We painted this picture by taking the median household income of countries across the world and comparing that with data on the cost of a 1.5-liter bottle of water. The top chart shows the ratio of the two in terms of a heatmap, with areas where it’s expensive in pink.
Below that, we created a scatterplot, with each country resembling a dot on the graph. For the final graph, we showed the frequency – how often the median household income and water cost met, painting a clearer picture of how dire the situation is in much of the world.
