Societal volunteering and COVID-19 mortality in high-income countries: a cross-sectional study.

This study aims to quantify the relationship between societal volunteering and the impact of COVID-19 in that society. Cross-sectional study. Data on societal volunteering were collected for 32 high-income countries (international analysis) and 50 US states (US analysis). Using regression analysis, the ability of this variable to explain COVID-19 mortality was compared with other variables put forward in the public debate (eg, vaccination rate, obesity, age). COVID-19 mortality was measured as the number of deaths due to COVID-19 per million inhabitants, from January 2020 until January 2022. Societal volunteering explains 43% (resp. 34%) of observed variation in COVID-19 mortality (R²) in the international (resp. US states) analysis. Compared with other variables, societal volunteering better explains the variation in COVID-19 mortality across countries and US states, with only the prevalence of smokers displaying a higher R² in the international analysis. Countries and states with more societal volunteering have been less impacted by COVID-19, even after accounting for differences in demographics, gross domestic product, healthcare investments and vaccination rates. Although this evidence is not causal, our findings suggest that factors beyond the public-private debate might impact the resilience of societies to a pandemic, with societal volunteering being one such factor.
