Total Fertility Rate - AP Environmental Science

To estimate population growth potential. TFR helps predict future population size and structure changes.

TFR tends to decrease as economic development increases. Wealthier societies invest more in education and family planning.

Sub-Saharan Africa. Region has limited access to family planning and education.

Higher levels of female education. Educated women delay marriage and pursue careers before childbearing.

Age structure of the population. Younger populations tend to have higher fertility rates.

Higher TFR can lead to increased resource demand. More children require more food, water, and energy resources.

TFR = 2.0. Basic calculation: 1500 ÷ 750 = 2.0 children per woman.

Access to maternal healthcare. Better healthcare reduces need for large families as insurance.

Family planning can lower TFR by reducing unintended pregnancies. Access to contraception allows couples to control family size.

It tends to decrease TFR. Parents need fewer children when child mortality is low.

Approximately 2.1 children per woman. Accounts for mortality and maintains stable population size.

TFR is average children per woman; Crude Birth Rate is births per 1000 people. TFR focuses on women's fertility, CBR includes entire population.

It is the replacement level fertility for most populations. This rate maintains stable population without growth or decline.

Cultural norms regarding family size. Social expectations and traditions shape family size decisions.

Approximately 2.4 children per woman. Global rate has declined from over 5 in the 1960s.

Tax benefits for smaller families. Financial rewards encourage families to have fewer children.

Policies can either increase or decrease TFR. Pro-natalist policies raise TFR; anti-natalist policies lower it.

It can increase TFR as families have more children to compensate. Parents have more children expecting some won't survive to adulthood.

Access to contraception. Birth control methods allow couples to plan and limit births.

Increased access to education for women. Education empowers women to delay childbearing and plan families.

TFR = 2.0. Simple division: 1000 births ÷ 500 women = 2.0 children per woman.

Higher life expectancy often correlates with lower TFR. Developed societies with longer lifespans have smaller families.

Increased demand for educational resources. More children require schools, teachers, and educational infrastructure.

Aging population. Fewer young people must support larger elderly populations.

TFR = 2.0. Direct calculation: 900 births ÷ 450 women = 2.0.

Increased female employment tends to lower TFR. Working women often delay or limit childbearing for careers.

They can lead to a higher TFR. Cultural values favoring large families increase birth rates.

Population aging. Low birth rates create older average population ages.

Increased environmental degradation. More people consume more resources and produce more pollution.
