The Sahel Climate Areas with temperate climates tend to be densely populated as there is enough rain and heat to grow crops e. UK Areas with extreme climates of hot and cold tend to be sparsely populated e.
Population Change The world's population is growing very rapidly. In the world's population reached 1 billion. In it reached 6 billion people.
This rapid growth in population has been called a population explosion. The major reason for population changes, whether in an individual country or for the whole world, is the change in birth and death rates. The birth rate is the number of live babies born in a year for every people in the total population. Death rates are number of people dying per people.
When birth rates are higher than death rates the population of an area will increase. Over the past years improvements in health care and sanitation around the world have led to a drop in the death rate.
Therefore the number of people in the world has grown rapidly. Life Expectancy Life expectanc y is the average age a person can expect to live to in a particular area. Life expectancy can be used as an indicator of the overall 'health' of a country. From this figure you can determine many features of a country e. As a general rule the higher the life expectancy the more healthy or developed a country is. The model is divided into four stages. Stage 1 Birth rate and death rate are high - low natural increase - low total population Stage 2 Birth rate is high - death rate is falling - high natural increase population growth Stage 3 Falling birth rate - low death rate - high natural increase population growth Stage 4 Birth rate and death rate is low - low natural increase - high total population The Demographic Transition Model does not take into account migration.
This information is displayed as an age-sex or population pyramid. This represents a high birth rate and high death rate.
Population pyramids of MEDCs More Economically Developed Countries typically have a roughly equal distribution of population throughout the age groups. The top obviously gets narrower as a result of deaths. Population pyramids for every country in the world can be found here. Population pyramids are used to show the structure of the population according to age and sex.
Some parts of the UK are very crowded. The south east, which includes the city of London, has a much greater population than the highlands of Scotland. The population is very unequally distributed over the four parts of the UK : England makes up about 84 per cent of the total population, Wales around 5 per cent, Scotland roughly 8.
The south east of England covers one tenth of the land area but has over one third of the UK population living there. The south east of England benefits from:.
