Question 3

The Gini coefficient, ranging from 0 to 1, is a key statistical measure of income inequality. If a country observes its Gini coefficient rising from 0.30 to 0.45 over a ten-year period, what is the most appropriate interpretation of this change in socio-economic terms?

Accepted Answer

B. There has been an increase in income disparities, indicating a wider gap between the rich and the poor. — The correct answer is B. A higher Gini coefficient indicates greater income inequality. Therefore, a rise from 0.30 to 0.45 signifies a worsening income distribution and a wider gap between the rich and the poor. Options A and D are incorrect as they suggest an improvement in equality or effective welfare programs, which would typically lead to a decrease in the Gini coefficient. Option C is incorrect because the Gini coefficient measures relative inequality, not the absolute level of national income or widespread absolute poverty.

Answer

A. The country has successfully implemented policies that led to a more equitable distribution of wealth.

Answer

C. The overall national income has significantly decreased, leading to widespread absolute poverty.

Answer

D. The government's social welfare programs have become highly effective in reducing economic disparities.
