United Kingdom and Denmark outperforming Italy and France. However, large economic events like the Great Depression can lead to similar unemployment rates across the globe. In 2013, the ILO adopted a resolution to introduce new indicators to measure the unemployment rate. LU1: Unemployment rate: [persons in unemployment / labour force] × 100 LU2: Combined rate of time-related underemployment and unemployment: [(persons in time-related underemployment + persons in unemployment) / labour force] x 100 LU3: Combined rate of unemployment and potential labour force: [(persons in unemployment + potential labour force) / (extended labour force)] × 100 LU4: Composite measure of labour underutilization: [(persons in time-related underemployment + persons in unemployment + potential labour force) / (extended labour force)] × 100 European Union (Eurostat) Eurostat, the statistical office of the European Union, defines unemployed as those persons between age 15 and 74 who are not working, have looked for work in the last four weeks, and are ready to start work within two weeks; this definition conforms to ILO standards. Both the actual count and the unemployment rate are reported. Statistical data are available by member state for the European Union as a whole (EU28) as well as for the eurozone (EA19). 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.
