According to the Pew Internet project (
www.pewinternet.org), 69
million americans go online each day which represents 54% of the
Americans with internet access. Further, they estimate that 31% of the
Americans with Internet access access search engines, 23% surf the web
for fun and 14% IM.
These figures are based on several different surveys conducted from
March through December 2003. I would suggest that you download their
data sets to test your theories. You can access their data here:
