摘要:National authorities publish COVID-19 death counts, which are extensively re-circulated and compared; but data are generally poorly sourced and documented. academics and stakeholders need tools to assess data quality and to track data-related discrepancies for comparability over time or across countries . “The Demography of COVID-19 Deaths” database aims at bridging this gap . It provides COVID-19 death counts along with associated documentation, which includes the exact data sources and points out issues of quality and coverage of the data . The database — launched in April 2020 and continuously updated — contains daily cumulative death counts attributable to COVID-19 broken down by sex and age, place and date of occurrence of the death . Data and metadata undergo quality control checks prior to online release . As of mid-December 2021, it covers 21 countries in Europe and beyond. It is open access at a bilingual (English and French) website with content intended for expert users and non-specialists (https://dc-covid.site.ined.fr/en/; fgshare: https://doi.org/10.6084/ m9.fgshare.c.5807027). Data and metadata are available for each country separately and pooled over all countries.
