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.
