The publication was prepared on the basis of generalized results of the sample Labour Force Survey (LFS), conducted in the third quarter of 2017. The aim of the study was to assess the situation in terms of economic activity of the population, i.e. the fact of performing work, being unemployed or economically inactive in the reference week. The publication comprises the analytical and tabular parts as well as the explanation of basic definitions and concepts. The analytical commentary has been enriched with the graphic presentation of data in the form of graphs.
