The paper looks at the issue of minimum wage in Poland and other EU member states. First, the definitions, measurement, dynamics and legislation related to the minimum wage are introduced. In the next section the authors discuss whether it is reasonable to regionally diversify the minimum wage in Poland, as the analysis shows that such economic indicators as the average wage, labour productivity and costs of living vary depending on the region. Authors claim that these factors speak in favor of regional diversification of the minimum wage.
