Which term describes the growth rate of a population as births minus deaths?

• A. Rate of natural increase
• B. Remote sensing
• C. Renewable
• D. Quadrat

Answer: (A)

Rate of natural increase measures how a population grows due to births minus deaths. It looks at the natural changes in a population over a given time (usually a year) without considering people moving in or out. When births exceed deaths, the rate is positive, meaning the population increases naturally; when deaths exceed births, the rate is negative, meaning the population decreases. For example, if there are more births than deaths in a year, you’d add the two to get the natural increase, which can then be expressed as a rate per 1,000 people. This concept helps distinguish natural growth from other factors like migration. The other terms aren’t about births minus deaths: remote sensing is a data collection method from a distance, renewable describes energy sources that can be replenished, and quadrats are a sampling method used to estimate abundance in an area.
