What year will humans go extinct?
If developing world demographics are assumed to become developed world demographics, and if the latter are extrapolated, some projections suggest an extinction before the year 3000. John A. Leslie estimates that if the reproduction rate drops to the German or Japanese level the extinction date will be 2400.
What will happen in 2050?
Stabilization in the population will happen in the second half of the century.
