World Population Growth

Growth Rate Birth Rate: Births per year, per 1000 people Death Rate: Deaths per year, per 1000 people Growth Rate = (Birth Rate – Death Rate)

In the last 200 years improved medicinehas cause the Death Rate to drop drastically

Population Growth In the Developed World, Birth & Death Rates are equal

Zero Population Growth, elsewhere growing rapidly

Population Growth: Why? Growth Rate is high in Latin America, Africa, parts of Asia Traditions of large families, agricultural economies Doubling time is 25 years, compared to 300 years in the

developed world

Challenges of Population Growth: Africa

Only part of world where food production has not increased since 1950.

Warfare & Weather often damage crops Rapid population growths strains countries’ resources:

Food, Clothing, Shelter and Clean Water

Challenges of Population Growth: Worldwide

Can Food Production keep pace with Population? Some Scientists say Yes, some say No. Possibilities include new technologies in irrigation,

fertilizers, new varieties of plants

Negative Population Growth Death Rate > Birth Rate: Germany & Hungary Declining Populations lead to their own problems Not enough labor, Guest Workers, Tensions, Protests

Population Distribution Populations are not evenly distributed across the Earth

or across individual countries Only a portion of the Earth is land, and only part of the land

is actually habitable

Population Movement Over the last hundred years people have been moving

from rural areas and into cities What is the significance of this movement?
