What characteristic is commonly associated with a rapidly growing population?

A characteristic commonly associated with a rapidly growing population is a high birth rate. In demographic terms, when a population experiences rapid growth, it is often due to a large number of births relative to the number of deaths. High birth rates contribute significantly to population growth as they increase the overall number of individuals in a given area.

In many cases, regions with high birth rates may also exhibit factors such as lower access to family planning services, cultural norms favoring larger families, and a younger age structure, which collectively contribute to sustained population increase. This is in contrast to low birth rates and high death rates, which typically indicate population decline or stability rather than rapid growth. A stable population age structure does not align with rapid growth either, as such a demographic pattern would imply fewer births or a balance between births and deaths. Therefore, high birth rates are a defining characteristic of populations that are experiencing rapid growth.
