Missing mortality: closing the data gaps
Ce dossier présente les résultats d'une étude internationale évaluant, sur la période 1990-2023 et pour 204 pays et territoires, les causes de décès, les années de vie perdues ainsi que les années de vie ajustées sur l'incapacité
Data on who is dying, when they are dying, and what they are dying from are crucial for identifying vulnerable populations and targeting health interventions, as well as for resource planning and prioritisation. Comprehensive civil and vital registration systems (CVRS) provide data on all births and deaths, allowing countries to track levels and causes of mortality. These systems are generally considered the most reliable source of data on key demographic metrics such as life expectancy and mortality rates;1 however, in many settings, CVRS are either not fully functioning or not available at all, leaving a major data and intelligence gap. In the absence of these data systems, countries and multilateral agencies instead need to rely on smaller scale surveys,2,3 which are not necessarily representative of the population and sometimes have long gaps between surveys or rely on global modelled estimates.
