This analysis provides a map of global wealth — with data on incomes, cost of living, and purchasing power across 110 countries.<p>The data is visualized in three ways: a geographic map, scatterplot chart, and a tool to compare countries head-to-head.<p>- Which countries have the highest and lowest incomes in the world?<p>- What is the average cost of living in my country, and how does that compare to nearby countries?<p>- If we adjust a country’s average income by the average cost of living, which countries are richer and poorer?<p>The data is sourced from WorldData.info based on the year of 2023. This has been compiled based on data from the OECD, World Bank, IMF, and Eurostat.<p>Mapping was done using the leaflet.js library, together with mapping tiles from OpenStreetMap.<p>The scatterplot chart was created using the d3.js data visualization library.
