Forecasts are based on census information. Planning must recognize the realities of the present and the needs of the foreseeable future. However, forecasts of population trends over a shorter time frame can be estimated with greater accuracy than over a longer period. Regional forecasts also tend to be more accurate than forecasts made for a single jurisdiction. Communities need to understand where they fit within the integrated economic unit of the region.
Population change drives future community needs.
Communities that are experiencing quickly increasing population should not plan for zero growth. It is not realistic to think that such a trend can be completely halted. A community that plans for zero growth in such a situation will likely be left with inadequate capital facilities in the future. Forecasting can help communities avoid making expensive and unnecessary investments. Unfortunately, many communities make costly decisions about their futures without considering population or economic forecasts first.
