Represents the growth of a population predicted by the logistic model
C
Which of the following best exemplifies population momentum?
Continued growth of a population after fertility drops to replacement level.

Population decreasing at greatest rate
D
Which of the following age structure diagrams represents a population that most likely has a negative growth rate?

Directions: Select the choice that best fits each statement. The following question(s) refer to the histograms below, which show age structure expressed as percentage of population for Countries I, II, and II in 1990. Countries undergoing rapid populations growth include which of the following?
I only.
Factors that affect the total fertility rate of a human population include which of the following? I. Cultural traditions II. Government policies and economic incentives III. Education level and economic opportunities for females
I, II, and III
Which of the following is a true statement about replacement-level fertility?
It is greater in countries with high infant-mortality rates than in countries with low infant-mortality rates.
Which of the following statements best describes the trends in the data shown in the graph above?
More-developed countries tend to have lower total fertility rates than less-developed countries.
What two main factors would best indicate the quality of life of a country's population?
The life expectancy and the infant mortality rate.
Which of the following is a true statement about the total fertility of a society?
The total fertility of a society decreases as the society progresses through the demographic transition.
The total fertility rate in country A was 6.8 in 1980. Which of the following statements best supports the change in the total fertility rate in country A between 1980 and 2015?
The total fertility rate decreased as a result of a delay in age of first marriage and increased contraceptive use.
Which of the following characteristics is most closely associated with a country that demonstrates the age structure in the diagram shown above?
There is a high total fertility rate.
In a human population, the population momentum effect is most likely to occur in cases in which a large percent of people in the population are in which age-group?
Younger than eighteen years old.
The world population growth rate in 2015 is about 1 percent. It is expected to drop to 0.5 percent by 2050, partly because of increased access to birth control in developing nations. Another likely cause for the expected decline is
increasing numbers of women entering the workforce in developing nations.
A country with an age distribution like that shown in the figure above, is most likely a country that
is experiencing slow or no population growth.
