Australia's population

1. The study of statistics such as births, deaths, income, or the incidence of disease, which illustrate the changing structure of human populations
2. 2002/2003. By 2050 the population is expected to meet 42 million
3. 315 000
4. Decrease in predators and increased food resources. I think that these reasons for increase are bad examples for a first world country like Australia, so none of these could really be attributed to the percentage of population in Australia.
5. 1.78
6. 2.1. This compares as being very low compared to later years after WWII were the population literally exploded because of the peace people had because of no threat of war.
7. Declining and is almost starting to plateau
8. 2.6 people per house for Australia. 2.95 people per house for the USA
