A demographic forecast is a reasonable estimate of the number and general location of houses, people, and jobs in the future. The Community Choices and Trend forecasts were prepared for use in the Communities in Motion long-range transportation plan. The forecasts are prepared in five-year increments, extend to the year 2030, and are broken down by both Demographic Areas and Traffic Analysis Zones. Forecasts are a primary data source used in the COMPASS Travel Demand Model to analyze future travel demand and transportation deficiencies.

 

Economic and Population Forecasts for Ada and Canyon Counties

The population and employment forecasts establish a framework for understanding future development patterns and transportation conditions. Communities in Motion used a valley-wide population forecast of 825,000 with a horizon year of 2030, which soon became viewed as too conservative. John Church of Idaho Economics was commissioned by COMPASS to provide a long-term population forecast based on an econometric model.  To review of excerpts from the employment-based forecast, click here.
