Comscore recently released some statistics on the Internet population. According to their study, the following countries have the greatest number of Internet users:
1. China: 179.7 million
2. United States: 163.3 million
3. Japan: 60.0 million
4. Germany: 37.0 million
5. United Kingdom: 36.7 million
6. France: 34.0 million
7. India: 32.1 million
8. Russia: 29.0 million
9. Brazil: 27.7 million
10. South Korea: 27.3 million
Worldwide, the total current Internet population breaks down by region of the world (by number and percentage of total):
Asia Pacific: 416 million (41.3%)
Europe: 283 million (28.0%)
North America: 185 million (18.4%)
Latin America: 75 million (7.4%)
Middle East & Africa: 49 million (4.8%)
Despite these numbers, its important to note that the number of Internet users is still only about 20% of the world's population. Asia, although well in the lead, also has the greatest growth potential. China and India each have over a billion people that aren't in cyberspace so there's still much room for growth.
