Least developed countries
View on Wikipedia
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.[1]
A country can be classified among the least developed countries when it meets the three following criteria:[2][3]
- Poverty – adjustable criterion based on the gross national income (GNI) per capita averaged over three years. As of 2018[update], a country must have GNI per capita less than US$1,025 to be included on the list, and over $1,230 to graduate from it.
- Human resource weakness (based on indicators of nutrition, health, education and adult literacy).
- Economic vulnerability (based on instability of agricultural production, instability of exports of goods and services, economic importance of non-traditional activities, merchandise export concentration, handicap of economic smallness, and the percentage of population displaced by natural disasters).
As of December 2024, 44 countries were still classified as LDC, while eight graduated between 1994 and 2024.[4] 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."[5]
Overview
[edit]

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.[6] 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.[4]
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.[7] As of 2018, ten or more countries were expected to graduate in 2024, with Bangladesh and Djibouti already satisfying all criteria in 2018.[8]
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.[9]
Usage and abbreviations
[edit]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".
During a United Nations review in 2018, the UN defined LDCs as countries meeting three criteria, one of which was a three-year average estimate of gross national income (GNI) per capita of less than US$1,025.[10]
UN conferences
[edit]
There have been five United Nations conferences on LDCs, held every ten years. The first two were in Paris, in 1981 and 1991; the third was in Brussels in 2001.
The Fourth UN Conference on Least Developed Countries (LDC-IV) was held in Istanbul, Turkey, on 9–13 May 2011. It was attended by Ban Ki-moon, the head of the UN, and close to 50 prime ministers and heads of state. The conference endorsed the goal of raising half the existing Least developed countries out of the LDC category in 2022. As with the Seoul Development Consensus drawn up in 2010, there was a strong emphasis on boosting productive capability and physical infrastructure, with several NGOs not pleased with the emphasis placed on the private sector.[7][11]
The Fifth UN Conference on Least Developed Countries (LDC-V) was split in two parts almost a year apart, between UN Headquarters in New York on 17 March 2022 and Doha on 5–9 March 2023.[12]
Trade
[edit]Issues surrounding global trade regulations and LDCs have gained a lot of media and policy attention thanks to the recently collapsed Doha Round of World Trade Organization (WTO) negotiations being termed a development round. During the WTO's Hong Kong Ministerial, it was agreed that LDCs could see 100 percent duty-free, quota-free access to U.S. markets if the round were completed. But analysis of the deal by NGOs found that the text of the proposed LDC deal had substantial loopholes that might make the offer less than the full 100 percent access, and could even erase some current duty-free access of LDCs to rich country markets.[13][14] Dissatisfaction with these loopholes led some economists to call for a reworking of the Hong Kong deal.[citation needed]
Chiedu Osakwe, as of 2001 the Director, Technical Cooperation Division at the Secretariat of the WTO, and adviser to the Director-General on developing country matters, was appointed as the WTO Special Coordinator for the Least Developed Countries beginning in 1999.[15] He worked closely with the five other agencies that together with the WTO constitute the Integrated Framework of action for the Least Developed Countries. They addressed issues of market access, special and differential treatment provisions for developing countries, participation of developing countries in the multilateral trading system, and development questions, especially the interests of developing countries in competition policy.[16] At the 28th G8 summit in Kananaskis, Alberta, Canadian Prime Minister Jean Chrétien proposed and carried the Market Access Initiative, so that the then 48 LDCs could profit from "trade-not-aid".[17] Additionally, the United Nations Sustainable Development Goal 14 advocates for an effective special and differential treatment of LDCs as integral parts of WTO fisheries subsidies negotiation.[18]
Market access preferences
[edit]Several countries grant preferential access to least developed countries. For instance, the European Union has implemented the Everything but Arms scheme, while Switzerland offers free access to its market for all products to LDCs.[19] Access to the Japanese market is also free for LDCs.[20]
Effective 1 December 2024, China eliminated tariffs for goods imported from all of the countries that the United Nations categorizes as least developed and with which China has diplomatic relations. Thirty-three of the countries benefiting from the agreement are in Africa and the non-African countries receiving zero tariff treatment are Yemen, Kiribati, the Solomon Islands, Afghanistan, Bangladesh, Cambodia, Laos, Myanmar, Nepal, and East Timor.[21]
