Washington, DC, January 28, 2020 – A recent Ipsos poll reveals that more than six in ten Americans believe there is life on other planets. While a majority (57%) think there is intelligent life and civilizations on other planets, 26% of Americans believe that alien societies, if they exist, would be similar to human societies. Moreover, nearly half (45%) agree that UFOs exist and have visited the Earth, and more than one third (37%) say that humans will create permanent outer space colonies within the next 80 years.
About the Study
These are some of the findings of an Ipsos poll conducted between January 2-3, 2020, on behalf of Medium. For this survey, a sample of 1,005 adults age 18+ from the continental U.S., Alaska, and Hawaii was interviewed online in English.
The sample for this study was randomly drawn from Ipsos’ online panel (see link below for more info on “Access Panels and Recruitment”), partner online panel sources, and “river” sampling (see link below for more info on the Ipsos “Ampario Overview” sample method) and does not rely on a population frame in the traditional sense. Ipsos uses fixed sample targets, unique to each study, in drawing a sample. After a sample has been obtained from the Ipsos panel, Ipsos calibrates respondent characteristics to be representative of the U.S. Population using standard procedures such as raking-ratio adjustments. The source of these population targets is U.S. Census 2016 American Community Survey data. The sample drawn for this study reflects fixed sample targets on demographics. Posthoc weights were made to the population characteristics on gender, age, race/ethnicity, region, and education.
Statistical margins of error are not applicable to online non-probability polls. All sample surveys and polls may be subject to other sources of error, including, but not limited to coverage error and measurement error. Where figures do not sum to 100, this is due to the effects of rounding. The precision of Ipsos online polls is measured using a credibility interval. In this case, the poll has a credibility interval of plus or minus 3.5 percentage points for all respondents. Ipsos calculates a design effect (DEFF) for each study based on the variation of the weights, following the formula of Kish (1965). This study had a credibility interval adjusted for design effect of the following (n= 1,005, DEFF=1.5, adjusted Confidence Interval=+/- 5.0 percentage points).
