Pre-industrial Stage	Transitional Stage	Industrial Stage	Post-industrial Stage
Birth rate is high to compensate for high infant mortality rate. Less developed countries are in this stage. Women have many children and unfortunately many do not survive into adulthood.	Industrialization begins. Access to food and improved healthcare lowers death rate.	Death rate drops due to improved medicine and modernization. Mostly developed countries are in this stage.	Birth rate drops to equal zero population growth. If the birth rate falls below death rate, than population will decrease
