The following question was asked to determine Americans' views on origin of human beings:

Respondents were categorized as believing in theistic evolution (option 1), evolution (option 2) and creationism (option 3) depending on their answer choice.

Forty six percent Americans believed in creationism, 32 percent believed in theistic evolution and 15 percent believed in evolution without any divine intervention. As the graph below shows, the percent of Americans who believe in creationism has increased slightly by 2 percent over the last 30 years. The percent of Americans who believe in evolution has also increased by 6 percent over the last 30 years while the percent of Americans who believe in theistic evolution has decreased by 6 percent over the same time period.

Regular church attendance is strongly positively correlated with believing in creationism, and negatively correlated with believing in theistic evolution and evolution. Among those who attend church weekly, two-thirds believe in creationism, 25 percent believe in theistic evolution and a mere 3 percent believe in evolution.

Americans who believe in creationism are more likely to be Republican than Democrat or Independent, whereas those who believe in evolution are more likely to be Democrat or Independent, than Republican. Interestingly, nearly an equal proportion of Republicans, Democrats and Independents believe in theistic evolution.
