What is the term for the growth of a population when births exceed deaths?

The correct term for the growth of a population that occurs when the number of births surpasses the number of deaths is referred to as natural increase. This concept is fundamental in demography and reflects the dynamic changes in population size over time.

Natural increase signifies that a population is growing, usually indicating favorable conditions for reproduction and survival within a specific area. This growth can be influenced by various factors, such as healthcare advancements, nutrition improvements, and social conditions that support family growth.

Population density, on the other hand, refers to the number of individuals living per unit area, which does not directly relate to the dynamics of birth and death rates. Poverty typically refers to a socioeconomic condition and its effects rather than changes in population size. Primary industries are those related to the extraction and production of raw materials, which do not pertain to demographic trends or population growth metrics.

Thus, natural increase is specifically focused on the balance of births and deaths in evaluating how a population evolves over time.
