This article aims to propose the construction of a regional barometer of the sectoral economic situation. The study focuses on economic variables that represent specific sectors of voivodeship’s economy and their cyclical adjustment as component variables of the regional barometer of the sectoral economic situation. As a result of the research, variables with the properties of simultaneous and leading variables were distinguished to assess the state of the economic situation in individual sectors of the regional economy. The results indicated that fluctuations in economic activity in the regions are generally not consistent with changes in the economic situation of the country as a whole. Each region, being a separate administrative unit of the country and having a distinct economic structure, development level, and geographical location, has its own business cycle for each sector.
