Two questions in Public Attitudes to Science 2011, a survey conducted by Ipsos MORI in association with the British Science Association for the United Kingdom's Department for Business, Innovation, and Skills, are relevant to the creationism/evolution controversy.
The topline report details (PDF) that, presented with "Human beings have evolved from other animals," 67% of respondents agreed and 17% disagreed, with 12% neither agreeing nor disagreeing and 3% saying that they didn't know; presented with "God created the earth and all life in it," 39% of respondents agreed and 37% disagreed, with 21% neither agreeing nor disagreeing and 3% saying that they didn't know.
The survey was conducted among 2103 British adults aged 16 or older, in face-to-face in-home interviews from October 11 to December 19, 2010; the data were weighted to reflect the population profile of the United Kingdom.
