Amanda,
contact Rich Ling from Telenor at Oslo at <richard-seyler.ling@telenor.com>. He works on that issue since a couple of years.
In our own data from EURESCOM's P903 we start with 15+ aged and compare face to face, fixed line, mobile phone, SMS, email and letter exchanges within netorks of family, of friends, and of acquaintances, for intra-agglomeration, national, and international distances. Data are from end 2000 and cover Norway, denmark, Germany, the Netherlands, UK, France, Italy, Spain, and the Czech Republic. I guess you have access to the data.

Good luck

Frank Thomas

Hello Aoir's,

I've been digging around for days looking for global data on the number/percentage of youth (any segment of ages between 9 and 24) who use the Internet/use email/use IM, and I've come up with very, very little.
Does any one know of a source for such numbers?
I'd particularly like both a global number or estimate and/or a country by country break down on use.

I'd also love a comparative look at IM versus SMS use in a variety of countries. In countries where SMS use is so prevalent among youth, is IM ever used?

thanks,

Amanda Lenhart
