Calculating Lorenz Curve Area from Gini Coefficient and Area B
In a standard diagram used to measure income inequality, the area between the line of perfect equality and the income distribution curve is designated as 'Area A', and the area under the income distribution curve is 'Area B'. The inequality measure is calculated as the ratio of Area A to the total area under the line of perfect equality (Area A + Area B). If a country has an inequality measure of 0.4 and the value of Area B is 0.3, what is the value of Area A? Show your calculation steps.

A nation implements a series of economic policies that result in a more equal distribution of income among its population. When visualizing this change on a standard income distribution diagram, what is the resulting effect on the geometric areas used to calculate the primary measure of inequality, which is defined as the ratio of the area between the line of perfect equality and the income distribution curve (Area A) to the total area under the line of perfect equality (Area A + B)?

Comparative Income Inequality Analysis
In a diagram representing a country's income distribution, if the area between the line of perfect equality and the income distribution curve (Area A) is exactly equal to the area under the income distribution curve (Area B), then the resulting Gini coefficient is 1.0, indicating perfect inequality.
In a standard diagram used to measure income inequality, the total triangular area under the line of perfect equality is always 0.5. If a country's Gini coefficient is calculated to be 0.3, the numerical value of the area between the line of perfect equality and the country's income distribution curve is ____.
In a standard diagram used to visualize income distribution, match each geometric component or calculation with its corresponding description.
Two countries are analyzed using identical diagrams that plot the cumulative percentage of the population against the cumulative percentage of income. In these diagrams, the area between the line of perfect equality and the country's income distribution curve is labeled 'Area A', and the area under the income distribution curve is labeled 'Area B'. The total area under the line of perfect equality is the sum of these two areas (A + B).
- For Country X, Area A is 0.15.
- For Country Y, Area B is 0.20.
Based on this information and the standard formula where the inequality measure is the ratio A / (A + B), which statement is correct?

Calculating Lorenz Curve Area from Gini Coefficient and Area B
In a standard diagram used to visualize income distribution, the area between the line of perfect equality and the income distribution curve is labeled 'Area A', and the area under the income distribution curve is labeled 'Area B'. If Area B is equal to zero, this represents a state of perfect equality, and the corresponding inequality coefficient, calculated as A / (A + B), would be 0.
