Claim: Portugal is a nation-state that has technological and infrastructural advances.

A developed country , industrialized country , more developed country , or `` more economically developed country '' -LRB- MEDC -RRB- , is a sovereign state that has a highly developed economy and advanced technological infrastructure relative to other less industrialized nations . Most commonly , the criteria for evaluating the degree of economic development are gross domestic product -LRB- GDP -RRB- , gross national product -LRB- GNP -RRB- , the per capita income , level of industrialization , amount of widespread infrastructure and general standard of living . Which criteria are to be used and which countries can be classified as being developed are subjects of debate .   Developed countries have post-industrial economies , meaning the service sector provides more wealth than the industrial sector . They are contrasted with developing countries , which are in the process of industrialization , or undeveloped countries , which are pre-industrial and almost entirely agrarian . As of 2015 , advanced economies comprise 60.8 % of global GDP based on nominal values and 42.9 % of global GDP based on purchasing-power parity -LRB- PPP -RRB- according to the International Monetary Fund . In 2015 , the ten largest advanced economies by GDP in both nominal and PPP terms were Australia , Canada , France , Germany , Italy , Japan , South Korea , Spain , the United Kingdom , and the United States .
