Forecast program FAQs

  • Why are Multnomah, Clackamas, and Washington counties excluded from this program?

    • PRC will produce county-level forecasts for these three counties, as well as for city UGBs outside of Metro’s jurisdiction.  Metro is the only MPO responsible for both transportation and land-use planning, its charge requires the agency to work collaboratively with numerous agencies, and Portland metro has unique data input demands.
  • What do the changes in population forecasting mean for my city?

    • Population forecasts will be conducted on a regular basis every four years.
    • These forecasts will be comparable between different locations and times due to consistent methodology.
    • Planners will need to compile data and answer questionnaires sent by PRC.  To see an example of the general information questionnaire, click here; to see an example of a housing development survey, click here. (.pdf files)
  • What are the benefits of the Oregon Population Forecast Program?

    • The 50-year time horizon exceeds state mandates for land-use planning, allowing other agencies to use these forecasts without having to commission new reports and forecasts.
    • PRC already produces annual population estimates under the Oregon Population Estimates Program; conducting both estimates and forecasts at PRC improves efficiency and increases cost savings.
    • Forecasts are coordinated between counties and their corresponding cities’ UGBs; feedback from all concerned parties must be considered and incorporated where appropriate, minimizing formal objections to forecasts.
    • Adoption of final forecasts is not a land-use decision and thus is not appealable to Land Use Board of Appeals (LUBA), reducing legal challenges.
    • The forecast program is fully funded by the State of Oregon, granting counties and cities greater budget flexibility in meeting state land-use planning requirements.
  • Where can I find Oregon Administrative Rules (OARs) governing this program?
    • OARs (Scroll down to 577-50-0005 – 577-50-0070)
  • What is the difference between Population Estimates and Population Forecasts?
    • Population estimates provide snapshots of the current population, while population forecasts are the estimated populations for future years.  Both estimates and forecasts are part of this program and provide necessary information to help planners, public officials, private firms, and developers better understand the short and long-term implications of population growth.  To ensure that the most current population trends are considered, Oregon law requires preparing and updating population forecasts on a regular basis.
