Doing some research, I think I see the answer...the Department of Labor simply "estimates" the percentages based on polling data. Then it feeds the info to the media. This is from the 'Bureau of Labor Statistics'....
"As mentioned previously, the labor force is made up of the employed and the unemployed. The remainder—those who have no job and are not looking for one—are counted as "not in the labor force." Many who are not in the labor force are going to school or are retired. Family responsibilities keep others out of the labor force.
A series of questions is asked each month of persons not in the labor force to obtain information about their desire for work, the reasons why they had not looked for work in the last 4 weeks, their prior job search, and their availability for work. These questions include:
Do you currently want a job, either full or part time?
What is the main reason you were not looking for work during the LAST 4 WEEKS?
Did you look for work at any time during the last 12 months?
LAST WEEK, could you have started a job if one had been offered?
These questions form the basis for estimating the number of persons....."
http://www.bls.gov/cps/cps_htgm.htm#nilfA poll! Have any of you, or your friends, ever been polled by the 'Bureau of Labor Statistics'?
I sure haven't.
And, of course, you can trust the Government, and their pollsters, to tell us 'the truth, the whole truth, and nothing but the truth".
