Gini Coefficient
The Gini coefficient is a numerical measure of income or wealth distribution inequality. It ranges from 0 (perfect equality where everyone has the same income) to 1 (perfect inequality where one person has all income).
Real World
South Africa has one of the world's highest Gini coefficients (around 0.63), a direct legacy of apartheid-era wealth concentration that persists decades after democracy was established.
Exam Focus
Always contextualise a Gini figure by comparing it to another country or global average — raw numbers alone score fewer marks.
