Which term is the difference between the number of births and deaths in a population?

• A. Population
• B. Expansive
• C. Natural Increase Rate
• D. Population Distribution

Answer: (C)

The change in a population from births minus deaths is a measure of growth from natural factors. When that difference is expressed as a rate (usually per 1,000 people per year), it’s called the natural increase rate. This focuses only on what happens from births and deaths and leaves out people moving in or out (migration). So the term that best matches “the difference between the number of births and deaths” is natural increase rate. The other terms describe the size of the population, a growth type, or how people are spread, not the birth-death difference itself.
