New Pew report on Internet usage

Despite this growth in activity, the growth of the online population itself has slowed. There was almost no growth over the course of 2002 and there has been only a small uptick in recent months to leave the size of the online U.S. adult population at 63% of all those 18 and over. More than three-quarters of those between the ages of 12 and 17 use the Internet. The number of American adults going online grew by 47% between our March 2000 and August 2003 surveys. However, growth in Internet penetration was relatively flat over the course of 2002.
