Demographic Change: The total population of an area is a balance between two factors of change:
- NATURAL change: The difference between the birth and death rates.
- MIGRATION changes: How people move from one place to another.
The world population growth over time:
Between the 1930's to the 1950's there was a significant increase in the world population, this is what is called 'Population Explosion'.
Before the 1930's there was a steadily increasing population, this was until the population started to rise due to the significant higher number of births. These births out-weighed the number of deaths, causing an increase to the population.
The worlds popluation in 1720 was 791,000, and in 2000 it was 600,000,000.
The average prediction for the world's population in 2050 is 11,000,000,000.
