iCARE Convenience Samples are a series of cross-sectional surveys that have been released approximately every six weeks since March 2020.

In order to reach as many people around the world as possible, we use a mixture of snowball sampling and online advertising, facilitated through a vast network of over 200 international collaborators.

Convenience sampling ended on January 11, 2022.

The iCARE Web-Panel Surveys are attempts to obtain representative samples from a series of target countries, including Australia, Canada, Colombia, France, Ireland, Israel, Italy, the United Kingdom and the US.

Sample size varies by country, but each sample usually includes between 1,000 and 3,000 participants. Sample weights, according to key sociodemographic characteristics (e.g., age, sex, education), are included in most data sets to adjust analyses.

The iCARE Canadian Longitudinal Survey began recruitment in January 2021. Since then, all participants who complete the iCARE Convenience Survey and indicate that they live in Canada have been invited to participate.

Each time a new convenience sample is released, participants enrolled in the longitudinal survey are invited (by email) to complete a separate survey that allows us to track changes in participant responses over time.
