This paper analyzes convergence of unemployment rates in Poland at the local level by testing nonlinear convergence, applying the modified KSS-CHLL test for each pair of territorial units. The results suggest that actually the convergence is a rare phenomenon and occurs only in 3 227 cases out of potential over 70 000 combinations. This paper inquires which systematic reasons contribute to this phenomenon.
