The Asia Paific region had 484 million users in September, which represents a 22% growth from the year-ago period. China registered a 31% growth during the period under review and now has 220 million Internet users.

Hong Kong grew the least, at 5%, and now has 3.9 million internet users. This however, represents a 55% Internet penetration, as that country’s population is 7 million. In contrast, only about 3-3.5% of Indians have access to the Internet.

“Asia is not only home to the largest Internet population in the world, but it is also one of the fast-growing,” Will Hodgman, comScore (NSDQ: SCOR) executive VP for the Asia-Pacific region, said in a statement. “With most markets in the region experiencing double-digit growth, marketers and advertisers have the opportunity to capitalize on the potential of the online channel to reach and engage a surging number of people engaging in a variety of consumer activities online, including reading content, watching video, playing online games, engaging with brands, conducting financial transactions and making online purchases.”
