A May 2011 Pew Internet survey finds that 92% of online adults use search engines to find information on the Web, including 59% who do so on a typical day. This places search at the top of the list of most popular online activities among U.S. adults. But it is not alone at the top. Among online adults, 92% use email, with 61% using it on an average day.
Email is similar to search (and many other online activities) in that the youngest online adults, the college-educated, and those in the highest income categories are more likely than others to engage in the activity. These demographic differences are considerably more pronounced when one looks at email use on a typical day.
