The question is asking us, if a country’s total fertility rate (TFR) is measured at 1, what does this number most likely indicate about the country’s population? A total fertility rate is the number of children born per woman, and since there are about as many women as men, each woman should have 2 children to replace the population If the number is smaller than 2, then the population will be decreasing. The correct answer ist: A. The country’s population is aging because while a population size decreases, less young people are born and more elderly people remain (from the time when the birth rate was higher)
