With 530 million users, Asia has the world's largest internet user population according to Internet World Stats.
The penetration of internet users compared to the total population however is lowest in the world with 14%, except for Africa. Given internet penetration rates in North America and Europe of 73% and 48% respectively, that bodes well for strong growth in the number of internet users in Asia for years to come, making the region important to watch in the coming years.
While China has more than double the internet users of Japan with 210 million, it has less than one fourth of Japan's internet penetration at 16%. India has third largest internet user base in Asia, almost twice as much as in South Korea, but its internet penetration is 1/13th the rate of South Korea.
