Global Development: Measuring and Comparing

Development is the process by which a country improves the economic and social wellbeing of its population. Development is multidimensional — it includes both economic growth (rising incomes, industrialisation, infrastructure) and social improvements (healthcare, education, gender equality, clean water, reduced poverty).

A country can have high economic output but still have large numbers of people in poverty (inequality). Conversely, some countries with relatively low incomes have invested heavily in education and healthcare, achieving better social outcomes than their GNI alone might suggest. This is why development cannot be measured by a single economic indicator.

Key terms:

• Economic development: increase in productive capacity and average wealth (GNI per capita is the primary measure)
• Social development: improvements in quality of life — health, education, access to services, freedom from poverty
• Sustainable development: development that meets present needs without compromising future generations' ability to meet their own needs (UN Brundtland Commission, 1987)

The Human Development Index (HDI) reflects this broader understanding: it combines GNI per capita, life expectancy, and years of education into a single composite score, recognising that development is more than just wealth.

Countries are grouped according to their level of economic and social development. The AQA specification uses three categories:

Classification	Definition	Characteristics	Examples
LIC (Low Income Country)	Countries with GNI per capita below approximately $1,135 (World Bank threshold)	Low incomes; high birth rates; high infant mortality; limited industrialisation; significant proportion of workforce in agriculture; frequently aid-dependent	Democratic Republic of Congo, Ethiopia, Afghanistan, Haiti, Mali
NEE (Newly Emerging Economy)	Countries experiencing rapid industrialisation and rising GNI, transitioning from LIC to HIC status	Rising manufacturing; growing middle class; improving health and education but with significant inequality; often high-profile BRICS or "Next 11" economies	China, India, Brazil, Nigeria, Mexico, Indonesia, South Africa
HIC (High Income Country)	Countries with GNI per capita above approximately $13,845 (World Bank threshold)	High incomes; low birth/death rates; long life expectancy; high literacy; strong service-sector economies; aging populations	UK, USA, Germany, Japan, Australia, South Korea

The choropleth below maps HDI across a sample of countries, showing the broad pattern of higher development in the global North and lower development across much of sub-Saharan Africa and South Asia.

These categories lie on a development continuum — not a binary division. Countries shift classification over time: South Korea was a low-income country in the 1960s and is now a high-income OECD member. China has moved from LIC to NEE status and parts of its population now live in HIC-equivalent conditions.

Gross National Income (GNI) per capita:

• Definition: the total value of goods and services produced by a country in one year, including income from overseas, divided by the total population
• Advantage: allows direct comparison between countries; widely available and consistently measured
• Limitations: an average figure that hides inequality; does not measure health, education, or quality of life; does not account for cost of living differences (purchasing power parity adjustments are needed)

GDP (Gross Domestic Product) (extra context — beyond AQA 8035 spec): the total value of goods and services produced within a country's borders, excluding overseas income. Similar to GNI but differs for countries with large overseas investment income.

Additional economic indicators used alongside GNI:

Indicator	What it measures	What it tells us
Birth rate (per 1,000 population per year)	Fertility and population growth	High birth rates correlate with poverty, low female education, and limited access to family planning
Death rate (per 1,000 population per year)	Mortality	Falling death rates reflect improved healthcare; very low rates indicate an ageing population
Infant mortality rate (deaths per 1,000 live births, under 1 year)	Child health and healthcare quality	Sensitive indicator of development — reflects nutrition, sanitation, maternal health, and access to medical care

Indicator	What it measures	Development relevance
Life expectancy (average years a person born today is expected to live)	Overall health and quality of healthcare	Ranges from ~87 years (Japan) to ~54 years (Central African Republic); reflects nutrition, disease burden, sanitation, and medical care
Literacy rate (% of adults who can read and write)	Educational attainment	Low literacy indicates underinvestment in education; limits economic productivity and democratic participation
Access to safe water (% of population with clean drinking water)	Sanitation and infrastructure	Lack of clean water causes disease (cholera, typhoid, diarrhoea) and forces women and children to spend hours each day collecting water
People per doctor	Healthcare access and provision	Fewer people per doctor indicates better healthcare access; in the UK the ratio is ~1:500; in some LICs it exceeds 1:20,000

Comparing indicators:

Country	GNI per capita (approx.)	Life expectancy	Infant mortality (per 1,000)	Literacy rate
UK (HIC)	$48,000	81 years	4	99%
Brazil (NEE)	$9,000	75 years	14	94%
Nigeria (NEE)	$2,200	63 years	56	62%
DRC (LIC)	$590	61 years	77	77%

(Figures are approximate and vary by source and year.)

The Human Development Index (HDI) was developed by the United Nations Development Programme (UNDP) in 1990. It is the most widely used composite development measure.

