Least developed countries

The least developed countries (LDCs) are developing countries listed by the United Nations that exhibit the lowest indicators of socioeconomic development. 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) on 18 November 1971.

A country can be classified among the least developed countries when it meets the three following criteria:

As of December 2024, 44 countries were still classified as LDC, while eight graduated between 1994 and 2024. The World Trade Organization (WTO) recognizes the UN list and says that "Measures taken in the framework of the WTO can help LDCs increase their exports to other WTO members and attract investment. In many developing countries, pro-market reforms have encouraged faster growth, diversification of exports, and more effective participation in the multilateral trading system."

LDC criteria are reviewed every three years by the Committee for Development Policy (CDP) of the UN Economic and Social Council (ECOSOC). Countries may be removed from the LDC classification when indicators exceed these criteria in two consecutive triennial reviews. 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 December 2020^[update]) applies to 46 countries.

At the UN's fourth conference on LDCs, which was held in May 2011, delegates endorsed a goal targeting the promotion of at least half the current LDC countries within the next ten years. As of 2018, ten or more countries were expected to graduate in 2024, with Bangladesh and Djibouti already satisfying all criteria in 2018.

There is one country which presently meets the criteria and two countries which previously met the criteria for LDC status, but declined to be included in the index, questioning the validity or accuracy of the CDP's data: Ghana (no longer meets criteria as of 1994), Papua New Guinea (no longer meets criteria as of 2009), and Zimbabwe.

Least developed countries can be distinguished from developing countries, "less developed countries", "lesser developed countries", or other similar terms.

The term "less economically developed country" (LEDC) is also used today. However, in order to avoid confusion between "least developed country" and "less economically developed country" (which may both be abbreviated as LDC), and to avoid confusion with landlocked developing country (which can be abbreviated as LLDC), "developing country" is generally used in preference to "less-developed country".
