In 2015 according to the results of the regional development composite index five out of the 25 Portuguese NUTS 3 level regions stood above the national average in terms of the overall regional development – the metropolitan areas of Lisboa and Porto, Alto Minho, Região de Aveiro and Região de Leiria.
The territorial image of the competitiveness index shows that regions with more favourable performances are concentrated in the Portuguese mainland coast. The metropolitan area of Lisboa was the leader in the competitiveness index. The Região de Aveiro, the metropolitan area of Porto and, marginally Alentejo Litoral also stood above the national average.
As for cohesion, the results illustrate a more balanced country than the one resulting from the competitiveness index, since in nine out of the 25 level 3 NUTS regions the cohesion index stood above the national average. In this dimension of regional development, the 2015 results suggested a more cohesive territory in the mainland centre sub-regions and in the northern coastal regions, especially in the metropolitan area of Lisboa and Região de Coimbra.
Regarding the environmental quality index, the 2015 results highlight the inner mainland and the two autonomous regions. The national average was exceeded in 12 out of the 25 NUTS 3 regions and the territorial disparity was weaker than the one observed for the other components. In 2015, Alto Alentejo was the leader in the environmental quality index.
