Chapter 18, Problem 6WIO
Summary Introduction
To determine:
The graph showing the declining population, comparison between birth rate and death rate and the age structure graph.
Introduction:
The birth rate is the number of individuals born per unit of area in a unit time period. While the death rate is the number of individuals, who have died in a given area over a certain period of time. The population increases when the rate of birth rate and immigration rate is more than the death rate and emigration

What are the key factors that led to the changes in the birth rate and death rates as a country goes through the demographic transition? Describe in order that they occurred and how they affected the rates.
Using the above graph, what is the approximate percent of the population in the US and Kenya that is under the age of 15? (number order represents US, Kenya) A24,26 B12,28 C32,62 D16,36
tell whether the curves for the different cohorts are different from one another.If so, what might have caused the differences?
In addition, did you notice any difference in the curves for males and females? If so, what might havecaused the differences?Speculate about the future if: 1) health care costs continues to increase, and 2) medical advances continueand most diseases and infant mortality are eliminated.How can this method be used to understand or manage natural populations?

- Two stable populations employ the same fertility schedule, but different mortality schedule. In both populations, 20% of women between exact ages 45-55 bear a female child annually. No child bearing occurs outside this span. In population A, there is no mortality until age 100 where all who reached age perish. In population B, 1% of each cohort dies within each single year of age with no survivors beyond age 100. Compute GRR, GRR and r for each population. ii) Determine the birth and death rate of each. Sketch the age distribution of each.arrow_forwardAnswer the following questions: Why do we usually express crude birth and death rates per thousand people? Why not give the numbers per person or for the entire population. Some demographers claim that the total world population has already begun to slow, while others dispute this claim. How would you recognize a true demographic transition as opposed in mere random fluctuations in birth and death rates?arrow_forwardIf the population of 150 squirrels at UofL has 15 births this year, what is the per capita birth rate? - 0.1 squirrels/yr/squirrel If the population of 150 squirrels at UofL has 10 deaths this year, what is per capita death rate? - 0.067 squirrels/yr/squirrel Calculate the intrinsic rate of increase for this squirrel population, using your answers to the questions above. - 0.03 squirrels/yr/squirrel Between having plenty of shelter in the trees and scavenging through the campus garbage, UofL squirrels have seemingly unlimited resources. Using the information you've calculated so far, determine the growth increment for the coming year for the UofL squirrel population. - 4.5 squirrels/yr Let's say that, after you calculated your predictions for unlimited growth of the UofL squirrel populations in the questions above, a bad storm comes through campus and wipes out half the trees! Now, the growth of the population of squirrels becomes limited. There are still 150 squirrels, but the…arrow_forward

- Alyce is studying populations and how they grow. She has a population of goldfish that she's been observing. Alyse hypothesizes that the birth rate and death rate are related to the growth rate of the population. Is she correct? Choose the best answer. O a. Yes, the growth rate is equal to the birth rate minus the death rate O b. No, the birth rate and death rate are completely separate from growth rate O c. Yes, the birth rate plus death rate is equal to the growth rate O d. No, the growth rate is equal to only birth ratearrow_forwardSome demographers claim that the total world population has already begun to slow, while others dispute this claim.

- Review the age structure graphs shown in Figure 5-15. How do patterns in the graphs indicate the rate that a population is increasing or decreasing?arrow_forwardBrown fur helps unicorns blend into their environment better than white fur. Therefore, brown furred unicorns are more likely to survive predators and hunters compared to white furred unicorns. If fur colour is a heritable trait, how would the population change over time? Describe how the proportion of individuals with brown versus white fur would change over time, if at all. What process is occurring in the population?arrow_forwardThis graph plots the difference between birth rates and death rates in Mexico during the 20th century.