List of countries

Delisted countries (graduated countries)
[edit]The three criteria (human assets, economic vulnerability and gross national income per capita) are assessed by the Committee for Development Policy every three years. Countries must meet two of the three criteria at two consecutive triennial reviews to be considered for graduation. The Committee for Development Policy sends its recommendations for endorsement to the Economic and Social Council (ECOSOC).[27]
After the initiation of the LDC category, eight countries 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.[28] Maldives graduated to developing country status at the beginning of 2011, Samoa in 2014,[6][29] Equatorial Guinea in 2017,[30] Vanuatu in December 2020,[31] Bhutan in December 2023,[32] and São Tomé and Príncipe in December 2024.[33]
The following countries are no longer categorized in the "least developed countries" group:
Sikkim (became a state within the Republic of India in 1975)[34][35]
Botswana (graduated from LDC status in December 1994)[36]
Cape Verde (graduated in December 2007)[36]
Maldives (graduated in January 2011)[36]
Samoa (graduated in January 2014)[37]
Equatorial Guinea (graduated in June 2017)[38]
Vanuatu (graduated in December 2020)[31]
Bhutan (graduated in December 2023)[32][39]
São Tomé and Príncipe (graduated in December 2024)[33]
Countries expected to graduate soon
[edit]- Bangladesh met the criteria twice, once in 2018 and again in 2021. The country will officially graduate from LDC status in November 2026, two years after it was supposed to, due to the COVID-19 pandemic.[40]
- Laos and Nepal will also graduate in November 2026.[41] The latter was originally selected to graduate to developing country status in 2018. However, the authorities of Nepal requested to postpone graduation until 2021.[42] Graduation was later pushed back an additional five years.
- Solomon Islands will graduate in December 2027.[43]
- Cambodia is expected to graduate in December 2029. It met the criteria in 2021 and was originally expected to graduate in 2027, but this was later postponed to ensure a smooth transition.[44]
- Senegal will graduate in December 2029.[45]
- Djibouti, Kiribati and Tuvalu could graduate from LDC status in 2027 at the earliest.[43]
- Comoros and Myanmar met the graduation criteria at least twice. They could be recommended for graduation in 2027.[43]
- Rwanda, Uganda and Tanzania met the graduation criteria for the first time in 2024. They could be recommended for graduation in 2027.[46][47][48]
- Angola was expected to graduate in 2021, but the preparatory period was extended by three years because of the economic difficulties of the country and its dependence on commodities.[49] Graduation was further postponed in December 2023, without any specific timeline.[50]
- Zambia and Timor-Leste met the graduation criteria in the past but no longer meet the qualification.[43]

Establishment of the Category
The category of least developed countries (LDCs) was established by the United Nations General Assembly through Resolution 2768 (XXVI), adopted on 18 November 1971, to formally recognize a group of nations facing the most acute developmental disadvantages.[6] This resolution endorsed the initial identification of 25 countries by the Committee for Development Planning (now the Committee for Development Policy), selected based on rudimentary indicators such as per capita gross domestic product below $100 annually and adult literacy rates under 20 percent.[7] The move addressed the empirical reality of structural impediments—low productive capacities, human resource deficiencies, and economic vulnerability—that perpetuated poverty traps in these states, distinct from broader developing economies.[2] Prior to 1971, international development assistance had often been distributed on an ad hoc basis influenced by political alliances rather than systematic assessment of need.[8] The LDC designation shifted focus toward objective, data-driven prioritization, aiming to galvanize coordinated global attention without presupposing aid as the sole pathway out of underdevelopment.[9] This rationale emerged from deliberations in the late 1960s, including UN reports highlighting post-independence stagnation in former colonies where resource endowments failed to translate into self-sustaining growth due to institutional and infrastructural deficits.[10] By institutionalizing the category, the UN sought to underscore causal factors of entrenched underdevelopment, such as limited diversification and exposure to external shocks, thereby facilitating targeted policies grounded in observable disparities rather than equitable distribution across all low-income nations.[11] The initial list included countries like Afghanistan, Mali, and Haiti, reflecting a consensus on the need for exceptional international measures to address vulnerabilities not adequately captured by general development frameworks.[12]Core Indicators: GNI, HAI, and EVI
