Demographics Forecasts: Population, Housing, and Employment
A demographic forecast is a reasonable estimate of the number and general location of houses, people, and jobs in the future. COMPASS develops demographic forecasts for Ada and Canyon Counties in consultation with the COMPASS Demographic Advisory Workgroup. These forecasts are developed as part of the region’s long-range transportation plans are a primary data source used in the COMPASS Travel Demand Model to analyze future travel demand and transportation deficiencies.
COMPASS forecasts 1,022,000 people and 463,000 jobs by the year 2040 in Ada and Canyon Counties. This forecast is the basis for the Communities in Motion 2040 Vision, developed in 2012, and was prepared for use in the Communities in Motion 2040 regional long-range transportation plan. This plan was adopted in 2014.
The forecast is divided into five-year increments and is reconciled annually to account for growth that has occurred since the original forecast was developed. The annual reconciliation aligns new growth with demographic areas, but maintains the same control total.

In 2019, COMPASS developed a forecast of 1,075,000 people by 2050 in Ada and Canyon Counties. This forecast will be used to develop the Communities in Motion 2050 Vision, which will be the growth and transportation scenario for Communities in Motion 2050.
Two public surveys — conducted in fall 2019 and spring/summer 2020 — provided valuable input from area residents regarding growth and transportation values and preferences. This information is being used to inform the growth patterns and transportation investments in the Communities in Motion 2050 Vision.
It is anticipated that the Communities in Motion 2050 Vision will be adopted by the COMPASS Board of Directors in spring 2021 and the Communities in Motion 2050 long-range transportation plan will be adopted by the COMPASS Board of Directors in December 2022.
The forecast will be divided into five-year increments and reconciled annually to account for growth as it occurs.
