Rates of the leading causes of death in high-income countries in 2021

In 2021, COVID-19 caused about 133 deaths per 100,000 population in high-income countries. This statistic displays the leading causes of death in high-income countries in 2021 by deaths per 100,000 population. Mortality from chronic diseases such as cancer and heart diseases are increasing around the world. Chronic deaths are especially prominent in Western countries, but have also recently began to increase in the developing world. 

Non-communicable disease burden

This increase in chronic and degenerative non-communicable diseases globally stems from aging populations, modernization, and rapid urbanization. Though these are all signs of socioeconomic progress, the resulting shift in disease carries a heavy burden for societies. Health expenditure makes up around 10 percent or more of the GDP in most high-income countries, and the global spending on medicines is expected to more than double from 2010 to 2027. 

Non-communicable disease risk factors and prevention

In most OECD countries, over 30 percent of adults are overweight. Lack of exercise, poor nutrition, and generally unhealthy lifestyles can often lead to a cluster of symptoms including abnormal blood levels, high blood pressure, and excess body fat, which in turn pose an increased risk of heart disease, stroke, and diabetes. However, most non-communicable diseases are preventable, and their modifiable risk factors can be lowered through lifestyle and behavioral changes.
