- Apportionment Method This method assumes that the growth of a specific area (town, city) will be proportional to the growth of the larger region it belongs to (state, country). It is useful when the development of the area is expected to mirror the overall national growth. - Master Plan Method This is a planning document that outlines the long-term vision for a city's development, including land use, infrastructure, and zoning. It is not primarily a population forecasting method. - Comparative Graphical Method This method involves plotting the population growth curves of similar cities and extrapolating the curve of the city in question based on the trends of the others. It is useful for cities with similar development patterns. - Logistic Curve Method (S-curve) This method assumes that population growth follows an S-shaped curve, with an initial slow growth, followed by rapid growth, and then a slowing down as it approaches a saturation point. It is useful for cities that are expected to follow a pattern of rapid growth and then stabilization.
