Global Mortality Overview for 2025
The latest public estimates indicate that approximately 62 million people died worldwide in 2025, according to preliminary data compiled by the World Health Organization and the United Nations Department of Economic and Social Affairs World Health Organization global health estimates. This figure represents a slight increase from 2024, driven primarily by aging populations in high-income countries and persistent infectious disease burdens in low-income regions. The global crude mortality rate for 2025 is estimated at 7.7 deaths per 1,000 people, reflecting a modest upward trend over the past five years.
Demographers at the UN Population Division note that the 2025 death toll includes roughly 5.4 million deaths from cardiovascular diseases, 1.9 million from lower respiratory infections, and 1.1 million from chronic respiratory diseases. The data, drawn from civil registration systems and sample registration surveys across 190 countries, is the most comprehensive publicly available snapshot of global mortality for the year. The WHO's Global Health Estimates database provides the underlying cause-of-death statistics used in these projections.
Leading Causes of Death and Regional Breakdown
Ischemic heart disease remains the single largest cause of death in 2025, accounting for approximately 9.2 million fatalities globally, followed by stroke with 6.5 million deaths WHO mortality and global health estimates database. Chronic obstructive pulmonary disease, lower respiratory infections, and diabetes mellitus complete the top five causes. In sub-Saharan Africa, malaria, HIV/AIDS, and neonatal disorders continue to rank among the top killers, while in high-income regions, Alzheimer's disease and other dementias have risen sharply in the mortality rankings over the past decade.
The regional breakdown shows that the WHO African Region recorded the highest age-standardized mortality rate in 2025, at 10.8 deaths per 1,000 population, while the WHO European Region reported 10.2 per 1,000 WHO Global Health Estimates regional data. The South-East Asia Region accounted for the largest absolute number of deaths, with an estimated 14.3 million fatalities, driven by high rates of ischemic heart disease, chronic respiratory diseases, and neonatal conditions. The Region of the Americas saw a decline in mortality compared to 2024, partly attributable to reduced seasonal influenza severity.
Key Demographic Trends and Data Sources
Life expectancy at birth for the global population in 2025 stands at approximately 73.4 years, according to the UN World Population Prospects, with variations ranging from 61.2 years in the WHO African Region to 80.5 years in the WHO European Region United Nations World Population Prospects 2024 Revision. The number of deaths among children under five has fallen to an estimated 4.7 million, reflecting continued progress in immunization, oral rehydration therapy, and neonatal care in low-income countries. However, the pace of reduction in under-five mortality has slowed in fragile states and conflict-affected areas.
The primary data sources for 2025 mortality estimates include the WHO Global Health Estimates, the UN Inter-agency Group for Child Mortality Estimation, and national vital registration systems reported to the UN Statistics Division United Nations Statistics Division mortality database.
