Eurostat produces harmonised unemployment rates for individual EU Member States, the euro area and the EU. These unemployment rates are based on the definition recommended by the International Labour Organisation (ILO). The measurement is based on a harmonised source, the European Union Labour Force Survey (LFS). Based on the ILO definition, Eurostat defines unemployed persons as persons aged 15 to 74 who: are without work; are available to start work within the next two weeks; and have actively sought employment at some time during the previous four weeks.
