Figure 1.5: Visualizing Within-Country and Between-Country Income Distribution (1980 vs. 2020)
Figure 1.5 offers a more advanced visualization of global income compared to charts showing only national averages, such as Figure 1.4. By using a three-dimensional format, it simultaneously displays income distribution within countries and between them. Furthermore, it presents this data for both 1980 and 2020, allowing for an analysis of how global inequality has evolved over four decades.

World Income Distribution in 2000
A chart visualizes income distribution for various countries. Each country is represented by a set of ten bars, with the height of each bar showing the average income for a 10% segment (decile) of its population, from the poorest decile in the front to the richest in the back. The countries themselves are arranged horizontally from left to right by increasing overall average income.
Consider two countries, Country A and Country B. Country A is located to the right of Country B on the chart. The bars for Country A show a dramatic increase in height from front to back, with the rearmost bar being exceptionally tall compared to the frontmost bar. The bars for Country B are all of a more similar, moderate height.
Which statement provides the most accurate analysis of these two countries based only on this information?
Analyzing Between-Country vs. Within-Country Inequality
Interpreting a Country's Income Distribution Profile
A chart visualizes global income by arranging countries from poorest to richest (left to right) and showing income distribution within each country using ten bars (deciles), from the poorest 10% (front) to the richest 10% (back). The height of each bar represents the average income for that decile. Match each country's economic description to its likely appearance on the chart.
Evaluating a Visualization of Global Income Distribution
A specific type of chart visualizes income distribution by arranging countries from poorest to richest and showing the average income for ten population groups (deciles) within each country. A key rule for this chart is that a household's total income is assumed to be divided equally among all its members, including children.
True or False: Based on this methodology, if the bar representing the wealthiest 10% of the population in Country X is taller than the corresponding bar for Country Y, one can conclude with certainty that the average household income for the wealthiest households in Country X is also higher than in Country Y.
Analyzing the Impact of Economic Policies on Income Distribution
You are presented with a chart that visualizes global income distribution. Countries are arranged from left to right by increasing average income. For each country, a series of ten bars shows the average income for each 10% segment of the population, from the poorest in the front to the richest in the back. To determine which of two countries, Country X and Country Y, has greater within-country income inequality, you would perform a series of analytical steps. Arrange the following steps in the correct logical order to make this comparison.
A chart visualizes income distribution by arranging countries from poorest to richest and using a series of ten bars to represent the average income for each 10% segment of the population (decile) within each country. If, for a single country, the bar representing the richest 10% is exceptionally tall while the bar for the poorest 10% is very short, this large height difference is a direct visual measure of high _______________.

Limitation of Average Income in Visualizing Inequality
A chart displays all the world's countries, arranged from poorest to richest based on their average daily income in a specific year. The income is measured in international dollars to account for differences in purchasing power. In this chart, the width of the bar for each country represents its total population. By examining this method of visualization, what is the most significant limitation for understanding the full picture of global economic inequality?
Evaluating Data Representation in Global Income Comparison
Imagine a chart that visualizes global income distribution. On this chart, each country is represented by a rectangular bar, and countries are arranged along the horizontal axis from poorest to richest. The height of each bar indicates the country's average daily income, and the width of the bar represents its total population. If Country X has a bar that is very wide but not very tall, while Country Y has a bar that is very narrow but very tall, what is the most accurate conclusion you can draw?
Evaluating Methods for Global Income Comparison
A chart is designed to compare the economic well-being of different countries by arranging them from poorest to richest based on average daily income. To make the comparison valid, all incomes are converted into 'international dollars'. What would be the most significant analytical error if the chart's creator had instead used nominal market exchange rates to convert all incomes to a single currency, like the US dollar?
A researcher wants to create a visual comparison of economic well-being across all countries. The plan is to represent each country with a bar, arranged from poorest to richest. To do this correctly, several steps must be taken in a specific order. Arrange the following steps in the logical sequence a researcher should follow.
A chart visualizes global income by arranging countries from poorest to richest along a horizontal axis. The width of each country's bar represents its population, and the height represents its average daily income. The horizontal axis is scaled to show the cumulative percentage of the world's population. If a very wide bar representing a single, large country is positioned such that it crosses the 50% mark on the cumulative population axis, what is the most accurate inference?
A chart visualizes global income by representing each country as a rectangle, with countries arranged from poorest to richest. The height of each rectangle corresponds to the country's average daily income, and the width corresponds to its population. If Country A and Country B have rectangles of the exact same height, but Country A's rectangle is three times wider than Country B's, what can be concluded about the total daily income of the entire population of Country A compared to Country B?

World Income Distribution in 1980 (Figure 1.5, Top Panel)
Examine the two charts provided, which illustrate the distribution of annual income across different population segments for various countries in 1980 and 2020. Based on a comparison of the two charts, which statement most accurately analyzes the change in global income distribution over this period?
Analyzing Trends in Global Income Distribution
You are presented with two charts comparing global income distribution in 1980 and 2020. In both, countries are ranked from poorest to richest, with bars representing the average income for each tenth of the population (decile). The 1980 chart is characterized by two main 'humps,' representing a large group of poor countries and a small group of rich countries. The 2020 chart is flatter, with many countries now in the middle, but it also shows very tall 'skyscrapers' representing the income of the richest decile in the wealthiest nations.
Evaluate the following statement: The data suggests that from 1980 to 2020, income inequality between countries has generally decreased, while income inequality within many countries has increased.
Visualizing National Economic Change
The Changing Shape of Global Income Distribution
Imagine two charts representing global income distribution. The 1980 chart is often described as having a 'twin-peaked' shape, with a large group of low-income countries and a smaller group of high-income countries. The 2020 chart is flatter and more continuous, but features very tall 'skyscrapers' at the high-income end, representing the wealthiest 10% in those countries. Match each described visual feature to its most accurate economic interpretation.
Consider two visualizations of global income distribution. The 1980 visualization is often described as 'twin-peaked', reflecting a large group of low-income countries and a smaller group of high-income countries. The 2020 visualization is flatter and more continuous, indicating many countries have moved into the middle-income range, but it also features extremely tall bars ('skyscrapers') for the wealthiest 10% in many nations. Based on this comparison, which of the following conclusions is the LEAST supported by the visual evidence described?
Policy Response to Income Inequality
Interpreting the 'Flattening' of Global Income Distribution
You are analyzing two charts that show global income distribution in 1980 and 2020. The charts rank countries by GDP per capita and show the average income for ten equal-sized population groups (deciles) within each country. While these charts are powerful for showing changes in inequality, what is a significant limitation of this specific visual representation for understanding the full extent of wealth concentration?