The classification of least developed countries (LDCs) relies on three core quantitative indicators assessed by the United Nations Committee for Development Policy (CDP): gross national income (GNI) per capita, the Human Assets Index (HAI), and the Economic and Environmental Vulnerability Index (EVI). These metrics evaluate structural impediments to development, emphasizing low productive capacity, deficiencies in human capital accumulation, and exposure to exogenous shocks that perpetuate poverty traps through causal mechanisms such as limited investment, skill shortages, and institutional fragility rather than transient external factors alone.[2][3] For inclusion in the LDC category, a country must exhibit low performance across all three—GNI per capita below the inclusion threshold, HAI below its threshold, and EVI above its threshold—while graduation requires meeting enhanced thresholds in at least two criteria over two consecutive triennial reviews.[2] GNI per capita, calculated using the World Bank Atlas method to adjust for exchange rate fluctuations and population growth, serves as a direct proxy for a country's average economic output and productive capacity, excluding aid inflows to focus on domestically generated resources. The inclusion threshold stands at less than $1,088 (based on the 2024 review), reflecting economies with insufficient capital accumulation and technological adoption to sustain broad-based growth. For graduation, the standard threshold is $1,306 or higher, or $3,918 under an income-only pathway, underscoring that sustained income elevation signals improved structural productivity absent from aid-dependent models.[2][3] The HAI quantifies human capital endowments through a composite index averaging normalized scores from five indicators: prevalence of undernourishment, under-five mortality rate, maternal mortality ratio, gross secondary school enrolment ratio, and adult literacy rate. Low HAI scores (below the inclusion threshold, with graduation requiring 66 or above) highlight endogenous deficits in nutrition, health, and education, which causally constrain labor productivity and innovation by limiting workforce skills and demographic dividends. These components prioritize measurable outcomes over inputs, revealing institutional failures in public goods provision that perpetuate intergenerational poverty.[2][3][13] The EVI assesses structural vulnerability to economic and environmental shocks via two sub-indices: an exposure component (including remoteness, export concentration, and sectoral dependence on agriculture, forestry, or fisheries) and a shock proneness component (instability in exports and agricultural production, plus natural disaster victims per capita). High EVI scores (above the inclusion threshold, with graduation at 32 or below) indicate economies prone to volatility from undiversified structures and weak resilience, where poor governance amplifies shock impacts on growth rather than solely attributing instability to global events. This index, refined in 2015 to incorporate environmental factors, emphasizes that vulnerability stems from internal rigidities like small market size and policy shortcomings, not merely external dependencies.[2][3]Inclusion and Graduation Thresholds
A country qualifies for inclusion in the least developed countries (LDC) category by failing to meet the inclusion thresholds across all three core criteria—gross national income (GNI) per capita, human assets index (HAI), and economic vulnerability index (EVI)—as assessed by the United Nations Committee for Development Policy (CDP).[2] For the 2024 triennial review, these thresholds are set at a GNI per capita of $1,088 or below, an HAI of 60 or below, and an EVI of 36 or above, reflecting persistent low income, weak human development, and high exposure to external shocks.[14] This requirement ensures that only economies exhibiting structural underdevelopment across multiple dimensions are designated, prioritizing empirical indicators over temporary fluctuations or policy advocacy.[3] Graduation from LDC status requires a country to achieve the graduation thresholds for at least two of the three criteria in two consecutive triennial reviews by the CDP, thereby demonstrating sustained progress rather than isolated or aid-dependent gains.[15] The 2024 graduation thresholds are a GNI per capita of $1,306 or above, an HAI of 66 or above, and an EVI of 32 or below, with the higher margins for HAI and EVI (10% above and below the inclusion levels, respectively) designed to confirm resilience against regression.[4] An exception allows eligibility based solely on GNI if it reaches at least twice the graduation threshold ($2,612), though this has rarely been applied to emphasize comprehensive advancement.[5] These rules, refined in recent CDP updates to incorporate data on long-term trends excluding volatile aid inflows, aim to prevent premature exits that could expose economies to sudden loss of international support.[16] Upon a CDP recommendation meeting these thresholds, the United Nations General Assembly decides on graduation, typically effective after a minimum three-year preparation period to allow implementation of transition strategies.[3] Graduating countries retain LDC-specific international support measures, including trade preferences and aid commitments, for a smooth transition period of up to five years, as outlined in the Istanbul Programme of Action, to buffer against "graduation cliffs" such as abrupt tariff increases or reduced concessional financing.[5] This phased approach, informed by empirical reviews of past graduations showing vulnerability to external shocks post-status change, underscores causal links between sustained threshold compliance and viable post-LDC development.[17]Historical Development
