Question

The hypothetical island country of Gilder lies in the Mediterranean Sea off the coast of France. Demographers have studied Gilder for the past 50 years. At the beginning of the study, Gilder had a population of 20 million. The demographers have measured birth and death numbers, as well as immigration and emigration numbers, as shown in the data table. From the data, Calculate the population of Gilder for each 10-year period by filling in the Population (NO) and Population (Nt) columns in the data table. Use this formula to do your calculations: Population size: Nt = No + (B + I) – (D + E)initial population = 20,000,000

Answer 1

Answer:

Year 10 - No = 20,000,000 : Nt = 20,820,000

Year 20 - No = 20,820,000 : Nt = 22,000,000

Year 30 - No = 22,000,000 : Nt = 23,735,000

Year 40 - No = 23,735,000 : Nt = 25,843,000

Year 50 - No = 25,843,000 : Nt = 28,183,000

Answer 2

Answer:

2c) The most reasonable explanation for Gilder’s increase in population is Choice C: prosperous economy along with improved health care. The improved economy would explain the increased immigration and decreased emigration rates—that is, people would want to come to Gilder and do not want to leave, perhaps for job opportunities. A prosperous economy would lead to improved health care, which could explain the increased birth rates and decreased death rates.
