Final answer:
Countries with stabilized or slowly growing populations are typically low-fertility countries with access to birth control and higher female education, such as China, Australia, and most European nations.
Step-by-step explanation:
Countries that are most likely to have either a stabilized or a slowly growing population are typically low-fertility countries such as China, Australia, and most of Europe. These countries have already undergone the demographic transition, moving from high birth and death rates to low birth and death rates, and are now experiencing population stabilization or decline. Factors contributing to this trend include widespread access to birth control, higher levels of female education, urbanization, and a shift away from agricultural professions which typically favor larger families.
In contrast, countries with high fertility rates, primarily found in sub-Saharan Africa, exhibit rapidly growing populations. These countries often face challenges such as limited access to birth control and a lack of female education, resulting in higher birth rates.
Conversely, demographic changes are also occurring in high-income nations where there is a growing proportion of elderly in the population, indicating a different set of societal challenges that come with an aging population.
