This might help your requirement: http://www.internetworldstats.com/ for instance, the Americas stats page: http://www.internetworldstats.com/stats2.htm offers numbers for internet population instead of percentage. But of course, there is no age or location stratification.

Every source I see show the percentage of each group that uses the Internet (e.g. 98% of those 18-29). I am looking for statistics that indicate of the total Internet population, what percentage use the Internet (e.g. of the Internet population, what percentage is 18-29 so that, in this case, age figures would add up to 100%). I wonder because we always compare our samples to Census figures when the proper comparison should be the Internet population. _______________________________________________ The Air-L@listserv.aoir.org mailing list is provided by the Association of Internet Researchers http://aoir.org Subscribe, change options or unsubscribe at: http://listserv.aoir.org/listinfo.cgi/air-l-aoir.org Join the Association of Internet Researchers: http://www.aoir.org/
