Total Fertility Rate - AP Environmental Science

1. What is the relationship between TFR and life expectancy?

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

2. Which region typically has the highest Total Fertility Rate?

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

3. Identify a factor that can decrease Total Fertility Rate.

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

4. How does Total Fertility Rate differ from Crude Birth Rate?

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

5. What impact does TFR have on population growth?

   Higher TFR generally leads to population growth. When TFR exceeds replacement level, population increases.

6. What type of economic incentive can reduce Total Fertility Rate?

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

7. Identify a health factor influencing Total Fertility Rate.

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

8. Which social factor can affect Total Fertility Rate?

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

9. State the effect of poverty on Total Fertility Rate.

   Higher poverty levels often correlate with higher TFR. Poor families may have more children as economic security.

10. Identify a technological factor affecting Total Fertility Rate.

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

11. What is a common consequence of a Total Fertility Rate below replacement level?

    Population decline. Fewer births than deaths leads to shrinking population.

12. Which educational factor can lower Total Fertility Rate?

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

13. Identify the effect of delayed marriage on Total Fertility Rate.

    Delayed marriage tends to lower TFR. Later marriage reduces women's reproductive years and family size.

14. Find the TFR if there are 1500 births per 750 women.

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

15. What is a direct consequence of high Total Fertility Rate?

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

16. What is the definition of Total Fertility Rate (TFR)?

    Average number of children a woman is expected to have in her lifetime. This is the standard demographic definition used globally.

17. How does access to healthcare influence Total Fertility Rate?

    Better healthcare access can reduce TFR. Healthcare reduces infant mortality, lowering need for many children.

18. Calculate the TFR given 1000 births and 500 women.

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

19. What demographic trend is associated with declining TFR?

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

20. How is Total Fertility Rate related to economic development?

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

21. What is a potential environmental impact of high TFR?

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

22. What is the primary purpose of calculating Total Fertility Rate?

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

23. What demographic factor can influence Total Fertility Rate?

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

24. Calculate the TFR for 900 births among 450 women.

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

25. What impact does female employment have on Total Fertility Rate?

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

26. What role does family planning play in Total Fertility Rate?

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

27. Identify a policy that can help reduce Total Fertility Rate.

    Government support for family planning services. Provides access to contraception and family planning education.

28. What factor can cause Total Fertility Rate to rise in a population?

    High infant mortality rates. Parents compensate for expected child deaths by having more babies.

29. What is the effect of high infant mortality on Total Fertility Rate?

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

30. How might cultural preferences for larger families affect TFR?

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

31. How does improved child survival impact Total Fertility Rate?

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

32. State the impact of government policies on Total Fertility Rate.

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

33. What is the replacement level fertility rate in most countries?

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

34. What is a social implication of low Total Fertility Rate?

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

35. How does Total Fertility Rate impact resource use?

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

36. What is the significance of a Total Fertility Rate of 2.1?

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

37. How does urbanization affect Total Fertility Rate?

    Urbanization tends to lower TFR. Urban living increases costs and reduces space for large families.

38. What is the current global average Total Fertility Rate?

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