Extracted text: 7. Suppose that in a country 10% of all females born die in infancy, 20% die at age 20, 15% die at age 30 and one-third die age 60. Women bear one child at age 25, one child at age 28, one child at age 32, and one child at age 35. One-half of children are girls. a. Compute the TFR and the NRR. b. Suppose that mortality is reduced so that there is no infant mortality, a third of all women die at age 20 and a third at age 30 and one-third at age 60. Compute the NRR. c. Suppose now that age-specific fertility changes, so that women have (on average) one-half child at ages 25, 28, 32, and 35. Compute the TFR and the NRR.
