In 2019, the top ten causes of death accounted for 55% of the world’s 55.4 million deaths.
Why do we need to know why people are dying?
The world’s leading consecutive causes of death are linked to three major problems: cardiovascular disease (ischemic heart disease, stroke), respiratory disease (chronic obstructive pulmonary disease, lower respiratory tract infections) and neonatal trauma, including neonatal diseases – including
Causes of death can be divided into three groups: infectious diseases (infectious diseases and parasitic diseases as well as maternal, perinatal and nutritional diseases), non-communicable (chronic) and injuries.
The most common causes of death worldwide
Globally, seven of the top ten causes of death in 2019 were infectious diseases. These seven causes accounted for 44 percent of all deaths or 80 percent of the top ten. However, all non-communicable diseases accounted for 74 percent of global deaths in 2019.
The largest cause of death in the world is ischemic heart disease, which accounts for 16% of the world’s deaths. Since 2000, the number of deaths caused by the disease has increased the most, by more than 2 million to 8.9 million deaths in 2019. Stroke and chronic obstructive pulmonary disease are the second and third leading causes of death, which is approx. 11% and 6% of total mortality are responsible.
Lower respiratory tract infections were still the deadliest infectious disease in the world, ranking fourth as the leading cause of death. However, the number of deaths has fallen significantly: 2.6 million people died in 2019, 460,000 less than in 2000.
Neonatal diseases are fifth. However, neonatal deaths fall into the categories with the largest worldwide decline in deaths in absolute terms in the last two decades: 2 million newborns and young children died in 2019, 1.2 million less than in 2000.
The number of deaths caused by NCD is increasing. The number of deaths from trachea, bronchi and lung cancer has risen from 1.2 million to 1.8 million and is now the sixth leading cause of death.
In 2019, Alzheimer’s disease and other dementias were the seventh leading causes. Women suffer disproportionately. Worldwide, 65% of deaths from Alzheimer’s disease and other dementias are women.
One of the largest deaths is due to diarrhea and deaths worldwide from 2.6 million in 2000 to 1.5 million in 2019.
Diabetes has risen to the top ten causes of death, a significant increase of 70% since 2000. Diabetes is also responsible for the largest increase in deaths in the top ten men, an increase of 80% since 2000.
Other diseases that were among the top ten causes of death in 2000 are no longer on the list. HIV / AIDS is one of them. The number of HIV / AIDS deaths has fallen by 51% in the last 20 years, from the eighth leading cause of death in the world in 2000 and the ninth in 2019. Kidney disease has risen to tenth of the world’s leading cause of death. The mortality rate has risen from 813,000 in 2000 to 1.3 million in 2019.
The most common causes of death by income group
People living in the country of arrival are much more likely to die from a contagious disease than from a non-contagious disease. Despite the global recession, six of the top ten causes of death in emerging countries are infectious diseases.
Malaria, tuberculosis and HIV / AIDS all remain in the top ten. However, all three are clearly declining. Of the ten deaths in this group, HIV / AIDS decreased the most. 59% fewer deaths in 2019 than in 2000 from 161,000 and 395,000 deaths.
Diarrhea is the leading cause of death in low-wage countries: it is among the top five causes of death in this income category. However, the incidence of diarrhea is declining in low-income countries, the second largest reduction in deaths among the top ten (231,000 fewer deaths).
Deaths from chronic obstructive pulmonary disease are particularly rare in income countries compared to other income groups. It does not appear among the top ten low-income countries, but it is among the top five of all other income groups.
