The Lancet has an open-access article on projected life expectancies in 35 industrialized countries by 2030. A few interesting findings are that South Korea seems to have some of the longest life expectancies and some of the largest gains in life expectancy among both sexes. South Korean women are projected to be the first to break the barrier of an average life expectancy of 90, with a 50% probability of this happening by 2030. The USA is consistently below the middle of the pack. The good news is that life expectancy is projected to increase in all countries studied, and the gap between men and women is projected to narrow. The graphics in this article are really interesting – I have picked just one below.
