6. Context The last Covid wave had ended and a large-scale vaccination program. This program was about to be implemented as the survey entered the field. No serious policy measures were otherwise undertaken. The third Covid wave had not produced much of excess mortality. There were no heavily restrictive measures due to Covid-19 in Sweden. Given the web- and postal based survey the pandamis was not an issue for the fiedwork. Some questions focusing on the impact of COVID-19 on finances, mental wellbeing, relations with family and friends, and work satisfaction, were asked in the survey.
