During phase one, the country is pre-industrial. There are high birth rates and high death rates, making the population stable. High birth rates can be from the cause of lacking in contraception, educating on preventing pregnancy, and also children who are needed in working. High death rates can be from the cause of lacking in proper medical care, bad living conditions, lack of sanitation, and also poverty. During phase two, the country is in a transitional phase. The society is beginning to industrialize, death rates are dropping quickly, but birth rates stay the same. The population growth is at the greatest point. The death rate drops because of medical care becoming more available and also living and sanitation conditions improve. During phase three, the country is now industrialized. Birth rates fall and death rates remain low as well. The birth rates fall because women and girls become more educated, there is birth control, and also jobs available. Death rates stay low because medical care and sanitation is widespread and improved. During phase four, the population stops increasing and at times declines when birth rates decrease below the death rates. It is represented by affluence and economic development.
