1. Classification Methods for Economiesβ˜…β˜…β˜†β˜†β˜†β± 5 min

Countries are commonly classified into developed and developing groups based on a range of economic and social indicators. The most widely used traditional classification is based on gross national income (GNI) per capita, adjusted for purchasing power parity (PPP) to account for cross-country price differences.

πŸ“˜ Definition

GNI per capita (PPP adjusted)

Total income earned by a country's residents, divided by population, adjusted for differences in the cost of living between countries

Example:

In 2024, the World Bank defines high-income economies as those with GNI per capita above $13,845, where most developed economies fall.

A more modern composite measure is the Human Development Index (HDI), which combines income with health and education outcomes to capture broader development progress beyond just income.

πŸ“ Worked Example

A country has a GNI per capita of $15,000, an average life expectancy of 62 years, and mean years of schooling of 4.2 years. How would classification differ between GNI and HDI criteria?

  1. 1

    Step 1: Assess GNI-based classification

  2. 2

    The 2024 World Bank high-income threshold is $13,845. This country's GNI per capita meets the traditional threshold for developed status.

  3. 3

    Step 2: Assess HDI-based classification

  4. 4

    HDI defines very high human development (developed status) as scores above 0.80. Low life expectancy and schooling would give this country an HDI score below 0.7, classifying it as developing.

  5. 5

    Step 3: Conclusion

  6. 6

    Classification depends entirely on the indicator used: GNI alone classifies it as developed, while HDI classifies it as developing.

Exam tip:

Always check if a question asks for income-based or broader development-based classification before answering.

2. Key Characteristics of Developing Economiesβ˜…β˜…β˜…β˜†β˜†β± 6 min

While there is significant heterogeneity between developing economies (from upper-middle income countries like Brazil to low-income countries like Niger), they share several common characteristics.

  • Lower average incomes and higher rates of absolute poverty

  • Higher population growth and higher youth dependency ratios

  • Lower literacy rates, lower school enrolment, and poorer health outcomes

  • Dependence on primary sector production and agricultural exports

  • Less developed infrastructure and weaker institutional frameworks

  • Higher rates of informal employment and underemployment

πŸ“ Worked Example

Explain how dependency ratios differ between developed and developing economies.

  1. 1

    Step 1: Define dependency ratio: the share of non-working age population (under 15 or over 64) per 100 working age people.

  2. 2

    Step 2: In developing economies, high historical birth rates create a large share of population under 15, leading to high youth dependency. For example, Niger has a dependency ratio of 110 dependents per 100 working age people.

  3. 3

    Step 3: In developed economies, lower birth rates and aging populations lead to higher old-age dependency, but total dependency ratios are usually much lower (around 50-60 dependents per 100 working age people).

3. Key Characteristics of Developed Economiesβ˜…β˜…β˜…β˜†β˜†β± 5 min

Developed economies are defined by high levels of productivity across all sectors, advanced human capital, and strong institutional frameworks. Most are post-industrial, with the service sector accounting for 70% or more of total output.

  • High GNI per capita and HDI scores above 0.8 (very high human development)

  • Low rates of absolute poverty and well-developed social safety nets

  • Aging populations and low birth rates

  • Dominated by high-value services and knowledge-based manufacturing

  • Well-developed physical and digital infrastructure, strong rule of law

  • Low shares of informal employment

πŸ“ Worked Example

Why is the service sector share of output much larger in developed economies than in developing economies?

  1. 1

    Step 1: As incomes rise, demand for services (healthcare, education, finance, entertainment) increases faster than demand for goods, which are more income inelastic.

  2. 2

    Step 2: Productivity improvements in agriculture and manufacturing reduce the number of workers needed in these sectors, shifting employment and output to services.

  3. 3

    Step 3: Many developed economies outsource low-value manufacturing to developing economies, further increasing the service share of domestic output. This explains the large sectoral difference between the two groups.

4. Limitations of Binary Classificationβ˜…β˜…β˜…β˜…β˜†β± 6 min

Grouping all countries into just two broad categories (developed and developing) has significant limitations that you must be able to evaluate for CIE exams.

  • Many middle-income countries fall between the two categories and do not fit neatly into either group

  • Some countries have high income but low human development (e.g. resource-rich states), leading to conflicting classifications

  • Classifications become outdated quickly as countries grow and develop

  • Binary classification ignores major differences in economic structure, geography and politics between countries in the same group

πŸ“ Worked Example

Explain why Saudi Arabia does not fit neatly into the developed/developing binary classification.

  1. 1

    Step 1: Saudi Arabia has a GNI per capita of over $40,000, well above the high-income threshold, so it is classified as developed by income criteria.

  2. 2

    Step 2: It has lower scores for education outcomes, life expectancy and gender equality than most developed economies, giving it an HDI score just above the 0.8 threshold for very high development.

  3. 3

    Step 3: Its economy remains heavily dependent on oil exports, with a far less diversified industrial base than most developed economies. This demonstrates how binary classification can be misleading.

Exam tip:

Always include evaluation of classification limitations when asked to discuss the developed/developing distinction to access top marks.

5. Common Pitfalls

Wrong move:

Assuming all developing economies are low-income and homogeneous

Why:

There is enormous variation between developing economies, from upper-middle income countries to low-income fragile states. Generalising leads to incorrect evaluation.

Correct move:

Acknowledge heterogeneity within groups and use specific examples to illustrate variation when answering questions.

Wrong move:

Only using GNI per capita to classify countries

Why:

CIE examiners expect recognition that development is broader than just income, so only using income will lose evaluation marks.

Correct move:

Always mention both income-based and composite measures like HDI when classifying economies.

Wrong move:

Confusing dependency ratio with population growth rate

Why:

Many students mix the two terms up: an aging developed economy can have low population growth but a high total dependency ratio.

Correct move:

Remember dependency ratio measures the share of non-working age population, regardless of current population growth.

Wrong move:

Claiming all developing economies have aging populations

Why:

This reverses the common trend: most developing economies have young populations, while most developed economies have aging populations.

Correct move:

Recall higher birth rates in developing economies create higher youth dependency, while developed economies have higher old-age dependency.

Wrong move:

Accepting binary classification as perfectly accurate

Why:

CIE expects evaluation of the limitations of grouping countries into just two categories, not just acceptance of the distinction.

Correct move:

Always evaluate the limitations of binary classification when asked to discuss the developed/developing distinction.

What's Next

Understanding the characteristics of developed and developing economies is the foundation for studying the causes of and barriers to economic development, the core focus of this CIE A-Level unit. The characteristics outlined here explain why many developing economies face specific challenges like poverty traps, population pressure, and primary product dependence, which we explore in subsequent topics. This classification also underpins analysis of the role of foreign aid, trade, and government intervention in promoting inclusive development. Building on this topic, you will next explore how to measure development, the difference between economic growth and development, and the factors that drive long-term development progress.