How HDI is calculated:

Dimension	Indicator	Weight
Long and healthy life	Life expectancy at birth	1/3
Knowledge	Mean years of schooling + expected years of schooling	1/3
Decent standard of living	GNI per capita (PPP, $)	1/3

HDI scores range from 0 (least developed) to 1 (most developed). Countries are classified as:

• Very high human development: HDI ≥ 0.800 (e.g. Norway: 0.966, UK: 0.940)
• High human development: 0.700–0.799 (e.g. Brazil: 0.760)
• Medium human development: 0.550–0.699 (e.g. Morocco: 0.683, Bangladesh: 0.661)
• Low human development: < 0.550 (e.g. Nigeria: 0.548, Niger: 0.394)

Advantages of HDI over GNI alone: captures health and education; reveals inequality between countries with similar GNI (e.g. Cuba has HDI of 0.764 despite low GNI — reflecting heavy investment in healthcare and education under its system).

Limitations of HDI: still an average — hides inequality within countries; does not capture gender equality, sustainability, or political freedom.

The Demographic Transition Model (DTM) shows how birth rates and death rates change as a country develops. The link between DTM stage and development level is a direct spec requirement. The graph below shows the two rates and the resulting total population across the five stages.

Population grows fastest in Stages 2 and 3, when death rates have fallen but birth rates remain high. In Stage 5 the birth rate drops below the death rate and total population begins to decline.

DTM Stage	Birth rate	Death rate	Population growth	Development level	Examples
Stage 1	High	High	Slow (rates balance)	Pre-industrial; LIC	No countries today; historical
Stage 2	High	Falling	Rapid increase	Early LIC/NEE; agricultural improvements, basic healthcare	Sub-Saharan Africa (some areas), Afghanistan
Stage 3	Falling	Low	Slowing increase	NEE; urbanisation; rising female education; contraception	India, Nigeria, Mexico
Stage 4	Low	Low	Slow growth or stable	HIC; urbanised; high female education; healthcare	UK (historically Stage 4); USA, Brazil
Stage 5	Very low	Low	Decline	HIC with ageing population	Germany, Japan, South Korea, some Western European countries

Why does development reduce birth rates?

• Urban families need fewer children (children are an economic cost, not a labour asset)
• Rising female education and employment opportunities
• Better access to family planning and contraception
• Falling infant mortality reduces the incentive to have many children as "insurance"

Causes (brief overview — explored in depth in the Development Gap lesson):

Category	Examples of causes
Physical	Tropical disease burden (malaria); drought and crop failure; landlocked geography; lack of fertile land or natural resources
Economic	Primary commodity dependence; unequal trade rules (WTO); debt; limited FDI; TNC profit repatriation
Historical	Colonial extraction; suppression of local industry; arbitrary borders; institutional weaknesses inherited from colonial period

Consequences of uneven development:

Disparities in wealth and health:

• GNI per capita varies from ~$590(DRC)to$87,000 (Luxembourg) — a 150× difference
• Life expectancy ranges from ~54 years in some LICs to ~87 years in Japan
• Child mortality: in HICs, fewer than 5 in every 1,000 children die before age 5; in some LICs, more than 100 per 1,000 die before age 5
• Access to clean water, sanitation, electricity, and healthcare differs dramatically between LICs and HICs

International migration:

• Economic inequality is a primary driver of international migration — people move from LICs and NEEs to HICs in search of higher wages, better opportunities, and safety
• Economic migrants leave countries with high unemployment, low wages, or limited opportunities for countries with higher wages and more job opportunities (e.g. Sub-Saharan Africans migrating to Europe; South Asians migrating to Gulf states)
• This creates a brain drain — skilled workers (doctors, engineers, teachers) emigrate, leaving LICs depleted of human capital precisely when it is most needed
• Remittances sent home by migrants contribute significantly to LIC GDPs (e.g. remittances to Haiti amount to over 30% of GDP)

1. Confusing GNI and GDP

GNI includes income earned abroad by a country's nationals. GDP only includes production within the country's borders. For most exam purposes, GNI per capita is the correct economic development indicator to use — the spec names GNI, not GDP. Using GDP when GNI is asked loses precision.

2. Treating development as only economic

Development includes both economic growth and social improvements. A complete definition of development mentions at least one economic indicator (GNI per capita) and one social indicator (e.g. life expectancy, literacy, access to healthcare). The HDI is the composite measure that captures this.

3. Stating infant mortality measures the number of babies born

Infant mortality rate measures deaths of children under one year of age, expressed per 1,000 live births. It does not measure birth rate. It is one of the most sensitive indicators of development because it reflects healthcare quality, maternal nutrition, sanitation, and poverty simultaneously.

4. Confusing NEE with HIC or LIC

An NEE is a country that is industrialising and growing rapidly but has not yet reached high-income status. China and Brazil are NEEs (or have recently been classified as upper-middle-income), not HICs. The UK, USA, and Japan are HICs. Niger and DRC are LICs. Check whether the question specifies a category before writing your answer.

5. Describing HDI components incorrectly

HDI combines three dimensions: life expectancy, education (years of schooling), and GNI per capita. Students often incorrectly list literacy rate (not in HDI), GDP (not in HDI — GNI is used), or forget to mention education. Memorise the three components exactly.
