 37.7 % of the unemployed.

The number of persons employed part time for economic reasons (sometimes 
referred to as involuntary part-time workers) was essentially unchanged at 
7.8 million in December. These individuals were working part time because 
their hours had been cut back or because they were unable to find full-
time work. 

In December, 2.4 million persons were marginally attached to the labor force, 
little changed from a year earlier. (The data are not seasonally adjusted.) 
These individuals were not in the labor force, wanted and were available for 
work, and had looked for a job sometime in the prior 12 months. They were not 
counted as unemployed because they had not searched for work in the 4 weeks 
preceding the survey.

So if we take in account all these different definitions of employed persons that the U.S.

Bureau of Labor Statistics uses the Employment situation of the U.S. has improved but it still remains bleak
