The latest Gallup poll on evolution
"The percentage of U.S. adults who believe that God created humans in their present form at some time within the last 10,000 years or so — the strict creationist view — has reached a new low," reports Gallup (May 22, 2017). "This is the first time since 1982 — when Gallup began asking this question using this wording — that belief in God's direct creation of man has not been the outright most-common response."
Asked "[w]hich of the following statements comes closest to your views on the origin and development of human beings," 38% of the respondents accepted "Human beings have developed over millions of years from less advanced forms of life, but God guided this process," 19% accepted "Human beings have developed over millions of years from less advanced forms of life, but God had no part in this process," and 38% accepted "God created human beings pretty much in their present form at one time within the last 10,000 years or so." Acceptance of the creationist option was associated with lower education levels, Protestantism, and weekly church attendance.
According to Gallup, the poll results are "based on telephone interviews conducted May 3-7, 2017, with a random sample of 1,011 adults, aged 18 and older, living in all 50 U.S. states and the District of Columbia"; the samples were weighted to match demographics. The maximum range of sampling error for the total sample was +/- 4%. Conveniently, Gallup provides a graph showing the results from its polls using the same question since 1982.
