The number of adults with internet access at home, in the office, at school or at other locations is continuing to grow at a steady rate, new research has reported.
In the past year, the number of online users in the US has reached an estimated 172 million people, a five per cent increase on last year, according to the latest estimates from Harris Interactive.
The research group found that 77 per cent of US adults are now online, up from 74 per cent in February-April 2005, 66 per cent in the spring of 2002, 64 per cent in 2001 and 57 per cent in spring of 2000.
When Harris Interactive first began to track internet use in 1995, only nine per cent of adults reported that they went online, the company said.
The proportion of adults who are now online at home has risen to 70 per cent, up from 66 per cent in 2005 and 55 per cent in the spring of 2002.
The percentage of those online at work has not really changed at around 35 per cent since last year, but is still up from 30 per cent in the spring of 2002.
Adults who are online at a location other than their home or work also remains steady at 22 per cent, up slightly from last year and compared to 19 per cent in the spring of 2002.
As internet penetration rises, the demographic profile of internet users continues to look more like that of the nation as a whole, Harris said. It is still true that more young than older people, and more affluent than low-income people, are online.
However, eight per cent of those online are now aged 65 or over, compared to 16 per cent of all adults who are 65 or over.
Some 39 per cent of those online did not go to college, compared to 47 per cent of all adults, and 14 per cent have incomes of less than $25,000, compared to 19 per cent of all adults.
