Explain fertility rate trends. + Factors
Replacement rate: ~2-2.3
Countries like India and Japan have dropping or low fertility rates in general.
What are some factors that affect fertility rates:
-Disease (ex. COVID-19, Bubonic Plague)
- Education, Partner preference
- Environment Concern, Cultural factors,
- access to food/water, economic uncertainty
5 stages of demographic transition in a population.
1st: Lots of death + births
2nd: society stabilizes, slowing death rates
3rd: society advances, but realizes birth rate too high.
4th: population slowing down.
5th: Birth rate unsure, death still low.
What is the demographic dividend?
of working people > # of young people
ex. India
Ratio: (15-65) of individuals working vs non-working
As a result, when working generation retires, future generation will have a low count of workers.
Thomas Malthusian Model?
Population grows exponentially, food grows linearly.
Eventually population food requirements exceed food supply and require for a decrease in population growth (less food= less births)
Therefore, population growth is maintained.
The Population Bomb?
Diminishing resources = famine/catastrophe
IPAT: Impact = population x affluence x technology
