A developed country (also known as an industrialised country or more economically developed country (MEDC)) is a country that has more businesses and infrastructures (roads, airports, electricity, etc) than a developing country. The numbers most used for measuring economic growth is gross domestic product (GDP) and per capita income (average money per person).
