Which countries have the fastest growing populations in the 20th century?

In the twentieth century, the population grew rapidly in countries that in 1900 and most of the twentieth were agrarian with a predominantly rural population, and where child mortality and life expectancy sharply decreased due to advances in medicine. In the former USSR, these include Tajikistan, Turkmenistan, Uzbekistan and Kyrgyzstan. Partly Armenia and Azerbaijan. In Europe, Albania, where the population tripled from 1945 to 1990.

And also many Latin American countries, for example, Argentina, where there was also a migration increase, as well as African countries, for example, Ethiopia and many Asian countries (India, Turkey, Indonesia, Laos).
