In the years from 1900 to the present, life expectancy in the United States has drastically increased.
The tremendous increase in life expectancy during the last century may be the greatest human achievement.
In the 110 years between 1900 and 2010, the United States' life expectancy at birth increased from 47.3 to 78.7 years (Centers for Disease Control and Prevention/National Center for Health Statistics [CDC/NCHS], 2012, 2013). Declines in infectious diseases and fatalities disproportionately among the young caused this longer lifespan. After infectious diseases accounted for the majority of deaths, the leading causes of mortality were cancer and cardiovascular diseases. In the second half of the 20th century, these then became the focus of science and medicine.
