... from an arbitrary starting point of 20. Why 20?
What I mean is, if you're 50, it's an increase of 200%, which you could say is even more remarkable except that it can't be as it's the same statistic?
- wjnc 8y agoBecause infancy-related deaths have clearly declined most in recent decades and excluding them by some arbitrary cut-off still is reasonable methodologically? A graph would have been better.
- MarkMc 8y agoI'm not sure why you feel that life expectancy at age 20 is the same statistic as life expectancy at age 50, but to answer your question I chose age 20 because many people seem to think that the only major improvement has been in childhood mortality. But clearly there has also been significant improvement in adult mortality - at all ages.
