Do Americans Believe in UFOs? – Gallup Poll

Americans’ views on whether UFO sightings have involved alien spacecraft are based on a telephone poll conducted Aug. 1-14, 2019, with a random sample of 1,522 adults, aged 18 and older, living in all 50 U.S. states and the District of Columbia. For results based on the total sample of national adults, the margin of sampling error is ±3 percentage points at the 95% confidence level. The margin of sampling error includes a computed design effect for weighting.

Each sample of national adults includes a minimum quota of 70% cellphone respondents and 30% landline respondents, with additional minimum quotas by time zone within region. Landline and cellular telephone numbers are selected using random-digit-dial methods.
