Population & Employment Forecasting

TRPC develops updated population and employment forecasts every three to five years.  These forecasts are used for transportation, sewer, water, land use, school, and other local governmental planning purposes.  They are also used by the private sector for business planning.  TRPC has been preparing these forecasts periodically since the late 1960s.

The previous countywide forecast was adopted on July 13, 2012. Population distributions to small areas such as cities, towns, tribes, school districts, etc. were adopted on July 10, 2015. Employment allocations were adopted on July 10, 2015.

Residential Development Survey

Did you receive a survey about how likely or unlikely you are to develop your property? TRPC estimates how many homes could be built on a parcel as part of the forecast update. But not all property owners may be interested in developing. Your response helps us to more accurately estimate where — and how much — growth is possible.

2018 Update

TRPC is in the midst of a forecast update. Countywide population, employment, and commute forecasts were adopted by TRPC in March 2018 and are now available. Small area population and employment allocations (to cities, towns, fire districts, school districts, etc.) will be available in 2019.
