Study Notes
Population Dynamics
- Population dynamics studies how a country's or region's population changes, considering factors that increase and decrease the population to determine the total growth rate.
- Three factors contribute to the total growth rate: fertility, migration, and mortality.
Fertility
- Fertility refers to the natural ability of humans to have babies, which adds to the population.
- Birth rate is measured as the number of births per 1,000 people in a year.
- Total fertility rate is the number of children a woman is predicted to give birth to in her childbearing years.
- A total fertility rate of:
- Less than 2 decreases the population.
- Exactly 2 neither adds nor subtracts from the population.
- More than 2 increases the population.
- A total fertility rate of:
Migration
- Migration looks at the number of people moving into and out of countries, which changes the population of a specific country or region.
- Immigration is the movement of people into a country, increasing the population.
- Emigration is the movement of people out of a country, decreasing the population.
- Migration rates are measured per 1,000 people in the country.
Mortality
- Mortality refers to the fact that everyone eventually dies, decreasing the population.
- Mortality rates are measured as the number of deaths per 1,000 people in a year.
- Age-specific mortality rates provide a more accurate comparison between countries.
- A life table or mortality table shows the probability of death given a person's age.
Population Growth Rate
- The population growth rate is calculated by adding the number of births and immigrations, and subtracting the number of deaths and emigrations.
- A negative growth rate occurs when the number of deaths and emigrations exceeds the number of births and immigrations.
Additional Factors
- Internal migration refers to people moving within their own country, affecting the economics or cultures of a country.
- Urbanization is often a result of internal migration, as people move from rural to urban areas.
- Surveys and records are used to estimate population changes, as it is not possible to get an exact headcount of all people in the world.
