Global Mortality in 2023
A snapshot of death rates, leading causes, and country rankings for 2023.

The WHO declared the end of COVID-19 as a public health emergency of international concern in May 2023, though the virus continued to cause significant mortality, particularly among elderly and immunocompromised populations. The focus shifted to pandemic recovery: reversing disruptions to routine immunisation, TB and HIV programmes, and addressing the long-term mental health and economic consequences. Conflict-related mortality surged with escalation in Sudan, the Israel-Gaza conflict, and continued violence in Myanmar and the Sahel.
In 2023, data from 210 countries reveals the leading causes of death by share: cardiovascular diseases (30.0%), cancers (neoplasms) (17.5%), lower respiratory infections (5.0%), diabetes (4.3%), digestive diseases (4.3%). These averages reflect the cross-country mean share of total deaths and highlight the dominant mortality patterns of the era.
Compared to 2020, the most significant shifts in the global mortality profile by 2023 include: COVID-19 decreased by 8.2 percentage points (from 9.4% to 1.2%); cardiovascular diseases increased by 2.6 percentage points (from 27.4% to 30.0%); cancers (neoplasms) increased by 1.8 percentage points (from 15.7% to 17.5%); lower respiratory infections increased by 0.6 percentage points (from 4.4% to 5.0%). These changes reflect evolving risk factor exposures, demographic transitions, medical advances, and public health interventions across the world.
Global mortality statistics are compiled from multiple sources. High-income countries typically rely on national vital registration systems with medical certification of cause of death, while many low- and middle-income countries supplement incomplete civil registration with verbal autopsy surveys and hospital records. The Institute for Health Metrics and Evaluation (IHME) integrates these inputs using statistical modeling to produce comparable estimates across countries and years. The 'share of deaths' metric shown in the charts represents the proportion of all deaths in a given country-year attributed to each cause category, summing to approximately 100% across all causes. When comparing across years, small shifts of one to two percentage points may reflect updates in data sources, changes in diagnostic coding (such as ICD revision transitions), or improvements in modeling methodology rather than true epidemiological changes. Larger shifts — particularly those sustained over multiple consecutive years — are more likely to represent genuine trends in population health.
