In Poland, two sources of data concerning unemployment rate are applied. The first one is closely linked to the registration of unemployed persons in the powiat labour offices and is called 'registered unemployment'. The second source is the data collected from the Labour Force Survey (Badanie Aktywnosci Ekonomicznej Ludnosci - BAEL), on the basis of which the labour force size and structure as well as the unemployment rate are assessed. When compared, the value of registered unemployment rate and the value of unemployment rate calculated on the basis of BAEL display some differences. The aim of this paper is to clarify the disparities between the registered unemployment rate and the unemployment rate estimated on the basis of BAEL, as well as to determine the factors leading to the differences in the process of calculating both indicators.
