Global Mortality in 2006
A snapshot of death rates, leading causes, and country rankings for 2006.

By 2006, antiretroviral therapy coverage in low- and middle-income countries had reached 28%, up from 7% just two years earlier, demonstrating that large-scale HIV treatment was feasible even in resource-limited settings. The WHO revised its air quality guidelines, highlighting that air pollution caused an estimated 2 million premature deaths annually. Avian influenza H5N1 raised pandemic fears, prompting accelerated pandemic preparedness planning.
In 2006, data from 221 countries reveals the leading causes of death by share: cardiovascular diseases (29.8%), cancers (neoplasms) (15.1%), lower respiratory infections (5.3%), digestive diseases (4.3%), neonatal disorders (4.2%). 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 2006 include: cancers (neoplasms) increased by 1.0 percentage points (from 14.1% to 15.1%); diarrheal diseases decreased by 0.5 percentage points (from 3.3% to 2.8%); enteric infections decreased by 0.5 percentage points (from 3.7% to 3.2%); neonatal disorders decreased by 0.4 percentage points (from 4.6% to 4.2%). 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.
