Population Growth

The 4 Demographics

Pre-transition - Many people are born but many people die because medicines, hygiene, and food supplies are not very good

Early Transition - This is when the Industrial revolution started. In the stage many people are born but not as many died because medicines, hygiene, and food supplies get better more children survived, causing a population explosion

Late Transaction - Families don’t have as many kids because there is a higher chance of them surviving

Post-Transition - The natural increase rate doesn’t change because the death rate and birth rate are equal

The Future of Population

Environmental Implications

Political Implications

Population growth can strain political institutions and put pressure on some services.

The Federal Government relies on population growth to help get the federal budget into surplus

The government will have to take population growth into account when passing laws. For example, COVID 19 and the number of people that would be infected if they allowed flights to enter and leave the country.

Economic Implications

Controlling the Population

Governments can put more money in health care because with more medicine less people die and people will want to have less children

If education was more available more people will want to have a higher education and have less kids later on in their lives. More educated people also means more doctors, researchers, inventors, and entrepreneurs boosting the economy

Increasing the rate of contraception in poor countries by putting more money into it will help lower birth rates.
