Aware of its analytical importance this paper adopts such method of study to identify groups of Portuguese administrative regions that share similar patterns regarding the characteristics of unemployed registered individuals. The regional distribution of the unemployed individual characteristics is of core importance for the development of public policies directed to fight the unemployment phenomenon, especially in times of crisis. Preliminary results show a clear division of the territory into four regions – north and south and urban and rural areas - that stresses the importance of designing well-directed public labour policies.engPortugalK-means cluster analysisUnemploymentNUTII regionsjournal article
