2. Population Density The number of people living in a given area (usually 1 square kilometre)
3. Densely populated An area that is crowded with people. For example Western Europe
4. Sparsely populated An area that has few people living in it. For example The Amazon Rainforest
5. The Demographic Transition Model (DTM) The demographic transition model describes a sequence of changes on the relationship between birth and death rates. The model was produced using changes in the natural increase in several industrial countries in western Europe and north America. It suggests that the population growth rates for all countries can be divided into four stages.
6. Birth rate The birth rate is the number of live births in a year for every 1000 people in the total population
7. Death rate The death rate is the number of people in every 1000 who die in a year.
10. Elderly Dependents Many of the elderly dependents have to live alone especially women as their married partners have died. Most cannot afford the cost of residential homes which in some parts of the country can cost over £2000per month. Some people have to give up their lifetime savings and sell their own homes just to get residential homing. There are long waiting lists for hospitals for operations such as hip replacements. Those living in urban areas are fearful of crime and traffic.
11. Pull factor The reason why people are attracted to or want to move on to a different area. These are usually positive or preserved to be.
12. Push factor The reason why people want to leave an area these are usually negative
15. One Child Policy The problems of the of the one child policy. When it was 1940 China encouraged the people that lived there to have more than one child. The two main reasons are military strength if they had more babies then the children will have jobs. The second reason is agricultural problems as more babies were born the more problems the agriculture would get. There was a 55 million population increase every three years. The solution. In 1979 the state decided to try and control population growth and stabilise the number. To do this it forcibly introduced the one child per family policy and set the marriage age for men was 22 and females 20. Couples had to apply to get married and to have a baby. Exceptions to the one child policy Rural areas are allowed a second child. Ethnic minorities are allowed up to four children. If the first child dies then you are allowed another child. Families who have children with mental or physical difficulties are sometimes allowed another child.
16. Youthful dependents They put a strain on LEDC’s because of the high levels or education provision and health care are needed for children and babies. Most LEDC’s cannot afford this. A population explosion is inevitable as these young people reach child bearing age. The rapidly growing population need housing and employment when they grow up e.g. India
17. Migration Migration is when some people move from one area of the world to another or from one city to another city.
