Graphical representation showing cumulative income distribution among households, highlighting disparities between population segments. Gini Coefficient
Numerical measure quantifying income inequality, ranging from 0 for perfect equality to 1 for complete inequality. Quintile
Population segment representing 20% of households, used to analyze income distribution from poorest to richest. Cumulative Percentage
Total value obtained by sequentially adding percentages, applied to both households and income in inequality analysis. Line of Equal Distribution
Diagonal graph line depicting a scenario where every population segment receives an equal share of income. Income Inequality
Disparity in income allocation among population groups, visualized through curves and coefficients. Complete Inequality
Situation where all income is concentrated in a single household, leaving others with none. Area A
Region between the Lorenz curve and the line of equal distribution, used in calculating the Gini coefficient. Area B
Region below the Lorenz curve and above the horizontal axis, essential for Gini coefficient computation. Horizontal Axis
Graph axis representing cumulative percentage of households, progressing from poorest to richest. Vertical Axis
Graph axis indicating cumulative percentage of income, used to plot income distribution. Line of Unequal Distribution
Graph line illustrating extreme income concentration, where only one household receives all income. Ratio
Mathematical relationship comparing two areas on the graph, forming the basis for the Gini coefficient. Slope
Steepness of a graph line, with a slope of 1 indicating perfect equality in income distribution. Distribution
Pattern of income allocation across population segments, central to understanding economic inequality.
