The 'Lorenz curve' in public health is used to measure:
- A Maternal mortality trends over time
- B Equity and inequality in health resource distribution (associated with Gini coefficient) ✓
- C Population pyramid for age-sex distribution
- D Incidence of notifiable communicable diseases
Correct answer: B. Equity and inequality in health resource distribution (associated with Gini coefficient)
Explanation
The Lorenz curve graphically represents income or resource inequality — the x-axis shows the cumulative percentage of the population and the y-axis shows the cumulative percentage of income/resource share. The Gini coefficient is the ratio of the area between the Lorenz curve and the line of equality to the total area below the equality line (ranges 0 to 1; 0 = perfect equality, 1 = perfect inequality). It is widely used in health equity analysis.
