Before I started writing this blog, the topic of demography usually came before my consciousness (through the media, in conversations etc) in the following form: The world has a problem in that its population is growing too quickly. The world’s resources are inadequate to support this huge population. Unless something is done, there will be a major crisis – there will be food shortages and many people will die of starvation. This could also lead to wars over food resources. The answer therefore, is to “do something”. What though? Implement a Chinese-style one child policy? Encourage, sterilisation, contraception and abortion? Tax people according to the number of children they have? Encourage euthanasia of the old and sick?
