The Basics
- Simple definition: How the total income of a country is divided among its population; inequality measures the degree of unevenness.
- Core idea: Who gets how much of the economic pie?
- Think of it as: The slice sizes when the national income pie is shared.
What It Actually Means
Income distribution can be considered by size (how much individuals/households earn) or factor shares (labor vs capital). Inequality measures include: Lorenz curve (graphical), Gini coefficient (0=perfect equality, 1=perfect inequality), percentile ratios (top 10% vs bottom 10%). Causes: skill differences, education, inheritance, discrimination, globalization, technology, policy. High inequality can reduce growth, undermine social cohesion, and create political instability.
Example
Pakistan has high inequality – a small elite captures a large income share while many live in poverty. Urban-rural divides, regional disparities (Punjab vs Balochistan), and the informal economy contribute. Gini around 30-35 (moderate by regional standards but high absolutely).
Why It Matters (2026)
Inequality is rising globally, fueling populism and social tensions. The pandemic worsened it. Understanding distribution helps design fair tax and spending policies, and assess development progress.
