Longevity, public health, medical technology The average life expectancy (LE) in 1900 was 47 years of age. In 2008, the average LE in the US was 80 years, and by 2020, the US Census Bureau projects that the average LE will be 79.5 years. Life expectancy in the US differs by sex and race. Women live about 5 years longer than men, and
whites live about 4 years longer than African-Americans. (Source:

Public health measures such as vaccinations and water treatment have added 25-30 years to our life expectancy while medical advances have added about 5 years. These measures have significantly reduced the incidence of infant mortality and allowed people to
be healthier well into their 70’s, 80’s and beyond. (Source:
