The number of Americans designated as not in the labor force in February was 89,304,000, a record high, up from 89,008,000 in January, according to the Department of Labor. This means that the number of Americans not in the labor force increased 296,000 between January and February.
The Bureau of Labor Statistics (BLS) labels people who are unemployed and no longer looking for work as not in the labor force, including people who have retired on schedule, taken early retirement, or simply given up looking for work.
The increase marks the second month in a row, after rising in January from 88.8 million in December. Those not in the labor force had declined in December from 88.9 million in November.
