86.9% of all statistics are made up....
I think what the OP may be referring to is the current definition of unemployed used in the stats. Say there are 100 people that live on a street. Of those 100 people, 92 have jobs, and 8 have just lost their jobs. Unemployment rate for that street is 8% (8/100). A year later, 2 of the 92 employed have lost their job and have been replaced by 2 of the 8 unemployed. The unemployment rate stays at 8%. Another year goes by with no change. 92 people still have jobs. 2 people have been unemployed for 1 year, and 6 people have been unemployed for 2 years. Those 6 people are now considered "out of the workforce". The unemployment rate magically drops to 2% (2/94).
