  • Population change is controlled by migration change and natural change. Natural change depends on the birth rate and the death rate. If there are more births than deaths the population will increase.
  • migration is movement of people into and out of an area or country. If there are more incomers (immigrants) than outgoers (emigrants) there will be a gain in population.
  • Natural increase-the difference between birth rate and death rate. The more birth rate exceeds the death rate, the higher the rate of natural increase.
  • Factors contributing to the fall in mortality: Due to the development of modern medicinces, the introduction of vaccination and immusation programmes, better healthcare -more doctors and nurses, clean drinking water and better sewage disposal and better diet.
  • MANAGING POPULATIONS. For example, China's one child policy- Chinese government introduced schemes of control birth rate. No couple was to have more than one child and if they did they would of been penalised in various ways. All couples were closely monitored and given a certificate entitling them to such benefits such as cash bonuses, longer maternity leave and better childcare. Unmarried young people were persuaded to postpone marriage and women that were pregnant were pressured to have abortions. Couples who already had more than one child were virtually forced to be sterilised. Birth rate fell, particularly in urban areas because in cities, finding a living space for a family of three is difficult. Raising a child there is also much more expensive…