Initial Identification in the 1970s
The 1970s economic landscape for many post-independence states in Africa, Asia, and the Pacific was characterized by persistent low growth and vulnerability, as these nations grappled with limited industrialization and heavy reliance on primary commodity exports amid global commodity price swings. The 1973 oil crisis, initiated by the OPEC embargo following the Yom Kippur War, quadrupled crude oil prices from approximately $3 to $12 per barrel, imposing severe balance-of-payments strains on non-oil-exporting low-income countries whose import dependencies amplified the shock's impact. This external pressure exacerbated internal low-income traps, where weak domestic manufacturing bases—often contributing less than 10% to GDP—and concentrated export profiles left economies susceptible to terms-of-trade deterioration without diversified revenue streams or robust fiscal buffers.[18][19][9] To address these acute disadvantages, the United Nations Committee for Development Planning (CDP), in its seventh session held in Geneva from March 29 to April 9, 1971, recommended initial criteria for identifying the "least developed among the developing countries," emphasizing empirical markers of structural underdevelopment over transient external factors. These included per capita gross domestic product below roughly $100 (using 1968 data), a manufacturing sector share of GDP under 10%, and human asset indicators such as caloric supply per capita below 2,200 calories daily and adult literacy rates under 20%. The framework highlighted internal constraints like inadequate human capital accumulation and failure to industrialize, which perpetuated dependence on undiversified primary exports and limited adaptive capacity to shocks, predating substantial international aid commitments.[20][21] The UN General Assembly formalized the category through Resolution 2768 (XXVI) on November 18, 1971, adopting the CDP's criteria and designating an initial list of 24 countries, including Afghanistan, Benin, Guinea, Haiti, Mali, Malawi, Nepal, Sudan, and Upper Volta (now Burkina Faso). This identification process prioritized empirical data on entrenched vulnerabilities, such as export concentrations exceeding 75% in a single commodity for many candidates, underscoring causal links between policy-induced structural rigidities and developmental stagnation.[9][12] In 1972, the CDP's eighth session from April 10 to 20 conducted the first comprehensive triennial review of the category, refining application of the criteria to ensure focus on countries with the most severe internal developmental deficits while urging special international measures like enhanced technical assistance to build export diversification and institutional capacities. This early analytical approach, grounded in available national accounts and demographic data, avoided over-reliance on aid as a panacea, instead signaling the need for domestic reforms to address root causes like low investment in human resources and productive sectors.[22][8]Evolution Through UN Conferences
The First United Nations Conference on the Least Developed Countries convened in Paris from 1 to 14 September 1981 and adopted the Substantial New Programme of Action, which urged donor countries to direct 0.15 percent of their gross national income toward official development assistance targeted at LDCs, prioritizing areas such as food security, agriculture, and basic infrastructure to address acute underdevelopment.[23] This initiative sought to counteract the structural vulnerabilities of LDCs but faced later criticism for emphasizing volume over conditionality, with empirical studies indicating that such aid often failed to generate sustained economic growth due to issues like fungibility and weak institutional absorption.[24] The Second Conference, held in Paris from 3 to 14 September 1990, assessed the era's debt crises and sluggish progress, adopting the Paris Declaration and Programme of Action that stressed export diversification, debt relief, and vulnerability to external shocks as key policy foci amid the 1980s' economic setbacks.[25] Building on this, the Third Conference in Brussels from 14 to 20 May 2001 produced the Brussels Programme of Action for 2001–2010, integrating LDC strategies with Millennium Development Goals, including pledges to halve extreme poverty by 2015; however, post-conference reviews revealed these targets were predominantly unmet, as LDC per capita income growth averaged below 2 percent annually and poverty persisted at over 40 percent in aggregate.