Statistical Measures of Unemployment

Statistical Measures of Unemployment Most data regarding unemployment in the United States is collected and reported by the Bureau of Labor Statistics. The BLS divides unemployment into six categories (known as U1 through U6), but these categories dont line up directly with the way that economists categorize unemployment. U1 through U6 are defined as follows: U1 Percentage of labor force unemployed 15 weeks or longerU2 Percentage of labor force who lost jobs or completed temporary workU3 Percentage of labor force who are without jobs and have looked for work in the last four weeks (note that this is the officially reported unemployment rate)U4 U3 plus the percent of the labor force that counts as discouraged workers, i.e. people who would like to work but have stopped looking because they are convinced that they cant find jobsU5 U4 plus the percent of the labor force that count as marginally attached or loosely attached workers, i.e. people who would theoretically like to work but havent looked for work within the past four weeksU6 U5 plus the percent of the labor force that counts as underemployed, i.e. part-time workers who would like to work more but cant find full-time jobs Technically speaking, the statistics for U4 through U6 are calculated by adding discouraged workers and marginally attached workers into the labor force as appropriate. (Underemployed workers are always counted in the labor force.) In addition, the BLS defines discouraged workers as a subset of marginally attached workers but is careful not to double count them in the statistics. You can see the definitions directly from the BLS. While U3 is the main officially reported figure, looking at all of the measures together can provide a broader and more nuanced view of what is happening in the labor market.
