IB Economics HL 3.4.3 Measuring inequality
Students practise sketching, labelling and interpreting Lorenz curves—and linking shifts to Gini coefficient changes—to assess income inequality trends.
How this is tested
- sketch a Lorenz curve after transfers, labelling axes and the line of perfect equality
- explain a higher Gini by showing the Lorenz curve bowing further from perfect equality
- construct a Lorenz curve from cumulative quintile data with correct axes and diagonal
