Income inequality — Economics, 11–13 years
People and households can receive very different incomes, even in the same society. Measuring the gap helps describe the pattern, while asking why it exists and what is fair requires careful evidence and judgement.
Different shares of income
Income inequality means that money received over a period is not shared equally among people or households. It is about the size of incomes, not automatically about whether someone is kind, hardworking or deserving. A society can have higher average income and still have a large gap between groups.
Why measure the gap?
Averages can hide important differences. If one person receives €90 and nine people receive €10, the average is €18, but most people do not receive €18. Comparing groups helps reveal who has more or less income and supports questions about access to housing, education, health and other opportunities.
Finding a mean and a gap
Five households receive monthly incomes of €900, €1,100, €1,200, €1,300 and €2,500. Add them: €7,000. Divide by five to find the mean: €1,400. The highest income is €1,600 above the lowest. The mean is useful, but it does not show that one household receives much more than the others.
Unequal is not automatically unfair
It is reasonable to feel that unequal incomes must be unfair, especially when some people cannot afford essentials. But inequality describes a difference; fairness is a judgement about causes, rules and results. A careful discussion asks how the gap arose and whether people have genuine chances, rather than deciding from one number alone.
Reading a local report
A news report might say that a town’s average income rose while many families still struggle with rent and food. Looking at the average alongside the lowest and highest incomes gives a clearer picture. This helps people ask better questions about jobs, services and decisions that affect their community.
