The Least Developed Countries (LDC) is a list of the countries that, according to the United Nations, exhibit the lowest indicators of socioeconomic development, with the lowest Human Development Index ratings of all countries in the world. The concept of LDCs originated in the late 1960s and the first group of LDCs was listed by the UN in its resolution 2768 (XXVI) of 18 November 1971. A country is classified among the Least Developed Countries if it meets three criteria:
LDC criteria are reviewed every three years by the Committee for Development Policy (CDP) of the UN Economic and Social Council (ECOSOC). Countries may "graduate" out of the LDC classification when indicators exceed these criteria. The United Nations Office of the High Representative for the Least Developed Countries, Landlocked Developing Countries and Small Island Developing States (UN-OHRLLS) coordinates UN support and provides advocacy services for Least Developed Countries. The classification (as of 24 January 2014[update]) applies to 48 countries.
Since the LDC category was initiated, only four countries have graduated to developing country status. The first country to graduate from LDC status was Botswana in 1994. The second country was Cape Verde in 2007.Maldives graduated to developing country status on 1 January 2011, while Samoa graduated in 2014. It is anticipated that Equatorial Guinea and Vanuatu will be the next countries to be promoted from LDC status, followed by Angola. At the UN's fourth conference on LDCs held in May 2011, delegates endorsed a goal targeting the promotion of at least half the current LDC countries within the next ten years.
