This document provides an overview of population studies. It defines population as people inhabiting a given area and discusses how population studies examine the size, composition, and distribution of populations. Population studies aim to increase population awareness and promote measures to address rapid population growth. They examine factors like fertility, mortality, and migration. Population studies provide advantages in political, economic, social, and administrative planning contexts by helping understand impacts of population changes and balance development with population growth. They also help identify regional imbalances caused by population migration trends.
