The correct answer is option a. "a low birth to death ratio".
Explanation:
The birth to death ratio (BDR), is basically the mean of births in comparison to the mean of deaths in a particular region. BDR is used to track the changing relationship between fertility and mortality in a population. A value of more than 1 means that there is an increase in the number of people in a region. On the other hand, a low BDR would lead to a decrease in the population and eventually in the formation of a small population. For instance, regarding the white population in the US the BDR fell from 1.21 in 2000 to just 0.98 in 2016.
