This model explores human population growth at global and local scales from 2026 onward (within a 100 year period). It explores the global world population while addressing local data for Durham Region and Oshawa, Canada. Each population is represented as a stock, with births acting as an inflow and deaths as an outflow. Birth and death rates are taken from current 2026 official data sources and assumed to remain constant, allowing the model to demonstrate exponential population change. Migration is excluded, so the results represent natural population change rather than a complete population forecast.
