What is the current world human population growth rate? Based on current technology, what is the best estimate of the maximum population that the earth can support?
What do demographers study? Why does the death rate usually decline quickly during a demographic transition?
What happens during the pre-industrial stage 1 of the demographic transition? What happens during the post-industrial stage 4 of the demographic transition? What is life expectancy? What does an age structure diagram shaped like a pyramid indicate? China has greatly reduced their fertility rates. What method did they use? The total fertility rate is the number of children born a to the average woman per year. Ans: b Section ref: Demographics of Countries.
What are the 3 most populous countries? The natural birth rate in Canada is declining yet the population continues to grow. What makes that possible? Which of the continents shown is likely to have a higher percentage of people who are chronically ill or disabled, and these people require more health care and other social services? Improving economy in a country is generally correlated with which of the following?
Which of the following factors affects the total fertility rate for human populations today? Why are high fertility rates generally encouraged in developing countries? Ans: d Section Ref: Culture and Fertility. What are family planning services? How does increasing education result in a decrease in total fertility?
In Sri Lanka, the average age at marriage is 25, and the average number of children born per woman is 2. In Bangladesh, the average age at marriage is 17, the average number of children born per woman is 3. Which of the following conclusions is supported by these data?
In most developing nations, a higher percentage of women than men are illiterate. What might be the reason for this? Which of the following statements refers to urbanization? Ans: a Section Ref: Urbanization. To what can the young age structure of urban areas be attributed? Which of the following best describes an urban brownfield?
What is one way in which urban areas in developing nations differ from urban areas in highly developed nations? What is the impact of urban development on waterways? The city of Curitiba in Brazil is a good example of compact urban development. What percentage of its commuters use mass transit? Include comments on the incentives and penalties involved. Suggested Ans: Recognizing that its rate of population growth had to decrease or the quality of life for everyone in China would be compromised, in the Chinese government began to pursue birth control policies seriously.
It urged couples to marry later, increase spacing between children, and have fewer children. In China instigated a more aggressive plan to reduce the birth rate, announcing incentives to promote later marriages and one-child families. A couple who signed a pledge to limit themselves to a single child might be eligible for incentives like medical care and schooling for the child, cash bonuses, preferential housing, and retirement funds.
Penalties were instituted, including fines and the surrender of all of these privileges, if a second child was born. Section Ref: Chapter Opener. Explain why cockroach populations will not expand indefinitely and take over the entire world.
Include in your discussion appropriate definitions of population growth terminology such as: exponential growth, carrying capacity, and resistant factors. Suggested Ans: Cockroach populations exhibit exponential growth, which is accelerating population growth that occurs when optimal conditions allow a constant reproductive rate over a period of time.
When the cockroach population grows exponentially, the larger the population gets, the faster it grows J curve. However, environment resistance factors limit growth of the population. As the number of individuals in a population increases, so does environmental resistance, which acts to limit population growth. The population of roaches would level at the carrying capacity appropriate for the local environment.
The carrying capacity is the maximum number of individual of a given species that a particular environment can support for an indefinite period, assuming there are no changes in the environment.
