I'm given to understand that in 670 the Isle of Wight was one of the last places in England to remain pagan (Norse pagan ...I think?). How meny people (roughly) would have actually lived there in that time?

How many people does the DoomsDay Book record being there? Is there any reason to think it Would have been drastically different 400 years earlier?

In Book IV of the Ecclesiastical History, Bede gives the population and extent of the Isle of Wight at the time Cædwalla's conquest as consisting of 1200 hida (hides), which is to say 1200 familial allotments of land. Now, the relationship of hides to units of population is inexact, but especially at the early date concerned, in the remote location in question, it offers a fairly credible general idea of how many families might have dwelt on the island.
