Population geography examines how population distribution, composition, migration, and growth relate to places. It also considers underpopulation and overpopulation. Overpopulation occurs when the human population exceeds the environment's carrying capacity, while underpopulation is a lower population than expected, such as in rural areas. Population changes through migration, immigration, emigration, birth, and mortality. Migration can be for economic, social, political, or environmental reasons. Immigration is the influx of people into an area, while emigration is leaving one's country. Dangers of overpopulation include illegal refugees, environmental impacts, poverty, lack of food and water, and unemployment.
