Examine the leading causes of death in the United States and worldwide
The United States
In 1900, the most common causes of death were infectious diseases, which brought death quickly. Due to advances in healthcare and medicine over the years, this has changed, alongside an increase in average life expectancy. According to national data, chronic diseases, or those in which a slow and steady decline causes health deterioration, were the most common causes of death in the United States in 2016
[1]
In addition, accidents were more common than in previous years, often resulting in quick or unexpected death. How might this impact the way we think of death, the way we grieve, and the amount of control a person has over his or her own dying process, in comparison to the infectious diseases that were prevalent in 1900?
The 15 leading causes of death and number of deaths per category in 2016 in the United States are listed below.

continue to be related to physical illnesses. Many are linked at least in part to lifestyle choices, including diet, exercise, and substance abuse. Similarly, many are preventable, to some extent, and some are avoidable if the proper actions are taken. Although these causes of death remain the same as they were in 2004, the order has changed for several of them by 2016. For example, accidents and unintentional injuries shifted from #5 in 2004 to #3 in 2016. Alzheimer’s disease became slightly more common, moving from #7 to #6, as did suicide, moving from #11 to #10. In contrast, strokes became slightly less common, moving from #3 to #5, along with diabetes, which moved from #6 to #7. Septicemia (blood disease) followed a similar trend, shifting from #10 to #11. These changes are likely attributable to a variety of factors, including lifestyle choices, social pressures and norms, and changes in responsibilities and obligations.
Deadliest Diseases Worldwide
The top 10 deadliest diseases in the world from 2015 are listed below, along with the percentage of deaths for which they were accountable. These reflect disease-related deaths only, and do not reflect deaths due to violence or suicide.
[3]
Notice there are several similarities between these and the top 15 causes of death in the United States described above.
Heart disease – 15.5%
Stroke – 11.1%
Lower respiratory infections – 5.7%
Chronic obstructive pulmonary disease – 5.6%
Trachea, bronchus, and lung cancers – 3%
Diabetes – 2.8%
Alzheimer’s disease and other dementia – 2.7%
Dehydration due to diarrheal diseases – 2.5%
Tuberculosis – 2.4%
Cirrhosis – 2.1%
Similar to the top 15 general causes of death listed above, these remained fairly consistent over the years, despite increases and decreases in each. Deaths caused by heart disease, for example, increased from 2000 by 2.8 million, and deaths caused by stroke increased by .5 million.
[4]
Lung disorders and cancers also rose by .5 million deaths, while diabetes rose by .6 million. Alzheimer’s disease and other forms of dementia also accounted for an additional .3 million deaths. Decreases were seen in lower respiratory infections, which decreased by .2 million, as well as dehydration due to diarrheal diseases, which decreased by .8 million. Furthermore, tuberculosis deaths decreased by 1 million, and cirrhosis deaths decreased by .2 million.
While the top 15 causes of death presented previously were only for the United States, these top 10 deadliest diseases are for the entire world, including both developed and undeveloped nations. Differences in various factors including but not limited to economic status, access to medical care, belief systems, and natural resources play a major role in many of these causes of death, and tend to vary substantially between countries. This presents challenges for the interpretation of this list, making it difficult to determine the true prevalence of each in specific locations.
WAtch it
Watch this video to learn about another way to measure and compare life expectancies, known as years of life lost, which measures how many years short of the life expectancy people die. Looking at
this
these
data reveals some of the leading causes of death across the globe.
The major causes of death vary significantly among age groups. As you can see in Figure 1, congenital diseases and accidents are major causes of death among children, then accidents and suicides are the leading causes of death between ages 10 and 24. This changes again in
to
middle and late-adulthood, as heart disease and cancer combined cause over 50% of deaths for those aged between 45 and 65.
Notice that unintentional injuries are the leading cause of death for the widest variety of ages, and recall from the previous section above that accidents were also found to have become increasingly common as causes of death within the United States population between 2000 and 2016.
[5]
These were the top causes of death for various age groups in the United States in the year 2016:
< 1 year – Congenital anomalies
1 – 4 years – Unintentional Injury
5 – 9 years – Unintentional Injury
10 – 14 years – Unintentional Injury
15 – 24 years – Unintentional Injury
25 – 34 years – Unintentional Injury
35 – 44 years – Unintentional Injury
45 – 54 years – Malignant Neoplasms (cancer)
55 – 64 years – Malignant Neoplasms (cancer)
65 + – Heart Disease
The causes of death on this list resemble the causes presented in the previous sections, but the breakdown of these causes by age group highlights the true prevalence of each. Unintentional injury (accidents), for example, was found to be the third most common cause of death within the United States population, but it becomes apparent from this list that it is the most common for the widest range of age groups or developmental stages.
[6]
Heart disease was found to
the
be the most common cause of death overall, but this list shows that it is more restricted to one age group (65+) than other causes. Similarly, cancer was found to be the second most common cause of death within the United States population, but this list reveals that it is most prevalent for individuals in middle to late adulthood.
Death and The Media
Interestingly, the things that actually result in death are not often the things we hear about on the news.
[7]
Because of the availability heuristic—a cognitive shortcut in which people rely heavily on information that is most readily available in their mind, people may erroneously be more afraid of sensational deaths than death by more normal causes, such as heart disease.
