Final answer:
A country can be underpopulated and highly developed if it has a low population density or if it has achieved a high level of development in various aspects despite its population size.
Step-by-step explanation:
In some cases, a country can be underpopulated and highly developed at the same time. This can occur when the country has a low population density, meaning there is a small population in relation to the size of the country. For example, countries with vast land areas but a small population such as Canada or Australia may be considered underpopulated. These countries may have highly developed infrastructure, technology, and education systems despite their low population.
Furthermore, a country can also be considered highly developed if it has a high standard of living, advanced industrial and technological sectors, efficient infrastructure, and a strong economy, even if its population is relatively small. The measure of development takes into account various factors such as GDP, literacy rates, life expectancy, healthcare, and education.
Overall, a country can be underpopulated and highly developed if it has a small population in relation to its size or if it has achieved a high level of development in terms of economic, technological, and societal aspects despite its population size.
