Missing: 5.4 Million Workers

Millions of Americans have vanished from the US labor force in the past three years, many of them so discouraged by long, fruitless job searches that they have given up looking for work, convinced that no employer wants them, according to a new study

The Center for Labor Market Studies at Northeastern University found that there were 5.4 million fewer people in the workforce last year than projected by the Labor Department in 2008 - many the “hidden unemployed’’ who, no longer searching for work, are not counted in the official jobless rate. In Massachusetts, their numbers have more than doubled over the past decade to about 120,000.
