Available data sets from the iCARE Study

In its previous incarnation (as the iCARE Study), the iCARE Platform collected data from people across the globe between 2020 and 2026.

These surveys used different methodologies, including:

  • Convenience surveys, distributed globally through a variety of methods
  • Web-panel surveys, distributed in targeted countries to obtain representative samples)
  • Longitudinal survey, known as the Canadian Longitudinal Study, or CLS

New Generation of Data Collection (2027 onward)

Now under the banner of the iCARE Platform, representative web-panel surveys will be redesigned in 2026-27 to meet new needs and the objectives of the platform. The scope of this next phase of data collection will be broadened to encapsulate attitudes, beliefs, and concerns beyond the COVID-19 pandemic to include health emergencies more generally, a term that includes pandemics, natural disasters, and armed conflicts.

These new surveys will maintain the national and international reach of previous representative (web-panel) surveys that were led in specific countries between 2020 and 2026 by the iCARE Study. Development of these new surveys will consider “hot” and “cold” phase periods (that is, active health emergency periods and non-emergency periods). Current plans foresee including surveys in Canada, Ireland, France, Colombia, Italy, Australia, and Hungary, and potentially others (such as Spain, the Netherlands, Slovenia, Japan, and Sweden). These data will also be aligned with databases from other sources and countries to support the platform’s goal to better understand both general and specific attitudes, beliefs, and concerns about health emergencies in pursuit of the platform’s overarching goal to better understand behaviours in order to help governments and populations better respond.

iCARE Study Data (2020 to 2026)

Representative Samples – Web-Panel Surveys

The iCARE Web-Panel Surveys were attempts to obtain representative samples from April 2020 to August 2026 from a series of specific countries, including Australia, Canada, Colombia, France, Ireland, Israel, Italy, the United Kingdom, and the US.

Sample size varied by country, but each sample usually included 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.

Convenience Samples

iCARE Convenience Samples are a series of cross-sectional surveys that were released approximately every six weeks from March 2020 to January 2022.

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

Canadian Longitudinal Survey (CLS)

The iCARE Canadian Longitudinal Survey (CLS) began recruitment in January 2021 and continued until August 2026. All participants who completed the iCARE Convenience Survey and indicated that they lived in Canada were invited to participate.

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