The Measurement of Inequality
U.S. income inequality
• Using quintiles to analyze income distribution
• Unequal Distribution of income
• Bottom fifth: <4% of all income
• Top fifth: nearly 50% of all income
• The Gini coefficient
0 = completely equal distribution
1 = all income goes to 1 person
• 2013 U.S. Gini coefficent = .481 5
