Sampling and data collection
This report relies on data collected through Morning Consult’s proprietary survey research capabilities. Data comes from monthly surveys conducted among representative samples of roughly 1,000 adults per country, with unweighted margins of error of +/-3 percentage points. All interviews are conducted online. Surveys field during the second half of the indicated month.
Data is weighted to approximate representative samples of adults in each country surveyed. Weighting parameters vary by country.
