Determinants And Implication of Population, Size And Growth - SS1 Economics Lesson Note
Determinants of population size and growth refer to the factors that affect the number of individuals in a given area or market segment, and the rate at which this number is changing. The size and growth of a population are influenced by several factors including:
-
Birth rates - the number of births per 1000 individuals in a population.
Death rates - the number of deaths per 1000 individuals in a population.
Migration - the movement of people into or out of a population.
Life expectancy - the average age a person is expected to live in a given population.
Fertility rates - the number of children born to each woman in a population.
Implications of Population Size and Growth:
The implications of population size and growth can vary depending on the context, but some common implications include:
-
Resource use and availability - a larger population can put more strain on resources such as food, water, and energy.
Economic growth and development - a growing population can lead to increased economic activity, but can also put strain on infrastructure and social services.
Environmental impact - a larger population can have a greater impact on the environment through increased pollution, deforestation, and other forms of resource use.
Social and political change - a growing population can lead to changes in social norms, political systems, and cultural practices.
Health and well-being - a larger population can put strain on healthcare systems and affect the overall health and well-being of individuals in the population.
