8.1 Human Populations Dynamics
Characteristics of Population
death rate
population density
birth rate
emigration rate
immigration rate
Tools for Quantifying Human Population
Doubling time
Time takes for population to double in size
70/percentage growth rate
Death Rate
Crude Death Rate
(Deaths/ Total population)x 1000
poor indicator
MEDC has higher CDR than LEDC
Infant Mortality Rate
number of deaths of children under 1 years old per 1000 live births
Fertility
General Fertility Rate
number of births per thousand woman aged between 15-49 years old
Total Fertility Rate
average births/woman of child bearing age
Birth rate
Crude Birth Rate, CBR
(Total births/total population)x1000
Age and sex structure unrecorded
Natural Increase
Trends in Population Dynamic
LEDC has a higher population growth than MEDC
less educated on birth control
need for more labour aid
women have more free time
MEDC has higher living costs
Boserup's Theory
Technocentrist view
rise in population will increase the demand for food, act as an incentive to produce more food
Limitation: Unsuitable farming practices arise
Malthusian Theory
Better food distribution as solution
But only the poor gets hungry
Population increase limited by food production
Case Study: One Child Policy (China)
Increased Stress on Resources
Deforestation
Desertification
Sewage
Fossil Fuels
Pesticide
Grazing
Demographic Transition Models
Expanding (Stage 2)
more middle age group
slightly longer life expectancy
High BR
Stationary (Stage 3)
Low DR
More old citizens
Declining BR
Expanding (Stage 1)
Rapid fall in older age group
High BR
Short life expentancy
Contracting (Stage 4)
Low DR
Long life expectancy
Low BR
