Which countries are most online? Saudi Arabia beats the US and Japan

Ask people to name the most connected country on Earth and you'll hear South Korea, the United States, maybe Japan. Fast broadband, big tech companies, phones everywhere. Reasonable guesses.

The numbers say something else. When you count the share of people who actually use the internet, the top of the list belongs to the Gulf and the Nordics. The United States isn't in the top 40, and Japan is behind 35 European countries.

Guess first

Which of these countries has the highest share of people online?

What's being measured

The stat is "internet usage": the share of a country's population that used the internet in the last three months, from any device, anywhere. It comes from national surveys collected by the International Telecommunication Union and published by the World Bank. It doesn't measure speed, and it doesn't care whether you have broadband at home. One check of your phone on a bus counts.

That definition matters, because it rewards places where nearly everyone is young, urban and carrying a smartphone.

The 100% club

Seven countries report that essentially everyone is online:

• Bahrain
• Denmark
• Iceland
• Kuwait
• Qatar
• Saudi Arabia
• the United Arab Emirates

Norway, Luxembourg and Monaco follow at 99%. South Korea, the usual first guess, is close behind at 97.9%, just ahead of the Netherlands and Switzerland at 97%.

"100%" deserves a footnote. It's a survey estimate, rounded, and many surveys only cover people above a minimum age. It means you'd struggle to find an adult who hasn't been online in the last three months, not that every newborn has an email address.

The Nordic entries won't surprise anyone. They've had decades of cheap connections and digital public services. The Gulf entries are the interesting ones, and they come down to who lives there. In Qatar, the United Arab Emirates and Saudi Arabia, fewer than 3% of people are 65 or older. Qatar and Kuwait are at or near 100% urban. Large shares of residents are working-age people who moved there for jobs.

Put those together and you get a country with almost no retirees and almost no villages, where almost everyone is online. Age explains more of this list than technology does.

Why Japan sits lower

Japan is the mirror image. Its networks are excellent, and its usage figure is 87%, behind 78 other countries and territories.

The reason is the same one in reverse. About 30% of Japan's population is 65 or older, one of the highest shares anywhere. The measure counts everyone, including people in their eighties who never took to smartphones. A young, urban country can reach 100% quickly. An old one has a long tail of people who simply don't go online, however good the cables are.

France, Italy and Portugal, all with older populations, sit in the high 80s too.

The bottom of the list

At the other end, the Central African Republic is at 8%, and Uganda and South Sudan are at about 9%. Burundi, Chad, Yemen, Ethiopia and Burkina Faso are all below 20%.

The gap there is mostly about access. Mobile coverage thins out quickly beyond the cities, data is expensive next to local incomes, and charging a phone needs electricity that many homes don't have.

Now count heads instead

Percentages hide the size of a country. India's internet usage is 56%, which puts 169 countries and territories ahead of it on this ranking. But 56% of 1.42 billion people is about 795 million. That's more people online than in the United States, Indonesia and Brazil combined.

By headcount, the order looks like this:

1. China, about 1.3 billion people online
2. India, about 795 million
3. United States, about 314 million
4. Indonesia, about 206 million
5. Brazil, about 187 million

Saudi Arabia, top of the percentage list, has about 37 million people in total.

How to use this in a duel

If an internet-usage question puts a Gulf state against almost anyone, take the Gulf state. If it's an old, rich country against a young, rich one, lean young. Between two poorer countries, the more urban one usually comes out ahead.

A quick caveat before you rely on any single figure: countries run their surveys in different years, so this compares each country's latest available number, not a single year. A few points either way between two countries can be survey timing rather than a real gap.
