Population Geography The study of the spatial variations in the distribution, composition, migration, and growth of populations and how they are related to the nature of places.
Stages of Population Growth 1.Low Growth: Birthrate and death rate are high but equal As healthcare improves, the death rate declines Ex. Ye long time ago 2.High Growth: Birthrate still high, but death rate declines causing rapid population growth Ex. Started in Industrial Revolution Many African countries are still here 3.Moderate Growth: The birthrate drops and most children live to adulthood Family size decreases as children live longer Ex. Developing countries, Mexico 4.Low Growth: Birthrate and death rate are low and relatively equal. Some countries may experience zero growth Ex. Most developed countries like US, Canada, Japan
Population Pyramids A graphic device that shows sex and age distribution of a population. Allows geographers to examine how events in society such as wars, famine, or epidemics affect the population of a country or region.
Population Distribution The world’s 7 billion people are not evenly distributed – 90% of the population live in the Northern Hemisphere – ¼ of the world’s people live in East Asia – ½ of the world’s people live in either Asia (mostly South & East)
Migration Migration alters the distribution of population Push Factors: reasons people leave their homeland and migrate to another region – Examples? Pull Factors: draw or attract people to another location – Examples?
Population Density Measures the number of people per square mile
