The Rich/Poor Ratio as a Measure of Inequality in the 2020 Distribution

Comparing National Income Inequality

In a hypothetical country, the average annual income for the wealthiest 10% of the population is $240,000, while the average annual income for the poorest 10% of the population is $12,000. Based on this information, what is the country's rich/poor ratio?

Consider a country where the rich/poor ratio, defined as the average income of the richest 10% divided by the average income of the poorest 10%, is currently 15. A new government policy is implemented that results in a 5% increase in the average income of the poorest 10% of the population, while the average income of the richest 10% remains unchanged. What will be the effect on the country's rich/poor ratio?

Country A and Country B both have a rich/poor ratio of 10. In Country A, the average income for the richest 10% of the population is $100,000 and for the poorest 10% is $10,000. In Country B, the average income for the richest 10% is $50,000 and for the poorest 10% is $5,000. Based solely on this information, which of the following statements is the most accurate conclusion?

True or False: A decrease in a country's rich/poor ratio, which compares the average income of the richest 10% to the poorest 10%, definitively indicates that the economic well-being of the poorest 10% has improved.

Evaluating a Policy Metric
