46% of adult American internet users post original photos or videos online that they have created, and 41% repost photos or videos on sites designed for sharing images, according to [download page] September 2012 findings from Pew Research Center’s Internet & American Life Project, conducted by Princeton Survey Research Associates International. Pew calls the first group “creators,” and the second group “curators.”

Women are slightly more likely to be creators than men (48% vs. 45%), as data from “Photos and Videos as Social Currency Online” reveals, and younger Americans are far more likely than older Americans to post their original photos and videos online. The percentage of respondents in each age group who are creators is lowest in the 65+ bracket (29%), followed by the 50-64 demo (28%). By contrast, roughly half of 30-49-year-olds do so, as do about 7 in 10 of the 18-29 group.
