Historical Population Growth

United Nations Population Models

Measuring Population Change

Population change is measured by four basic components:

How many people are born – BIRTH RATE

How many people die – DEATH RATE How many move into an area –

IMMIGRATION RATE How many move out of a region (EXIT)

– EMIGRATION RATE

NATURAL INCREASE

NI = BIRTH RATE – DEATH RATE • Canada’s Natural Increase: 10.6 – 7.4 = 3.2 per

1000

(STABLE/CONTRACTING) Russia’s Natural Increase: 10.8 – 15.1 =

-4.3

(CONTRACTING) India’s Natural Increase: 23.0 - 8.5 = 14.5

POPULATION FACTSThe world’s population growth pattern has been exponential; it is increasing at a rapid pace that can seem uncontrollable at times.

Why the explosion in population growth?

•The number of people (death rate) is decreasing due to better medical care

•Birth rates continue to be high in COUNTRIES THAT STRUGGLE WITH POVERTY however in many newly industrializing countries like India, infant mortality is decreasing.

But Surprise!

The world’s population growth rate is decreasing on every continent. We reached our peak growth rate around 1950, and our rate of natural increase is decreasing globally.

Career Prospects Birth rates Death Rates Health Care ‘Need for Children’ – poverty Education levels Women’s Rights Infant Mortality Rate Rural living – more workers needed to collect water, etc. Sons bring wealth, dowries, etc. Sense of community

AGE THAT WOMEN HAVE THEIR FIRST CHILD IS EXTREMELY SIGNIFICANT - LONGER PROLONGED, LOWER POPULATION RATES
