Labour Force Survey"The Labour Force Survey (LFS), which began in 1973 as an annual survey, is a unique source of articulated information using international definitions of employment and unemployment and economic inactivity, together with a wide range of related topics such as occupation, training, hours of work and personal characteristics of household members aged 16 years and over. From March 1992, quarterly data were made available and the survey became known as the Quarterly Labour Force Survey (QLFS). As well as the main survey, several sub-sample and derived datasets are also produced, including longitudinal series and a Eurostat version of the dataset."
