Chapter 16, Problem 8SA
Summary Introduction
To analyze:
The reason why it is useful for society to know the number of 10-, 30- and 80-year-olds, in a population.
Introduction:
There could be different number of individuals in different age groups. Individuals in each age group will have different physical capabilities and needs.

[itemB5] (refer to the photo below) Which has a longer life expectancy - fish or oysters?
What is the average age of an individual in this population?
If 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…

- “Calculate the rates specified below (a to c), using the following information about the black population of the United States in 2000 (numbers were modified to simplify calculations) “( be careful to use the correct denominator) Average population size 28 million, including 7.2 million women aged 15-44. There were 13 million men in this population. Live births: 600,000 Fetal deaths: 4380 Death in the first week of life: 6120 Death in the first 28 days of life (excluded first week): 960 Death in the first year of life (excluding in the first 28 days): 3900 Total deaths in the population: 230,000 Deaths from heart diseases: 75,000, of those 45,000 occurred among men aged 35 years and above What is the fetal mortality rate?

- 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.