[26][8] Subsequent conferences intensified emphasis on graduation pathways. The Fourth in Istanbul from 9 to 13 May 2011 endorsed the Istanbul Programme of Action for 2011–2020, aiming for at least half of LDCs to meet graduation criteria by 2020 through enhanced productive capacities and risk mitigation, yet only a handful advanced, underscoring causal factors like governance deficits and commodity dependence over aid inflows alone.[27] The Fifth, split between New York in March 2022 and Doha from 5 to 9 March 2023, adopted the Doha Programme of Action for 2022–2031, which extended support frameworks and deferred comprehensive category reviews to 2024 in recognition of stalled structural transformations despite prior commitments.[28] Across these summits, data consistently highlight LDCs' underperformance— with fewer than 10 graduations since 1981—attributable more to internal policy inertia than external aid shortfalls, per analyses prioritizing causal mechanisms over correlative inputs.[9][29]Reforms to Criteria Over Time
The United Nations Committee for Development Policy (CDP) has iteratively refined the LDC identification criteria since the category's inception to better capture structural impediments to development, shifting from simplistic income and literacy metrics toward composite indices that emphasize persistent vulnerabilities and human capital deficits. In 1991, the CDP introduced precursors to the Economic Vulnerability Index (EVI), incorporating factors such as export concentration and instability alongside population size to account for inherent risks faced by small and remote economies, moving beyond transient economic indicators to prioritize causal exposure to external shocks.[30] These early adjustments recognized that low income alone inadequately reflected barriers like geographic isolation, which empirical data showed amplified economic fragility independent of policy efforts.[8] By 2003, the criteria evolved further with the formal adoption of the Human Assets Index (HAI), replacing the earlier Augmented Physical Quality of Life index and incorporating under-five mortality rates and secondary school enrolment to quantify human capital deficiencies, informed by evidence that foreign aid inflows often yield limited growth without foundational investments in health and education.[30] The EVI was simultaneously refined to include remoteness and export instability metrics, enhancing predictive capacity for economic shocks as validated by longitudinal data on vulnerable economies.[8] Subsequent updates in 2012 fixed absolute thresholds for HAI (graduation at 66 points) and EVI (graduation below 32 points), decoupling them from relative distributions among developing countries to impose stricter, data-calibrated benchmarks that incentivize sustained reforms over marginal improvements.[30] Post-2012 refinements continued to prioritize causal realism, with 2017 additions to HAI of stunting prevalence and gender parity indices, and EVI expansions to encompass drylands exposure, addressing empirical gaps in measuring environmental and nutritional barriers that perpetuate low productivity cycles.[8] In 2024, the CDP raised GNI per capita thresholds (inclusion below $1,088, graduation above $1,306) and updated HAI to use lower secondary completion rates while refining EVI components like export market concentration and disaster victim data from the Sendai Framework, aiming to filter out countries reliant on temporary booms and compel institutional strengthening for verifiable progress.[30] These data-driven tweaks, applied in the 2024 triennial review, underscore a commitment to metrics that distinguish enduring structural frailties from reversible setbacks, though critics note that without corresponding enforcement of graduation, incentives for domestic reform may remain diluted.[31]Current Composition and Regional Breakdown
African LDCs
Africa accounts for the majority of the world's least developed countries, with 32 of the 44 UN-designated LDCs situated on the continent as of January 2025.[3] These nations predominantly feature low gross national income (GNI) per capita, averaging below $1,000 in recent years, alongside high human assets index (HAI) deficits and economic vulnerability index (EVI) scores driven by recurrent conflicts, climatic extremes, and structural fragilities.[32] Key population centers include the Democratic Republic of the Congo (over 100 million inhabitants), Ethiopia (approximately 120 million), and Sudan (around 48 million), which collectively represent significant shares of Africa's underdevelopment challenges.[33] The full roster of African LDCs comprises Angola, Benin, Burkina Faso, Burundi, Central African Republic, Chad, Comoros, Democratic Republic of the Congo, Djibouti, Eritrea, Ethiopia, Gambia, Guinea, Guinea-Bissau, Lesotho, Liberia, Madagascar, Malawi, Mali, Mauritania, Mozambique, Niger, Rwanda, São Tomé and Príncipe, Senegal, Sierra Leone, Somalia, South Sudan, Sudan, Togo, Uganda, United Republic of Tanzania, and Zambia.