Life expectancy rates vary all over the place depending on what sources you look at. It also depends on where you live, your life style, and more. For example, one source posted in 2009 stated:
“Life expectancy is the average number of years of life remaining at a given age. It is the average expected lifespan of an individual. Today humans have an average life span of 31.99 years in Swaziland and 82 years in Japan. Our chart shows statistics for the average age you will live based on various world countries.”
In the US, one source revealed that the life expectancy for white males born in 1900 was 47 years and for black males born the same year, it was only 33 years. There was also a disparity for women born in 1900 with white women having a life expectancy of 49 years and black women of 34 years.
Over time with huge improvements in medicine and other areas, the life expectancy numbers jumped by 1930. White males on the average lived to be 60 and black males lived to be 47. White women lived to be 64 and black women lived to be 49.
By 2000, life expectancy rates had increased to 75 years for a white male, 68 years for a black male, 80 years for a white female and 75 years for a black female.
