Study Notes
Life Expectancy and Fertility Rate
- Sub-Saharan Africa has the lowest life expectancy
- Total fertility rate is defined as the average number of children a woman would have in her lifetime, assuming the current fertility rates remain constant
Population Dynamics Equation
- Growth rate of a population is calculated as Pt+1 = Pt + Bt - Dt + Mt, where Pt is the population at time t, Bt is the number of births, Dt is the number of deaths, and Mt is the net migration
- The factor NOT included in this equation is the growth rate of technology
Theories of Population Growth
- Developing countries refer to countries with lower economic development and higher population growth rates
- The upward shift of the income growth TP curve represents technological progress
- The authors reject Malthusian and neo-Malthusian theories due to their failure to consider the impact of technological progress on population growth
- The main determinant of population growth rates, according to the rejection of Malthusian and neo-Malthusian theories, is the level of income per capita
Microeconomic Theory of Fertility
- According to the Microeconomic Theory of Fertility, a household maximizes family satisfaction by choosing the optimal number of children based on the cost and benefits of having children
- Additional children are considered 'investment goods' because they provide a source of support for parents in old age
Criticism of Malthusian Model
- The Malthusian model is criticized for its failure to consider the impact of technological progress on land quality and production
- The model is also criticized for its assumption of a fixed land supply
Solutions to Population Growth
- Education and empowerment of women are suggested as solutions to population growth
- The subordination of women is identified as a real problem contributing to population growth
- Women's lack of economic opportunity is argued to be a primary issue driving population growth
Test your knowledge on the Neo-Malthusian theory, which suggests that poor nations will struggle to increase income per person without implementing birth control measures due to limited resources. Explore the concept of preventive and positive checks on population growth according to the theory.
