In that context, a national survey of 1,520 adults conducted March 7-April 4, 2016, finds that Facebook continues to be America’s most popular social networking platform by a substantial margin: Nearly eight-in-ten online Americans 1 (79%) now use Facebook, more than double the share that uses Twitter (24%), Pinterest (31%), Instagram (32%) or LinkedIn (29%). On a total population basis (accounting for Americans who do not use the internet at all), that means that 68% of all . adults are Facebook users, while 28% use Instagram, 26% use Pinterest, 25% use LinkedIn and 21% use Twitter.
Data about how smartphone owners use their phones over the course of one week (Chapter 3) is taken from the American Trends Panel “experience sampling” survey, conducted November 10-16, 2014 among 1,635 respondents. Respondents were asked to complete two surveys per day for seven days (14 in total), using either an app they had installed on their phone (n=697) or by completing a web survey (n=938). All findings in this report are based on respondents who completed 10 or more surveys over the course of the week-long study period (n=1,035). The margin of sampling error for smartphone owners who completed 10 or more surveys is plus or minus percentage points. For more details about this survey, see Appendix C.
