Eurostat also includes a long-term unemployment rate, which is defined as part of the unemployed who have been unemployed for more than one year.The main source used is the European Union Labour Force Survey (EU-LFS). It collects data on all member states each quarter. For monthly calculations, national surveys or national registers from employment offices are used in conjunction with quarterly EU-LFS data. The exact calculation for individual countries, resulting in harmonized monthly data, depends on the availability of the data. United States Bureau of Labor statistics
The Bureau of Labor Statistics measures employment and unemployment (of those over 17 years of age) by using two different labor force surveys conducted by the United States Census Bureau (within the United States Department of Commerce) and/or the Bureau of Labor Statistics (within the United States Department of Labor) that gather employment statistics monthly. The Current Population Survey (CPS), or "Household Survey," conducts a survey based on a sample of 60,000 households. The survey measures the unemployment rate based on the ILO definition.The Current Employment Statistics survey (CES), or "Payroll Survey," conducts a survey based on a sample of 160,000 businesses and government agencies, which represent 400,000 individual employers. Since the survey measures only civilian nonagricultural employment, it does not calculate an unemployment rate, and it differs from the ILO unemployment rate definition. Both sources have different classification criteria and usually produce differing results.
In 2013, Representative Hunter proposed that the Bureau of Labor Statistics use the U5 rate instead of the current U3 rate.Statistics for the US economy as a whole hide variations among groups. For example, in January 2008, the US unemployment rates were 4.4% for adult men, 4.2% for adult women, 4.4% for Caucasians, 6.3% for Hispanics or Latinos (all races), 9.2% for African Americans, 3.2% for Asian Americans, and 18.0% for teenagers. Also, the US unemployment rate would be at least 2% higher if prisoners and jail inmates were counted.The unemployment rate is included in a number of major economic indices including the US Conference Boards Index of Leading Indicators a macroeconomic measure of the state of the economy.
