Abstract
We study how patterns of intergenerational residence possibly influence fatalities from Covid-19. We use aggregate data on Covid-19 deaths, the share of young adults living with their parents, and a number of other statistics, for 29 European countries associated with the European Union and all US states. Controlling for population size, we find that more people died from Covid in countries or states with higher rates of intergenerational co-residence. This positive correlation persists even when controlling for date of first death, presence of lockdown, Covid tests per capita, hospital beds per capita, proportion of elderly, GDP per capita, government's political orientation, percentage urban, and rental prices. The positive association between co-residence and fatalities is led by the US.
