Wikipedia usage among online American adults stands at 36% according to a Pew Internet survey in 2007. It is more popular with individuals who have higher education, such as college graduates (50% usage), young adults aged 18-29 (44%), and those with broadband connections. Usage declines with age, education level, and slower internet access, with older adults (age 50+) and dial-up users showing lower rates. Wikipedia's high traffic, placing it in the top 10 global sites, is due to its extensive content, frequent updates, internal and external linking structure that boosts search engine rankings (particularly Google), and perceived convenience compared to offline sources.
