where to find usage statistics?

[twtnyc]

i have a bet with a client about the percentage of americans that are wired up to the internet...

where do i find a credible source of internet usage statistics for americans?

[justgowithit]

United States Census Bureau [google.com]

As far as credible sources...... I'm out of ideas ;)

:) this has to be better than the source my client came up with....looks like an MFA page! lolol

[phranque]

about 70%.
the Pew Internet & American Life Project [pewinternet.org] tracks these things on a regular basis.

This is a very good source that gives you theInternet World Stats [internetworldstats.com]with detailed stats for each country.
