Study of Population
What does immigrate mean?
The prefix im- (or in-) often means "in" or "into."
Emigrate - to leave your country of origin to live permanently in another country
The prefix e- (or ex-) usually means "out of" or "from."
The study of human population dynamics. It
looks at how populations change over time
due to births, deaths, migration and ageing.
Political- Countries with stable governments tend to have a high population density e.g. Singapore. Unstable countries tend to have lower population densities as people migrate e.g. Afghanistan.
Social - Groups of people want to live close to each other for security e.g. USA. Other groups of people prefer to be isolated e.g. Scandinavians
Economic - Good job opportunities encourage high population densities, particularly in large cities around the world. Limited job opportunities cause some areas to be sparsely populated e.g. Amazon Rainforest
Relief (shape and height of land) - Low land which is flat e.g. Ganges Valley in India (high density). High land that is mountainous e.g. Himalayas (low density)
Resources - Areas rich in resources (e.g. coal, oil, wood, fishing etc.) tend to be densely populated e.g. Western Europe. Areas with few resources tend to be sparsely populated e.g. The Sahel
Climate - Areas with temperate climates tend to be densely populated as there is enough rain and heat to grow crops e.g. UK. Areas with extreme climates of hot and cold tend to be sparsely populated e.g. the Sahara Desert
It is a population pyramid showing a broad base, indicating a high proportion of children, a rapid rate of population growth, and a low proportion of older people. This wide base indicates a large number of children. A steady upwards narrowing shows that more people die at each higher age band. This type of pyramid indicates a population in which there is a high birth rate, a high death rate and a short life expectancy. This is the typical pattern for less economically developed countries, due to little access to and incentive to use birth control, negative environmental factors (for example, lack of clean water) and poor access to health care.
