Question: Tattoos (8.2) What percent of U.S. adults have one or more tattoos? The Harris Poll conducted an online survey of 2302 adults during January 2008. According to the published report, "Respondents for this survey were selected from among those who have agreed to participate in Harris Interactive surveys."25 The pie chart at top right summarizes the responses from those who were surveyed.
