Developing country is a term generally used to describe a nation with a low level of material well being. There is no single internationally-recognized definition of developed country, and the levels of development may vary widely within so-called developing countries, with some developing countries having high average standards of living.
Some international organizations like the World Bank use strictly numerical classifications. The World Bank considers all low- and middle- income countries as "developing". In its most recent classification, economies are divided using 2008 Gross National Income per capita. In 2008, countries with GNI per capita below US$11,905 are considered developing. Other institutions use less specific definitions.
Countries with more advanced economies than other developing nations, but which have not yet fully demonstrated the signs of a developed country, are grouped under the term newly industrialized countries.
