Which stage of the DTM is the USA in?

A) stage 1

B) stage 2

C) stage 3

D) stage 4

The correct answer is D) stage 4

Stage four is defined by both low birth and death rates due to advances in the production of food, medical advances and economic prosperity which allows individuals and couples to decide when and if they want to have children. The population increases but only gradually and remains generally stable. Of course, because of immigration from countries which are in a different stage, such statistics vary according to area, social level and ethnic group among other factors.
