Résumé

Estimates of excess deaths have been widely used to measure the overall impact of the COVID-19 pandemic on mortality. We investigate the validity of a new method—the later/earlier method—developed for forecasting the number of deaths one would expect if no shock occurs. We apply this method to estimate excess mortality during the first COVID-19 wave in France and Spain, stratified by age, sex, and region. Although both countries reported similar numbers of confirmed COVID-19 deaths, Spain recorded a higher excess death risk. The results confirm differences in COVID-19 vulnerability for population subgroups and spatial areas: adults aged 75–85 were the hardest hit; Île-de-France in France and Comunidad de Madrid in Spain registered the highest excess mortality. Applicable to other demographic phenomena, the later/earlier method is simple, requires fewer assumptions than other forecasting methods, and is less biased and more accurate than the 5-year average method.
