A country that has stable populations is characterized by an age structure that is relatively balanced, with a similar proportion of individuals in different age groups. This indicates that the birth rate is approximately equal to the death rate, resulting in a stable population size over time. Additionally, stable populations may also have a low migration rate, as there is no significant influx or outflow of individuals that could significantly impact population stability.
Demographers collect and study data about the age structure, geographic distribution, and growth rate of human populations. They use this information to analyze trends, make projections, and inform policy decisions related to population dynamics. This field of study is crucial for understanding social, economic, and environmental changes at local, national, and global levels.

Osteologists study bones, primarily focusing on skeletal remains to gain insights into past human populations. They analyze bone structure, density, pathology, and age to understand health, lifestyle, and evolutionary patterns of ancient and modern populations.
