Factors Affecting Total Fertility Rate
Total Fertility Rate (TFR)
Average number of children a woman in a population will bear throughout her lifetime.
Higher TFR generally indicates higher birth and population growth rates.
Replacement Level Fertility
TFR required to offset deaths and maintain a stable population size.
Approximately in developed countries.
Higher in less developed countries due to higher infant mortality.
Infant Mortality Rate (IMR)
Number of deaths of children under 1 year per 1,000 people.
Higher in less developed countries due to lack of access to healthcare, clean water, and sufficient food.
Higher IMR often leads to higher TFR as families have replacement children.
Factors Affecting IMR Decline
Access to clean water.
Access to healthcare (hospitals, vaccines, vitamins, and supplements for mothers and babies).
More reliable food supply.
Development (Affluence) & TFR
More developed nations typically have lower TFRs.
Increased educational access and economic opportunities for women.
Greater access to family planning education and contraceptives.
Delayed first pregnancy.
Reduced need for children for agricultural labor.
Government Policy & TFR
Policies can influence fertility rates through coercive or noncoercive measures.
Examples include forced or voluntary sterilization, China's one (now two) child policy, tax incentives, and microcredits for women.
Affluence & TFR
Increased access to contraceptives and family planning.
Educational and economic opportunities compete with raising children.
Lower IMR contributes to lower TFR.
Female Education & TFR
More education leads to fewer unplanned pregnancies.
Increased job opportunities serve as an alternative to marrying young.
