The Unemployment figures are based on a household survey.
Break-down of numbers (rounded to nearest thousand) based on November 2008
census estimates and the
November Current Population SurveyTotal US Resident Population: 305,548,000
But what we're interested in is people who can actually participate in the labor market, so we exclude everyone under 16, everyone in the military (because they can't freely leave), and those in institutions or prison (because they can't freely enter). This leaves us the
Adult civilian non-institutional population: 234,828,000
But now, not everyone wants to work. That number is 75,127,000
So, number of people who are either working or want to work is 159,701,000
Worked Full time: 117,582,000
Part time by choice or non job market factors: 19,892,000
Usually full time, but currently part time due to business conditions or slow work: 5,354,000
Want full time but could only find part time: 1,509,000
Part time for other economic reasons: 272,000
Total employed then is 144,609,000
Of the people who say they want a job, 3,130,000 did not look for work in the last year or are not able (for whatever reason) to start work immediately. They are not considered unemployed or marginally attached because they are in no way participants in the labor market.
Of the 1,947,000 people who are available to work now, and looked in the last year, but not the last 4 weeks (the marginally attached), 1,339,000 didn't look because of personal circumstances (either inability until now to work, or lazy, or waiting for a response from past attempts etc) and 608,000 didn't look because they didn't think they'd find anything they were qualified (discouraged workers). None of these are considered unemployed because they're not participating in the labor market. These groups of the marginally attached and its subset of discouraged workers are important to track, but because they're not actually part of the labor market it's misleading to consider them "unemployed" because their situation cannot change.
That leaves us with those who don't currently have a job, but have actively looked in the last four weeks. These are the officially Unemployed (regardless of whether they ever collected or tried to collect benefits).
694,000 people are now looking for their first job.
2,659,000 had previously worked, were not looking for a job, but have just started.
1,060,000 people don't have a job because their last job was temporary in nature.
916,000 people quit.
1,166,000 are on temporary lay-off (this group doesn't have to be actively looking).
3,520,000 were fired or permanantly laid off.
Total Unemployed:10,015,000
