Each horizontal increment is 20 years, or a generation. It would be reasonable if deaths were increasing in proportion to births, but to be reasonable like that they would have to be assuming the population doubles every generation.
Right, the postwar population boom happened later in much of the world, but it's the same basic explanation for the projected rise in annual deaths. The number of deaths in this decade is mainly a function of what was happening 7 decades before.

That 2-3 decade upswing is the Boomers dying. Once they die it starts to plateau. The global population did in fact double from WWII to 1980
