Final answer:
The two scopes of population change are fertility and mortality rates.
Step-by-step explanation:
The two scopes of population change are fertility and mortality rates.
Fertility Rates:
Fertility rates represents the number of births per woman in a certain population or country. It is an important indicator of population growth. Higher fertility rates contribute to population increase, while lower fertility rates contribute to population decline.
Mortality Rates:
Mortality rates indicate the number of deaths per thousand people in a population. Lower mortality rates mean fewer deaths and can contribute to population growth, while higher mortality rates mean more deaths and can result in population decline.