[34] These countries exhibit aggregate traits such as heavy commodity dependence, with 90% classified as reliant on primary commodity exports for over 60% of merchandise exports during 2018–2020, exposing them to price volatility and terms-of-trade shocks that empirical analyses link to stalled growth.[35] Resource-rich examples like Angola and the Democratic Republic of the Congo illustrate the resource curse phenomenon, where abundant natural endowments correlate with governance failures, including elite capture of rents and institutional weakening, rather than diversified economic progress.[36] Official development assistance (ODA) inflows remain critical, averaging around 3% of gross national income (GNI) across sub-Saharan African LDCs in recent data, though higher in fragile states like South Sudan and Somalia where aid constitutes 10–15% of GDP amid conflict and fiscal shortfalls.[37] EVI elevations stem from factors like drought in the Horn of Africa and insurgency in the Sahel, with over half of African LDCs scoring above the UN vulnerability threshold due to these exposures, compounding poverty traps through disrupted agriculture and displacement.[30] Poor governance metrics, including low scores on corruption perception indices for nations like Somalia and South Sudan, further hinder effective resource mobilization and investment, perpetuating cycles of aid dependence and commodity-led instability.[38]Asian and Pacific LDCs
The Asian and Pacific least developed countries (LDCs) comprise 11 nations as of January 2025: eight in Asia (Afghanistan, Bangladesh, Bhutan, Cambodia, Lao People's Democratic Republic, Myanmar, Nepal, and Timor-Leste) and three in the Pacific (Kiribati, Solomon Islands, and Tuvalu).[3][34] These countries exhibit greater diversity in economic trajectories compared to their African counterparts, with some demonstrating progress through export-oriented manufacturing while others remain mired in conflict-driven stagnation or geographic isolation. For instance, Bangladesh has achieved significant gross national income (GNI) per capita gains, reaching approximately $2,800 in 2023, primarily via ready-made garments exports, positioning it for graduation in November 2026.[4] In contrast, Myanmar's GNI per capita hovered around $1,200 in 2023 amid civil unrest following the 2021 military coup, underscoring aid-dependent traps exacerbated by political instability.[39] Human Assets Index (HAI) scores in Asian LDCs reflect moderate advancements in health and education metrics, averaging around 55-65 out of 100, driven by investments in primary schooling and maternal nutrition in nations like Nepal and Cambodia.[40] Nepal, for example, improved its HAI from 52 in 2018 to 60 by 2021 through expanded literacy programs, though persistent malnutrition affects 36% of children under five.[41] However, Economic and Environmental Vulnerability Index (EVI) scores remain elevated, often exceeding 50, due to structural factors such as landlocked status (e.g., Nepal, Lao PDR) and exposure to seismic activity or monsoons (e.g., Myanmar's cyclone-prone coasts).[42] This high EVI perpetuates fragility, as evidenced by Nepal's 2015 earthquake, which caused $10 billion in damages equivalent to 50% of GDP, highlighting causal links between geography and impeded capital accumulation.[39] Pacific LDCs, as small island micro-states, face acute vulnerabilities from their dispersed geography and low elevation, amplifying risks from sea-level rise and tropical cyclones.[43] Kiribati and Tuvalu, with populations under 120,000 each, register EVI scores above 70, reflecting near-total reliance on fisheries and remittances, which are disrupted by events like Cyclone Pam in 2015 that devastated 95% of Vanuatu's crops (a comparator Pacific state).[40] Solomon Islands exemplifies divergence, with modest HAI gains to 58 by 2021 via basic immunization coverage exceeding 80%, yet chronic disaster shocks—averaging one major event annually—constrain diversification beyond subsistence agriculture.[44] These empirical patterns reveal market-driven escapes in Asia's denser economies versus persistent traps in remote Pacific settings, where small scale limits economies of scale in infrastructure resilience.[39]| Country | Region | Key Vulnerability Factor | Recent HAI Score (approx.) | EVI Score (approx.) |
|---|---|---|---|---|
| Bangladesh | Asia | Flood-prone deltas | 62 | 52 |
| Myanmar | Asia | Political instability, cyclones | 58 | 55 |
| Nepal | Asia | Landlocked, earthquakes | 60 | 58 |
| Kiribati | Pacific | Sea-level rise | 55 | 72 |
| Tuvalu | Pacific | Isolation, storms | 54 | 75 |
Caribbean and Atlantic LDCs
