According to the graph, I would like to state the three points.
To begin with, from 1800 to 2012, global, average life expectancy was increasing from 32 years to y/o years. It seems that this is because medical technology has been developing.
Secondly, the lower the cumulative share of the world population such as India the lower the life expectancy at birth. Meanwhile, the higher the cumulative share of the world population such as the USA and German the higher the life expectancy at birth. It seems that the cumulative shore of the world population and life expectancy are related.
Thirdly there are countries like South Korea, Spain, and Japan the cumulative share and life expectancy increased. It seems that this is because these countries are economically grown.
