A country that has undergone a full demographic transition has?

A country that has undergone a full demographic transition typically experiences several significant changes in its population dynamics. This process reflects the shift from high rates of birth and death to low rates of both, often associated with economic development and social progress.

In the final stage of demographic transition, a country stabilizes at a lower birth rate and a lower death rate due to various factors such as improved healthcare, education, access to contraception, and shifts in societal values that emphasize smaller family sizes. This balance usually indicates a mature economy with advanced industrialization and urbanization.

Consequently, the correct answer signifies that the country not only has lower birth and death rates but also has transitioned through various stages of development—most notably industrialization. This industrialization typically leads to more job opportunities, better living standards, and improved public health, contributing to the stabilization of population growth rates.
