Developing Countries: Classifications, Characteristics, and Global Challenges

A developing country is generally defined as a nation with a less-developed industrial base and a lower Human Development Index (HDI)—a composite statistic of life expectancy, education, and per capita income—relative to developed countries. However, this definition is not universally agreed upon, and there is often debate regarding which specific nations fit into this category.

In recent years, terminology has shifted to avoid outdated "us versus them" narratives. In 2015, the World Bank announced it would phase out the "developing/developed world" descriptor in favor of data aggregations based on regions and income groups. Consequently, terms like Global South, low-and middle-income country (LMIC), and newly emerging economy (NEE) are frequently used as alternatives.

  • Diverse Metrics: Countries are classified using various criteria, including gross national income (GNI), financial stability, and social development.
  • World Bank Groups: Economies are divided into four main income groups: high, upper-middle, lower-middle, and low-income.
  • IMF Focus: The International Monetary Fund (IMF) prioritizes financial integration and stability over social development metrics.
  • Common Hurdles: Many developing nations face shared challenges such as urban slums, inadequate sanitation, and high vulnerability to climate change.
  • Sub-groupings: Specific categories include Least Developed Countries (LDCs), Landlocked Developing Countries, and Small Island Developing States.

Different international organizations use distinct methodologies to categorize the world's economies, leading to overlapping or sometimes conflicting lists.

By Income Level (World Bank)

The World Bank classifies economies based on gross national income per capita. This system provides a snapshot of economic capacity across four tiers: high-income, upper-middle-income, lower-middle-income, and low-income countries.

By Market Growth and Industrialization

Economies are also categorized by their stage of industrialization and the size of their capital markets. This hierarchy typically includes:

  • Newly Industrialized Countries: Nations experiencing rapid industrial growth.
  • Emerging Markets: Economies becoming more integrated into global markets.
  • Frontier Markets: Smaller, less liquid markets than emerging ones.
  • Least Developed Countries: Nations with the lowest indicators of socioeconomic development.

By Financial Integration (IMF)

The IMF focuses on financial stability and integration. Notably, the adoption of the Euro has led the IMF to upgrade several European countries to "developed economy" status based on financial integration, regardless of other social development factors.

Geographic and Special Designations

Geography often dictates economic opportunity. Landlocked Developing Countries often face inherent economic disadvantages due to a lack of direct sea access. Additionally, the UNCTAD uses the terms "North" (developed) and "South" (developing/least developed) for statistical convenience, though these do not necessarily reflect a judgment on a country's specific stage of development.

Economic classification of the world's countries and territories by the UNCTAD in 2023: "North" refers to the developed economies, highlighted in blue; and "South" to the developing and least developed economies, highlighted in red. UNCTAD notes that "the designations "developing" and "developed" are intended for statistical convenience and do not necessarily express a judgement about the stage reached by a particular economy in the development process".[48][49][50]

Common Characteristics and Challenges

While every nation is unique, many developing countries share systemic challenges rooted in history, geography, or governance.

Public Health and Sanitation

Healthcare systems in developing regions often struggle with a dual burden: the persistence of neglected tropical diseases and the rise of non-communicable diseases. Poor WASH (Water, Sanitation, and Hygiene) infrastructure leads to unsafe drinking water and poor hygiene, further compromising public health.

Environmental and Climate Risks

Developing nations are often disproportionately vulnerable to climate change. Challenges include severe air and water pollution, as well as the reliance on inefficient energy sources. Indoor air pollution remains a significant health risk in these regions.

Social and Political Issues

Many developing countries face systemic social hurdles, including the prevalence of urban slums and high rates of violence against women. Governance issues, particularly corruption, can hinder economic progress, necessitating special laws and increased transparency to protect the national economy.

Demographics and Human Capital

Population growth rates and fertility rates vary widely across the Global South, impacting the demand for education and healthcare. However, these regions also possess significant Human Capital opportunities through investments in education and workforce development.

Frequently Asked Questions

What is the difference between a developing country and an emerging market?

While often used interchangeably, "developing country" is a broad term encompassing social and industrial development, whereas "emerging market" refers specifically to the economy's growth and its integration into global capital markets.

Why is the World Bank phasing out the term "developing world"?

The World Bank believes the categorization has become less relevant and can perpetuate outdated stereotypes. They now prefer to use data aggregations based on specific income groups and regions.

What is the Human Development Index (HDI)?

The HDI is a composite measure used to rank countries by looking at life expectancy, education (mean and expected years of schooling), and per capita income.

How does being landlocked affect a developing country?

Landlocked Developing Countries often face higher trade costs and economic disadvantages because they lack direct access to maritime trade routes, making them dependent on neighboring countries for port access.

What are the BRICS countries?

BRICS is an organization consisting of ten countries that belong to the "emerging markets" group, representing some of the fastest-growing economies in the developing world.

ISBN 978-1-56549-174-8. among the countries of the Global South, there are also some common characteristics. First and foremost is a continuing struggle for secure livelihoods amidst conditions of serious poverty for a large number of people in these nations. For many, incomes are low, access to resources is limited, housing is inadequate, health is poor, educational opportunities are insufficient, and there are high infant mortality rates along with low life expectancy. ... In addition to the attributes associated with a low standard of living, several other characteristics are common to the Global South. One is the high rate of population growth and a consequent high dependency burden — that is, the responsibility for dependents, largely young children. In many countries almost half the population is under fifteen years old. This population composition represents not only a significant responsibility, but in the immediate future, it creates demands on services for schools, transport, new jobs, and related infrastructure. If a nation's gross national income (GNI) is growing at 2 percent a year and its population is growing at that rate too, then any gains are wiped out.

In much debate on cities in the Global South, infrastructure is synonymous with breakdown, failure, interruption, and improvisation. The categorization of poorer cities through a lens of developmentalism has often meant that they are constructed as "problem". These are cities, as Anjaria has argued, discursively exemplified by their crowds, their dilapidated buildings, and their "slums".
