How and why is population changing?

Introduction

The world's population is spiralling out of control. This statement can be argued upon on both sides. In some parts of the world the birth rate is a lot higher than the death rate. An example of this is Afghanistan. Some reasons are there is a poor availability of doctors, nurses and medicines. Families have more children to ensure enough survive childhood. There may also be lack of contraceptives so more chance of pregnancy. These countries are in Stage 2 of the demographic transition model. This is when the birth rate is higher than the death rate. This is why the population may increase. On the other hand in some countries like Sweden and Russia the birth rate is lower than the death rate. ...read more.

There are things which are being done to stop over population. India has one of the largest populations in the world and is struggling to cope with its huge number of people. Kerala, which is a small in India, has now got a declining birth rate and a slow population growth. Women there have now got status and want to learn about education. They have also imposed a birth control. Another country to do this is China. At the current statistics the population will continue to grow rapidly until 10 billion where it will then eventually stabilise. ?? ?? ?? ?? Khawar Hussain 10R Geography Ms Rae. ...read more.
