C) TFRs below 2.1 mean that a country's population is decreasing and getting older. This is because a TFR (total fertility rate) of 2.1 is considered the replacement level fertility, where a population exactly replaces itself from one generation to the next, without migration. A TFR below this level means there are not enough births to replace the aging population, leading to a decrease in population size and an increase in the average age of the population.
