leastdeveloped

Least Developed refers to a designation used by the United Nations to identify the world's most impoverished and vulnerable economies. The term most commonly appears as Least Developed Countries (LDCs), a group created to target development assistance and policy attention toward nations facing multi‑dimensional poverty, weak human development, and high exposure to economic and environmental shocks. The classification is intended to guide international cooperation, trade preferences, and concessional finance in ways that support durable progress.

The UN uses three criteria to determine LDC status: income, human assets, and economic vulnerability. A country is evaluated for each criterion by an index that measures economic strength, health and education indicators, and exposure to structural risks and shocks. A country does not have a fixed number of indicators to meet in every case; thresholds are reviewed periodically by the UN Committee for Development Policy (CDP). Countries remain on the list so long as they do not meet graduation thresholds, and they can be removed only after a formal review showing sustained progress in at least two of the three criteria. Graduation decisions are made through the CDP and are followed by a transition period, typically three years, during which time previously available supports are gradually adjusted.

Benefits associated with LDC status include access to preferential trade terms, expanded official development assistance, and targeted capacity-building programs. However, graduation from the LDC category can raise concerns about funding and market access, so transition plans often accompany graduation to ease the shift toward ordinary financing and trade arrangements.

Examples of countries commonly cited as or historically classified among LDCs include Bangladesh, Ethiopia, Haiti, Mozambique, Nepal, Rwanda, Tanzania, and Uganda. The list is maintained and periodically revised by the United Nations, reflecting changes in development progress across the world.
