MediaPost reports that Nielsen/NetRatings' new demographic figures for the net show an unusually high rise in high income households. Its panel-based measurements showed a 20 percent rise through 2004, reaching 10.3 million households. This high income group has consistently spent more time online, viewed more pages and spent more money on the internet than other groups. The reported rise was enough to raise eyebrows among Jupiter and comScore people as to whether the figures were consistent with reality.
