Generally, developed countries have more post-industrial economies, meaning that the service sector provides more resources than the industrial sector. These are not similar to developing countries, which are in the process of pre-industrialization or industrialization and are almost entirely agricultural, some of which may fall into the least developed countries category. At present time, Burundi is the poorest country in the world. Basically, there is no established conference on the designation of "developed" and "developing" countries or territories in the UN system. 

The Human Development Index is a scale that was created by the United Nations (UN) to measure human development in a country. HDI looks at a country's human development such as health, longevity, and education. HDI is set from 0 to 1 and most developed countries need to have scored more than .80. It can be used to determine the best countries to use because those who are generally advanced have a higher standard of living. Developing countries later became developed countries through their economic development.
