Forty-nine countries are currently designated by the United Nations as least developed countries (LDCs). The current criteria are: low national income (per capita GDP under $900 for countries now joining the list), weak human assets (a composite index based on health, nutrition and education indicators) and high economic vulnerability (a composite index based on indicators of instability of agricultural production and exports, inadequate diversification and economic smallness). Different thresholds are used for addition to, and graduation from, the list of LDCs. A country qualifies for addition to the list if it meets inclusion thresholds on all three criteria, and if its population does not exceed 75 million.
