The leading causes of death in the United States have shifted significantly over the past 250 years, reflecting advances in medicine and public health. In 1776, common causes of death included smallpox, tuberculosis, pneumonia, and various waterborne illnesses, with an estimated life expectancy of about 30 years. Today, life expectancy has risen to nearly 80 years, with chronic conditions now dominating mortality statistics. In the early 1900s, influenza, pneumonia, and heart disease were prevalent, indicating a gradual transition in health issues. The historical context shows that the absence of antibiotics, vaccines, and modern medical practices contributed to higher fatality rates in earlier centuries.
