- 1Malthus Basic TheoryPopulation increasing faster than the production of resources
- 2Environmental Impact EquationI = (P, A, T)
I - environmental impact
P - population
A - affluence
T - technolgoy - 3Demographic Transition Model Stage 1- Living as hunter/gatheres, high reliance on agriculture, low access to education
- High birth rate and high death rate
- No population growth rate
- Prevalence of infectious disease - 4Demographic Transition Model Stage 2• Rurally expanding
• High birth rate, low death rate
• More peaceful, less war
• Population growth rate increasing - 5Demographic Transition Model Stage 3• Industrialization
• Low death rate, birth rate declines
• Population growth still expanding but leveling off
• The world as a whole is in stage 3 - 6Demographic Transition Model Stage 4• Low birth rate – oscillates
• Low death rate – death oscillates due to epidemics but is more stable
• Australia at the end of stage 4 - 7Basic Demographic EquationPt+n = Pt + (B-D) + (I-O)
Pt+n = population at time t plus n years
Pt = population at time t
B = births occurring between t and t+n
D = deaths occurring between t and t+n
I = gains from immigration
O = losses through emigration - 8Crude Birth RateCrude Birth Rate: number of births in a year per thousand population
- 9Total Fertility RateTotal Fertility Rate: the average number of children a woman will bear during her lifetime
- 10Net Reproduction RateNet Reproduction Rate: number of daughters a woman will bear who in turn survive to complete their own childbearing
- 11Replacement FertilityThe level of fertility needed for a woman to just replace herself in the next generation = NRR of 1.0 (TFR = approx. 2.1)
- 12Fertility Policies: Stop Having Babies• State-led campaigns (China)
• Non-governmental organisations (NGOs) and UN bodies
• Lack of support for parents - 13Fertility Policies: Have Babies1. Support for parents (child care, baby bonus, maternity leave)
2. Changing attitudes about the nuclear family – less stigma around the ‘typical’ family - 14Crude Death RateCrude Death Rate: numbers of deaths in a year per thousand population
- 15Infant Mortality RateInfant Mortality Rate: deaths of infants aged under one per thousand births
- 16Life ExpectancyLife Expectancy at Birth: average number of years a person can expect to live
- 17Ageing PopulationsLower fertility + longer life expectancy = ageing population
- 18Population MomentumThe increase in population due to the movement of large cohorts into older age groups - change of population over time
