Objective:
To analyze provisional mortality data for deaths occurring among US residents in 2025 and compare it with 2024 data.
Approach:
- Data Analysis: Researchers analyzed provisional death certificate data from the National Vital Statistics System for deaths occurring in 2025, comparing it with final mortality data from 2024.
- Statistical Methods: Age-adjusted mortality rates were calculated overall and by sex and race and ethnicity, with statistical significance assessed using z tests.
Key Findings:
- In 2025, heart disease remained the leading cause of death, accounting for 694,708 deaths, followed by cancer with 622,832 deaths and unintentional injuries with 184,265 deaths.
- The age-adjusted mortality rate was highest among Black people (869.0 per 100,000) and lowest among multiracial people (187.3 per 100,000).
Interpretation:
Provisional mortality data provide an early assessment of national mortality patterns and may guide public health decision-making.
Limitations:
- Data are provisional and may change as additional information and updated population estimates become available.
- Reporting delays may particularly affect causes of death such as unintentional injuries.
- Potential misclassification of race and Hispanic ethnicity on death certificates may impact the accuracy of mortality statistics.
- Changes in Census population estimation methods may affect comparisons, particularly for race groups with smaller populations.
Conclusion:
Provisional mortality data indicate a decrease in age-adjusted death rates in 2025.
