> The samples in Argentina, Australia, Belgium, Canada, France, Germany, Great Britain, Hungary, Italy, Japan, the Netherlands, Poland, the Republic of Korea, Spain, Sweden, and the United States can be taken as representative of these countries' general adult population under the age of 75.
> Due to the fact that the vast majority of the data was collected via Ipsos' online panels (India being the only exception, in which 1,800 were interviewed face-to-face and 400 were interviewed online), participation tends to consist of those who have access to the necessary technology. The samples in Brazil, Chile, Colombia, Indonesia, Ireland, Malaysia, Mexico, Morocco, Nigeria, Peru, Singapore, South Africa, Thailand, Turkey and Uganda are more urban, more educated and/or more affluent than the general population. While not nationally representative, the survey results for these countries provide a useful and unique indication of the direction of public opinion.
