Global Mortality in 2004
A snapshot of death rates, leading causes, and country rankings for 2004.
| # | Country | Death Rate | #1 Cause | Region |

HIV/AIDS-related mortality peaked globally at approximately 1.9 million deaths in 2004, with southern Africa experiencing catastrophic population-level impacts. The Indian Ocean tsunami on 26 December killed over 230,000 people across 14 countries, representing one of the deadliest natural disasters in recorded history. Antiretroviral treatment programmes began scaling up in sub-Saharan Africa, though coverage remained below 10% of those in need.
In 2004, data from 221 countries reveals the leading causes of death by share: cardiovascular diseases (29.6%), cancers (neoplasms) (14.8%), lower respiratory infections (5.4%), HIV/AIDS (4.5%), neonatal disorders (4.3%). These averages reflect the cross-country mean share of total deaths and highlight the dominant mortality patterns of the era.
Compared to 2000, the most significant shifts in the global mortality profile by 2004 include: cancers (neoplasms) increased by 0.6 percentage points (from 14.1% to 14.8%); diarrheal diseases decreased by 0.4 percentage points (from 3.3% to 2.9%); enteric infections decreased by 0.4 percentage points (from 3.7% to 3.3%); HIV/AIDS increased by 0.4 percentage points (from 4.2% to 4.5%). 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.
