The graph is a bit complicated at first, but it will convey some interesting information if you stare at it. What jumps out at me is how many more people were dying under age 25 in 1990 than in 2016. The number of deaths in 2016 v. 1990 increased dramatically for those above 25, particularly among the older cohorts. Simply put, a lot of people are living a lot longer.
