When did overpopulation start?

The population explosion first occurred on a small scale and with a relatively moderate intensity in Europe and America, more or less between 1750 and 1950. From 1950 on, a much more substantial and intensive population explosion started to take place in Asia, Latin America and Africa (Fig. 2).

What are the 3 factors of population growth?

The three factors affecting population growth are birth rate, death rate, and migration. Subtracting the death rate from the birth rate calculates the natural population change, and subtracting the number of immigrants from the number of emigrants calculates net migration.
