Development

A developed country is a country that manages to satisfy basic needs of its population (health, housing, education, etc ...). Today, we measure the development level of a country by placing a scale on which the HDI (Human Development Index). This index includes 3 criteria: longevity, knowledge and standard of living. We note that most countries with high HDI are located in the northern hemisphere, hence the expression "North - South". Two country groups stand out: * high HDI: Northern countries, rich countries, industrialized countries, developed countries. The population of these countries represents 20% of world population but consume 80% of global wealth. * Medium or low HDI; South, poor countries, countries of the third - world countries development.
