Washington, DC - Ipsos latest survey of Americans conducted for the American Bar Association’s International Criminal Court (ICC) Project shows that knowledge of the ICC has risen since Ipsos began tracking in 2014. The online survey of 1,004 adults also reveals that many Americans are in favor of the ICC investigating atrocities committed in Afghanistan by members of Taliban, but are split on the idea of the ICC investigating members of the US Armed Forces and the CIA for similar crimes.
About the Study
These are findings from an Ipsos poll conducted April 4-6, 2018 on behalf of the American Bar Association. For the survey, a sample of roughly 1,004 adults age 18+ from the continental U.S., Alaska and Hawaii was interviewed online in English. The sample includes 489 adults at least aware of the International Criminal Court.
The sample for this study was randomly drawn from Ipsos’s 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 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 2013 American Community Survey data. The sample drawn for this study reflects fixed sample targets on demographics. Post-hoc weights were made to the population characteristics on gender, age, race/ethnicity, region, and education.
Statistical margins of error are not applicable to online 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=1,017, DEFF=1.5, adjusted Confidence Interval=5).
The poll also has a credibility interval plus or minus 5.1 percentage points for adults who are at least aware of the International Criminal Court.
