Population Geography

3.  Death Rate – deaths per year for every 1,000
people
 Declines due to improved healthcare, abundant
food supplies, advances in technology, better
living conditions

4.  Birthrate – birth per year for every 1,000
people
 Increases due to cultural beliefs (marriage,
family, value of children)

5.  Natural Increase = birthrate – death rate
 Negative Population Growth
 Birthrate < Death Rate
 Zero Population Growth
 Birthrate = Death Rate
 DoublingTime – # of years for pop. to double

6. INCREASING POPULATION
 Food production
 Warfare
 SevereWeather
 Shortages of limited
resources
 Water, housing,
clothing, etc.
DECLINING POPULATION
 Shrinking workforce
 Decreasing GDP
 Immigration
 Clashing cultures

7.  Population Distribution – pattern of settlement
 30% of earth is land, not all inhabitable
 People settle near fertile soil,
water, moderate climate

9.  Population Density – the average number of
people living on a square mile (kilometer) of land
=Total Population /Total Land Area
 Does not account for uneven population distribution
within a country

10.  MetropolitanArea – cities & surrounding
urbanized areas
 Urbanization – Growth of city populations
 People migrating from rural villages looking for
jobs / more opportunities
 1/2 of the world’s population live in cities
