This complex system displays the dynamics of Uxbridge, ON's estimated human population in the year of 2021 by use of density-dependent birth rate. Within this population model, the birth rate equals the death rate when the population of Uxbridge, ON is at its carrying capacity (birth rate = death rate). Two other scenarios can occur: When the birth rate is greater than the death rate, the population of Uxbridge, ON is below its carrying capacity (birth rate > death rate); when the birth rate is less than the death rate, the population of Uxbridge, ON is above the carrying capacity (birth rate < death rate).
Note: A complex system is one in which there may be multiple variables which affect the inflow and outflow into and out of the stock. In this specific system, the human population is the stock, and the inflow and outflow is the human population change, which is affected by the human population per capita growth rate. This variable is also impacted by the following variables: carrying capacity, human maximum birth rate, human minimum death rate. It should be noted that this complex system does not include two of the four key factors that influence alterations in population dynamics, those being immigration (inflow into the population) and emigration (outflow from a population).
