Based on everything they know and have heard about the internet, only 37% of American internet and smartphone users believe it’s possible for someone to use the internet completely anonymously, so that none of their online activities can be easily traced back to them. That’s one of the takeaways from a new study [PDF] by the Pew Research Center’s Internet & American Life Project, which also finds growing concerns regarding the amount of personal data available on the internet.

Those worries appear to be well-founded: many respondents said that their photos (66%), birth dates (50%), email addresses (46%) and employer information (44%) are available online. Those numbers were significantly higher for 18-29-year-olds, among whom 90% say their photos are available online. Read the rest at MarketingCharts.
