This model shows the growth of the human population of Edmonton, Alberta over a 100 year period. The model starts with an estimated population of 1.3 million and uses birth/death rates to determine the population's natural growth.
As the population increases, the per-capita growth rate decreases. This causes population growth to slow down as Edmonton approaches its carrying capacity of 2 million people. A 10 year delay represents the time for population density to affect growth.
