This cross-sectional study estimates global mortality trends post-COVID-19, indicating limited mortality displacement in populations.

The study aims to estimate all-cause mortality trends globally during and after the COVID-19 pandemic, focusing on mortality displacement.
Retrospective cross-national, cross-sectional time-series analysis of mortality data from 2015 to 2024.
Assessment of countries with high-quality national mortality reporting from the Human Mortality Database.
Comparison of actual versus expected mortality using an overdispersed Poisson regression model.
Statistically significant mortality displacement was detected in 3 of 34 countries, particularly among the elderly.
In 2024, the U.S. returned to its prepandemic mortality pattern, while most European countries did not.
Excess mortality rates in European countries indicated ongoing impacts, with Lithuania showing the highest rates.

Chen et al. (2026) studied this question.
