Development Indicators and Inequality

Measuring and understanding development is fundamental to studying global governance and inequality. This lesson examines the indicators used to measure development, the theories that explain patterns of inequality, and the ongoing debates about what development means.

Key Definition: Development is the process of social and economic advancement that leads to improvements in people's quality of life. It is multidimensional, encompassing economic growth, health, education, political freedom, and environmental sustainability.

Economic Indicators

Gross Domestic Product (GDP)

GDP measures the total value of all goods and services produced within a country in a given year.

• GDP per capita (GDP divided by population) is commonly used to compare living standards between countries
• GDP (PPP) — Purchasing Power Parity adjusts for differences in the cost of living between countries, providing a more accurate comparison

Country	GDP per capita (nominal, 2023)	GDP per capita (PPP, 2023)
USA	~$76,000	~$76,000
UK	~$46,000	~$55,000
China	~$12,500	~$23,000
India	~$2,600	~$9,000
DRC	~$580	~$1,100

Limitations of GDP

• Does not measure income distribution — a country with high GDP per capita may have extreme inequality
• Ignores the informal economy — in many developing countries, a significant proportion of economic activity is unrecorded
• Does not account for environmental degradation — deforestation or pollution may increase GDP in the short term
• Fails to capture quality of life — health, education, leisure, social cohesion
• Does not distinguish between productive and destructive activity — spending on prisons and disaster recovery counts as GDP

Gross National Income (GNI)

GNI measures the total income earned by a country's residents, including income earned abroad, minus income earned domestically by foreign residents.

• GNI per capita is used by the World Bank to classify countries:
  • Low-income: $1,135 or less
  • Lower-middle-income: $1,136-$1,136−4,465
  • Upper-middle-income: $4,466-$4,466−13,845
  • High-income: $13,846 or more

Human Development Index (HDI)

The HDI, developed by Pakistani economist Mahbub ul Haq and published annually by the UNDP since 1990, provides a composite measure of development.

Components

Dimension	Indicator	Measurement
Health	Life expectancy at birth	Years
Education	Mean years of schooling + expected years of schooling	Years
Standard of living	GNI per capita (PPP)	US dollars

The HDI ranges from 0 to 1, with higher values indicating greater development.

HDI Rankings (2023 report)

Rank	Country	HDI	Category
1	Switzerland	0.967	Very High
4	UK	0.929	Very High
20	USA	0.921	Very High
75	China	0.788	High
134	India	0.644	Medium
192	South Sudan	0.385	Low

Strengths of the HDI

• Goes beyond purely economic measures to include health and education
• Enables comparison across countries using a single composite index
• Highlights that economic growth alone does not guarantee human development
• Has been widely influential in shaping development policy

Limitations of the HDI

• Uses national averages that mask inequalities within countries (gender, regional, ethnic)
• Only three dimensions — does not capture environmental sustainability, political freedom, or cultural factors
• Income is measured using GNI per capita, which has its own limitations
• Does not reflect security, governance quality, or human rights

Other Development Indicators

Gender Inequality Index (GII)

The GII measures gender-based disadvantage across three dimensions:

• Reproductive health — maternal mortality ratio, adolescent birth rate
• Empowerment — proportion of parliamentary seats held by women, secondary and higher education attainment
• Labour market — labour force participation rate

The GII ranges from 0 (full equality) to 1 (extreme inequality). Countries with the lowest GII (most equal) include Denmark, Norway, and Switzerland. Countries with the highest GII include Chad, Niger, and Yemen.

Multidimensional Poverty Index (MPI)

The MPI, developed by OPHI (Oxford Poverty and Human Initiative) and UNDP, measures poverty beyond income.

Ten Indicators across Three Dimensions:

Health	Education	Living Standards
Nutrition	Years of schooling	Cooking fuel
Child mortality	School attendance	Sanitation
		Drinking water
		Electricity
		Housing
		Assets

A person is identified as multidimensionally poor if they are deprived in at least one-third of these indicators. As of 2023, approximately 1.1 billion people across 110 countries were identified as multidimensionally poor.

Gini Coefficient

The Gini coefficient measures income or wealth inequality within a country on a scale of 0 to 1.

• 0 = perfect equality (everyone has the same income)
• 1 = perfect inequality (one person has all the income)

Country	Gini Coefficient (approx.)	Interpretation
Denmark	0.28	Very equal
UK	0.35	Moderate inequality
USA	0.39	Relatively unequal for a developed country
Brazil	0.49	High inequality
South Africa	0.63	Extreme inequality (one of the highest in the world)
