this press release by Eduventures. Eduventures is still one of the best resources on online academic education in the US, and the industry figures are worth a careful reading.
The fact that many students study online at an institution that is in their geographical proximity is not a surprise (for example my post here), but it is very interesting. On the one hand it points to the fact that online is simply a preferred alternative for some students. On the other hand, it might be an example of conservatism, and of the fact that students are not yet using online education as a tool to meet and study with people who are from distant regions, as well as from abroad.
