Which of the following demographic concepts is concerned with the potential for population growth?

The fertility rate is a key demographic concept concerned with the potential for population growth. It refers to the average number of children that a woman is expected to have during her reproductive years. A high fertility rate typically indicates a potential for faster population growth, as it suggests that more individuals will be born into the population. This concept is crucial for understanding how populations change over time and the implications for resources, economies, and social structures.

In contrast, age structure provides insights into the distribution of various age groups within a population, which can influence growth rates but does not directly measure potential for future growth. Survivorship focuses on the probability of individuals surviving at different ages, which plays a role in population dynamics but does not capture the birth aspect involved in growth potential. Migration patterns refer to the movement of people in and out of areas, which can affect population size but does not directly reflect the innate growth potential signified by fertility rates. Thus, the fertility rate stands out as the central measure of potential population growth among these demographic concepts.
