Full edition for scientific use. In addition to the core variables of the Microcensus Labour Force Survey (LFS), the LFS also has so-called ad-hoc-modules (AHM) that can vary from year to year. The EU-LFS ad-hoc-module 2017 on ‘Self-employment’ is divided into three submodules: economically dependent self-employment, working conditions for self-employed people, the self-employed and employees. All employed persons of a household were interviewed. The questions of the ad-hoc-module were asked following the questions of the basic programme. The dataset also includes all questions of the main survey of the Microcensus 2017.
