China, India language trends

comScore estimates the unique visitors to our sites from home and office users in China. Prior to August, there were too few UVs to be counted which suggests there were less than a half million. For August, comscore estimates we had 1.3 million visitors in China, for September it estimates we had 2.6 million, and for November it estimates 2.3 million. Given that comScore does not track internet usage from public locations (e.g. internet cafes), this is estimate undercounts overall activity from China. comScore estimates 1.5 million UVs visited one of the Chinese language wikipedias while 0.7 million visited the English Wikipedia.

For India, comScore estimates there were 6.3 million unique visitors to our sites. Of these, 6.1 million visited the English Wikipedia while less than 0.2 million visited one of the different Indian language wikipedias.

Presentation on Reach, Google

At the Board of Trustees meeting in San Francisco in January I walked through a short presentation on comScore with additional info on international reach and on the portion of our traffic which comes from Google. Contact me if you'd like any of the underlying data.
