The CROss-National Online Survey (CRONOS) panel is the first cross-national probability-based online panel following a harmonised approach throughout—from the recruitment stage to data processing.
CRONOS is a pilot study to evaluate the effectiveness of panel recruitment on the back of an existing cross-national survey in terms of costs, sample representativeness, participation and attrition rates, and data quality. It was designed and implemented alongside ESS Round 8 in 2016, as part of the larger SERISS project. After completing the ESS Round 8 face-to-face interview, respondents in Estonia, Great Britain, and Slovenia who were 18 or older were invited to participate in six 20-minute online surveys. Data collection took place between December 2016 and February 2018.
