Data and Application for Age Mortality Trajectories During Pre-COVID, COVID and Post-COVID Years 2018-2023 in 113 Countries

Abstract

New data and applications enable a more detailed study of the spectrum of diseases across the calendar years 2018–2023. The data system and application were developed primarily from the perspective of mortality dependence on age. Age trajectories of mortality (ATM) are important indicators of population health. In recent years, significant global events have impacted ATM. Earlier data and applications covered calendar years only up to 2018. However, the period from 2020 to 2023—marked by excess mortality—offers new opportunities for expanding the ATM database and its applications. Constructing ATM within individual calendar years from 2018 to 2023 represents a major methodological extension. Specifically, 2018 and 2019 serve as reference years, 2020 and 2021 correspond to the COVID-19 pandemic, and 2022 and 2023 reflect a period of relaxation. The presented data and application are expected to serve primarily as an initial exploratory tool, with their greatest value lying in enabling more detailed follow-up analyses on filtered data from specific countries.
