Percentage changes in selected causes of death in the U.S. 2000-2021
Changes in selected causes of death
There has been a decrease in the rate of death caused by many diseases, including stroked and heart disease. However, the mortality rate due to Alzheimer’s disease increased by 141 percent from 2000 to 2021. Alzheimer’s disease caused 31 deaths per 100,000 population in 2021 and is one of the leading causes of death in the United States. It was estimated that approximately 719.7 thousand people aged 65 and older in California had Alzheimer’s disease in 2020. Mortality rates due to different diseases vary by different factors, including race and ethnicity. Cancer, the leading cause of death among Asians and Pacific Islanders in the United States, accounted for 20 percent of total deaths among this population, while heart disease was the leading cause of death among the white population.
Globally, ischemic heart disease is the leading cause of death, accounting for some 16 percent of all deaths. In the early 1900's, the mortality rate was primarily concentrated among people of younger ages, but increasingly, this has shifted to older population groups. In recent years, decreased mortality rates are often linked to improved medical care, such as new developments in medical technologies. Shifts in lifestyle habits such as decreased smoking rates and healthier diets may also attribute to lower mortality rates.
