The aim of this paper was describe the determinants of the unemployment rates in the counties of Podkarpackie voivodeship between 2003 and 2008. The registered unemployment rates were presented, together with the rates of employed in tree sectors of the regional economy: agriculture, industry and services. The author also aimed to conduct statistical analysis of the influence of diversity of employed in different sectors on the unemployment rate in counties of Podkarpackie voivodeship. The highest unemployment rates were observed in counties, where agriculture plays the major role. Contrary to this, counties located near local biggest cities like Rzeszów and Krosno and traditionally the most developed local centers like Dębica, Mielec and Tarnobrzeg were characterized by relatively low unemployment rate because these counties are industry oriented.
