A developing country, also called a less-developed country, is a nation with a lower standard of living, underdeveloped industrial base, and low Human Development Index (HDI) relative to other countries. On the other hand, since the late 1990s developing countries tended to demonstrate higher growth rates than the developed ones. There is no universal, agreed-upon criterion for what makes a country developing versus developed and which countries fit these two categories, although there are general reference points such as a nation's GDP per capita compared to other nations. Also, the general term less-developed country should not be confused with the specific least developed country.There is criticism of the use of the term developing country. The term implies inferiority of a developing country or undeveloped country compared to a developed country, which many countries dislike. It assumes a desire to develop along the traditional Western model of economic development which a few countries, such as Cuba and Bhutan, choose not to follow. An alternative measurement that has been suggested is that of gross national happiness, measuring the actual satisfaction of people as opposed to how industrialised a country is.Countries with more advanced economies than other developing nations but that have not yet demonstrated signs of a developed country, are often categorized under the term newly industrialized countries.According to authors such as Walt Whitman Rostow, developing countries are in transition from traditional lifestyles towards the modern lifestyle which began in the Industrial Revolution in the 18th and 19th centuries.