As of October 2025, Haiti remains the sole least developed country (LDC) in the Caribbean and Atlantic regions, following the graduation of São Tomé and Príncipe from LDC status on December 13, 2024.[45][46] São Tomé and Príncipe, an Atlantic island state with a population of approximately 231,000, had exemplified the vulnerabilities of micro-insular economies, including extreme exposure to climate shocks and reliance on single commodities like cocoa exports, which comprised over 90% of its merchandise exports prior to graduation.[3] Haiti's persistence in the category highlights the persistent structural barriers amplified by its island geography, where limited landmass and remoteness constrain scale economies and inflate logistics costs by up to 20-30% compared to continental peers.[3] Haiti's gross national income (GNI) per capita of $1,536 falls well below graduation thresholds, reflecting subdued productivity amid geographic isolation that elevates import dependencies for energy and essentials, often doubling effective costs relative to larger economies.[47] Its Human Assets Index (HAI) score underscores deficits in nutrition, education, and health—key metrics penalized by insularity's barriers to scalable infrastructure and skilled labor mobility—while the Economic Vulnerability Index (EVI) exceeds 60 points, driven by structural factors like a 25% share of agriculture in GDP and recurrent exposure to cyclones, with over 90% of the population in disaster-prone zones.[48] Hurricanes, such as Matthew in 2016 which damaged 80% of crops, exemplify how insular positioning in the Atlantic hurricane belt amplifies EVI through rapid shock transmission, limiting resilience via small fiscal buffers and fragmented supply chains.[3] Despite preferential trade regimes like duty-free access to major markets, Haiti's export base shows minimal diversification, with apparel assembly (under U.S. preferences) and agricultural commodities like coffee and mangoes accounting for over 80% of goods exports, vulnerable to global price swings and weather disruptions inherent to island monocultures.[3] Tourism, a sector with theoretical insularity advantages, contributes less than 2% to GDP due to compounded risks from disasters and internal instability, perpetuating a cycle where geographic premiums hinder investment in higher-value services or manufacturing.[49] This profile illustrates how Atlantic and Caribbean insularity causally elevates vulnerability thresholds, sustaining LDC status through persistent high costs and shock amplification despite international supports.[3]Recently Graduated Countries
Since 2011, five countries have graduated from least developed country (LDC) status: the Maldives on January 1, 2011; Samoa on January 1, 2014; Equatorial Guinea on June 4, 2017; Vanuatu on December 4, 2020; and Bhutan on December 13, 2023.[3] [50] São Tomé and Príncipe followed in 2024, bringing the total number of graduates since the LDC category's establishment in 1971 to eight.[3] These transitions reflect sustained improvements in gross national income (GNI) per capita, human assets, and reduced economic vulnerability indices over consecutive triennial reviews by the UN Committee for Development Policy.[5] Post-graduation economic performance has shown mixed sustainability, often challenged by the phase-out of LDC-specific international support measures, including duty-free quota-free market access and enhanced official development assistance (ODA) commitments targeting LDCs.[51] While some graduates maintained GNI growth through resource exports or tourism, others faced stagnation or decline amid commodity dependence and external shocks, highlighting the limits of preferential benefits in fostering long-term structural resilience without domestic diversification. Temporary extensions of certain preferences, such as under the EU's Everything But Arms initiative for up to three years, mitigate immediate losses but do not fully offset reduced concessional financing.[51] The following table summarizes key post-2010 graduates, their graduation triggers, and initial GNI trajectories (World Bank Atlas method, current US dollars):| Country | Graduation Date | Pre-Graduation GNI (latest review) | Post-Graduation GNI Example | Notes on Outcomes |
|---|---|---|---|---|
| Maldives | January 1, 2011 | $5,436 (2009)[52] | $6,790 (2012) | Steady pre-graduation rise from tourism; post-graduation debt vulnerabilities emerged, but GNI held above thresholds amid global financial strains.[52] |
| Samoa | January 1, 2014 | $3,319 (2012, threshold ~$1,031)[53] | $4,006 (2016) | Modest growth sustained via remittances and services; exports dipped initially post-loss of preferences, but overall GNI tripled the threshold without reversal.[54] |
| Equatorial Guinea | June 4, 2017 | Oil-driven spike to ~$10,000+ (2014)[55] | Projected decline (2017 onward) | Resource depletion led to GDP contraction; heavy oil reliance exposed structural weaknesses, with limited diversification post-graduation.[56] |
| Vanuatu | December 4, 2020 | $2,913 (2020)[57] | Stagnant amid COVID (2021: ~$3,000) | Digital reforms aided pre-graduation; pandemic and cyclone shocks post-2020 hampered recovery, underscoring persistent vulnerability despite GNI stability.[58] |
| Bhutan | December 13, 2023 | ~$3,500+ (2021, with 7.5% avg. GDP growth 2010-2019)[59] | Early 2024: Growth ambitions amid grant phase-out | Hydropower and policy stability drove exit; post-graduation faces aid reduction risks, with plans for 10-fold GDP expansion by 2034 to counter lost concessional flows.[60] [61] |
