Taking America as an example, the majority of deaths are caused by chronic conditions such as heart disease, cancer, strokes, diabetes, and Alzheimer’s disease.
Since 1900 life expectancy in the United States has dramatically increased, and the principal causes of death have changed.
At the beginning of the 20th century, many Americans died young.
Most did not livepast the ageof 65, their lives often abruptly ended by one of a variety of deadly infectious diseases.
Over time, death rates dropped at all ages, most dramatically for the young.
Today, the vast majority of children born in the United States can expect to live through childhood and into their eighth decade or beyond.
About three-fourths of all deaths are among persons ages 65 and older.
