Introduction

Geography - Human Revision The distribution of global population Reasons for area being sparsely populated - Countries with unstable government tend to have lower population densities as people migrate, e.g. Afghanistan Human - Limited job opportunities causes some areas to be sparsely populated because people leave the area, e.g. Amazon Rainforest Human - High land that is mountainous and inhospitable makes people leave the area because you can't grow crops and you can't build roads. Physical - Areas with extreme climate of hot or cold tend to be sparsely populated because you cannot grow crops and this major problem relating to starvation. Physical - Areas with few resources tend to be sparsely populated , e.g. The Sahel Physical Reasons for area being densely populated - Countries with stable governments tend to have high population density, e.g Singapore Human - Low land which is flat is good for farming therefore allows better growth of crops, e.g Ganges Valley in India Physical - Areas with temperate climates tend to be densely populated as there is enough rain and heat to grow crops, e.g UK Physical - Good job opportunities encourage high population densities in large cities in HICS e.g New York and LICS (Nairobi) ...read more.

Conclusion

They all have a population density of less than 10 people per square kilometre. The most densely populated areas are coastal areas and the fertile floodplains of the major rivers, like the Yangtze, found in the east of the country. Climate is another important physical factor which affects the density of population. The climate of China is very diverse, from arid to monsoonal. Large cities like Beijing and Shanghai do not get extreme climates and is one reason for their continued growth. There are no large settlements in the arid desert areas or the very wet and cold mountains. Human In China the richer areas that have more industry also have higher population densities. These areas are accessible with good communication links which has encouraged the growth of industry and population. In the 1970s the Chinese government introduced a strategy for coastal economic development. This led to rapid economic development along the south-east coastal area, which drew in workers, making it now the most densely populated region based around Shanghai. The densely populated major ports are situated on the coast where they trade with the rest of the world. They are centres of industry. The density of population in the UK ...read more.
