2017 Projection Update

Pursuant to RCW 43.62.035, OFM is updating the Growth Management Act (GMA) projections in the fall of 2017.

The timeline for the fall 2017 GMA projection update is available here.

As a first step, OFM has reviewed and evaluated the 2012 GMA projections. The documents provided below show how well the 2012 GMA projections are tracking OFM’s current April1 population estimates and present a framework for updating the projection model’s fertility, mortality and net migration assumptions.

OFM plans to engage local planning experts and stakeholders during the evaluation and review process. If you wish to be included in the email distribution list, or need to change your contact information, please contact Rachel Hughes at 360-902-0599 or pop.gma@ofm.wa.gov.
