Life Expectancy

Back in the year 1900, the average life span for a U.S. citizen was around 47 years. Fast forward to 2019 and the average life expectancy is about 78 years. While the life expectancy for a population experiences ups and downs, in general, the average life span has been on the increase. With good medical care, proper nutrition, and a sound support system, you can look forward to living a long and healthy life, even into your 100s.

11. Initial Increases in Life Expectancy


One reason that life expectancy is higher now than it was in the 1900s is due to a decrease in infant mortality. Advancements in medicine and access to medical care mean that infants have a reduced risk of death due to disease or illness. With adequate prenatal care, the availability of antibiotics, and improved sanitation, the majority of babies are able to make it to adulthood. This means that in more recent years, attention has been focused on treating the chronic diseases and disorders of adulthood.

10. Danish Life Expectancy Study

Life Expectancy Study

A study by the University of Southern Denmark in collaboration with the Danish Aging Research Center compared the centenarian populations of Denmark and Sweden. This study gives a glimpse into factors that may contribute to longevity and a longer life expectancy. According to the Danish study, Swedish life expectancy has recently begun dwindling for the aged. Meanwhile, Denmark has experienced a drop in the mortality rate for the elderly. It appears that factors that influence life expectancy for the aging are related to their care in their later years.
