Learning goals
Learners will
- Explain how human wellbeing is defined and measured.
- Interpret development indicators, including the HDI.
- Explain spatial variations in wellbeing within Australia and between countries.
Success looks like
- I can name the three dimensions of the Human Development Index.
- I can explain the limits of using GDP or GNI per capita alone.
- I can describe a spatial variation in wellbeing within Australia and its causes.
The big idea
Wellbeing is about quality of life: health, education, income, safety, environment, community and having a say in decisions. Geographers study how and why wellbeing varies from place to place.
Economic indicators like GNI per capita show average income but have limits. An average can hide inequality, and income does not measure health, education or happiness.
The United Nations Development Programme's Human Development Index (HDI) combines three dimensions: a long and healthy life (life expectancy), knowledge (years of schooling) and a decent standard of living (GNI per capita). Scores range from 0 to 1. Australia is among the countries with very high human development.
Other measures include access to clean water and sanitation, literacy rates, infant mortality and measures of happiness and life satisfaction.
There are large spatial variations within countries too. In Australia, people in major cities on average have better access to health services than people in remote areas.
Australian data show gaps in some measures of health and education between Aboriginal and Torres Strait Islander people and other Australians. These gaps are linked to the long-term effects of colonisation, dispossession and discrimination, as well as access to services. The National Agreement on Closing the Gap (2020) was developed in partnership with First Nations community-controlled organisations, recognising that First Nations-led solutions are essential.
When using data, geographers ask: what does this indicator measure, what does it miss, and whose idea of wellbeing does it reflect?
Worked examples
Interpreting HDI
Country A has an HDI of 0.95 and Country B has an HDI of 0.55. What does this suggest?
- HDI ranges from 0 to 1; higher is better.
- Country A likely has higher life expectancy, more years of schooling and higher incomes.
- But the HDI is an average and may hide inequality within each country.
Answer: Country A has much higher average human development, though inequalities may exist within both.
Limits of an average
Five people earn $20,000, $25,000, $30,000, $35,000 and $390,000. What is the mean income, and why is it misleading?
- Total: 20,000 + 25,000 + 30,000 + 35,000 + 390,000 = 500,000.
- Mean: 500,000 ÷ 5 = 100,000.
- Four of five people earn far less than $100,000; one high income pulls the mean up.
Answer: Mean = $100,000, which misrepresents most people's incomes.

Answer guide for parents
Which is NOT one of the three dimensions of the HDI?
Number of cars — The HDI uses health, education and income.
What is a limitation of GNI per capita?
It is an average that can hide inequality — Averages can hide large differences between people.
HDI scores range between…
0 and 1 — HDI values range from 0 to 1.
Which organisation publishes the HDI?
The United Nations Development Programme — The UNDP publishes the HDI.
Which is an example of spatial variation in wellbeing?
Remote areas having less access to health services than cities — Differences between places are spatial variations.
What does the abbreviation HDI stand for? Human Development ____.
Index — HDI stands for Human Development Index.
Incomes are $40,000, $50,000 and $60,000. What is the mean income in dollars?
50000 — (40,000 + 50,000 + 60,000) ÷ 3 = 50,000.
The average number of years a person is expected to live is called life ____.
expectancy — Life expectancy is a key health indicator.
Watch out for
- Higher income does not automatically mean higher wellbeing; health, education, safety and community also matter.
- National averages can hide large differences between regions and groups within a country.
- Gaps in wellbeing indicators are sometimes wrongly blamed on individuals or cultures; geographers examine historical, structural and access-related causes.
Tips for parents
- Discuss inequality sensitively, avoiding deficit language about any group.
- Use official data sources such as the ABS and UNDP for accurate figures, and note the year of the data.
- For First Nations wellbeing, seek perspectives from First Nations community-controlled organisations, which describe their own priorities and strengths.
Go further
- Graph HDI against life expectancy for ten countries and describe the relationship.
- Map an indicator such as access to GPs across regions of your state.
- Design your own wellbeing index and justify the indicators you chose.
