What share of people use the internet in each country?

The interactive chart needs JavaScript. The numbers are on the chart's page.

In 2024, 94.7% of people in the United States used the internet and 64.9% in India. The highest share was 100%, and the lowest 8.6%, in Burundi. 182 countries and territories had a 2024 figure. It counts people who used the internet at least once in the previous three months; places without a 2024 figure are left out.

How to read this chart

Each bar is the share of a country's people who used the internet in the previous three months. The dashed line is the whole world. The chart opens on the top and bottom of the ranking; search for a country to find its bar among the rest.

Questions to discuss

  1. Find the United States and one country on another continent. How far apart are their shares?
  2. What do the countries at the bottom of the ranking have in common? What might keep people there offline?
  3. The world figure is closer to the bottom than many rich countries are to the top. Why might that be?
