Top Causes of Death in the United States: Heart Disease, Cancer, and More
For nearly two decades, the leading causes of death in the United States have remained largely consistent. The top causes are responsible for the vast majority of deaths each year, with some variation in their order and specific rankings over time.
Heart Disease and Cancer: The Leading Killers
Heart disease and malignant neoplasms (cancer) have consistently been the two leading causes of death, accounting for a significant portion of all deaths in the country. These two causes alone have topped the list from 2000 through 2019, reflecting their major impact on public health Anderson2002Heron2015Anderson2003+7 MORE.
Other Major Causes: Accidents, Respiratory Diseases, and Stroke
Following heart disease and cancer, other major causes include:
- Accidents (unintentional injuries)
- Chronic lower respiratory diseases (such as COPD)
- Cerebrovascular diseases (stroke)
- Alzheimer’s disease
- Diabetes mellitus
- Influenza and pneumonia
- Nephritis, nephrotic syndrome, and nephrosis (kidney diseases)
- Intentional self-harm (suicide) Heron2015Heron2021Heron2019+4 MORE
These causes together account for about 74–80% of all deaths in the United States, depending on the year Anderson2002Heron2015Anderson2003+5 MORE.
Shifts in Rankings and Emerging Trends
While the top causes have remained stable, there have been some changes in their order. For example, accidents (unintentional injuries) have moved up in rank in recent years, surpassing chronic lower respiratory diseases in some years Heron2021Heron2019Heron2021. Suicide (intentional self-harm) has also entered the top 10 in more recent years, reflecting growing concerns about mental health Heron2015Heron2021Heron2019+4 MORE.
Differences by Age, Sex, Race, and Ethnicity
The leading causes of death can vary significantly by demographic factors. For example, certain causes are more prominent in specific age groups, sexes, races, and among Hispanic and non-Hispanic populations. These differences highlight the importance of targeted public health interventions Anderson2002Heron2015Anderson2003+6 MORE.
Leading Causes of Infant Death
For infants, the leading causes of death are different from those in the general population. The most common causes include:
- Congenital malformations, deformations, and chromosomal abnormalities
- Disorders related to short gestation and low birth weight
- Sudden infant death syndrome (SIDS)
- Complications related to pregnancy, placenta, cord, and membranes
- Accidents (unintentional injuries)
- Bacterial sepsis of newborn
- Respiratory distress of newborn Anderson2002Heron2015Anderson2003+6 MORE
There are also important differences between neonatal (first 28 days) and postneonatal (29 days to 1 year) periods Anderson2002Heron2015Anderson2003+6 MORE.
Conclusion
The leading causes of death in the United States have remained largely unchanged over the past two decades, with heart disease and cancer consistently at the top. Other major causes include accidents, chronic respiratory diseases, stroke, Alzheimer’s disease, diabetes, and kidney diseases. These causes account for the vast majority of deaths, though their impact varies by age, sex, race, and ethnicity. For infants, congenital conditions and complications of pregnancy and birth are the most common causes. Understanding these patterns is crucial for guiding public health efforts and reducing preventable deaths.
