What does development mean?

Development is change that can improve people’s lives. Income is one part. Health, education, freedom and access to services also matter.

An indicator is a measure that gives us evidence about one part of life. Use several indicators to build a clearer picture.

IndicatorWhat it measuresWhat to watch for
GNI per personA country’s income divided by its populationAn average can hide large income gaps.
Life expectancy at birthExpected years of life under current mortality ratesIt is a population measure, not a prediction for one person.
HDIA combined measure of health, education and incomeOne score still hides differences within a country.

GNI means gross national income. HDI means Human Development Index. UNDP’s HDI uses life expectancy, years of schooling and GNI per person. It does not include every part of wellbeing. Read UNDP’s definition

Two places, one average

In an invented village, five annual incomes are 2, 2, 2, 2 and 22 thousand units. The mean is 6 thousand units, but four people earn only 2 thousand. The median is 2 thousand.

Calling everyone “well off” because of the mean would miss this gap. Check who benefits, not just whether the national average rises.

Check you’ve got it

Two countries have similar GNI per person. Must their HDI be the same?

Check your answer

No. Health and education can differ. Compare the indicators and their dates before explaining the contrast.

Part 1 of 3

Choose a suitable indicator

Development includes income, health, education and opportunity. GNI per person describes an average income measure; life expectancy and educational indicators answer different questions.

HDI combines health, education and income dimensions. No single indicator reveals every regional or household difference.

Worked example

Fictional incomes of 1, 1, 1, 1 and 16 units have mean 4 and median 1. The mean does not describe the typical household well in this unequal distribution.

Common mistake: A national average is not an amount received by every resident.

Trace industrial and trading change

Primary, secondary and tertiary activities connect through production and services. Factories can create jobs and make goods to sell abroad. They may also depend on imported parts and decisions made in another country.

A transnational corporation (TNC) operates in more than one country. TNC investment, trade and aid can all affect development. Check training, taxes, working conditions and environmental effects as well as how much is produced.

Worked example

A fictional export sells for 100 units, with 60 spent on imported components. The remaining 40 is not automatically worker pay; it also covers other domestic costs and returns.

Common mistake: Gross export value is not the same as income retained locally.

Part 3 of 3

Evaluate a development strategy

Tourism, new businesses, fair trade and better services can help places develop. Debt relief can reduce what a country must repay. Who benefits depends on who can take part, how decisions are made and whether demand lasts.

Use Nigeria’s national evidence and Rwanda’s tourism evidence at their own scales. A project outcome cannot establish national equality.

Worked example

Fictional household spending rises from 100 to 110 while prices rise from 100 to 120. Its purchasing-power index is 110 ÷ 120 × 100 = 91.7, below the baseline.

Common mistake: Higher nominal income can accompany lower purchasing power.

The shading represents a percentage of households, not a total. Each class includes its lower boundary and excludes its upper boundary: a value of 20 belongs in 20–30, not 10–20.
