1. Charges PSU with city-county coordinated population forecasting (reassigned from counties)
2. PSU provides county-level forecasts annually, and;
3. Coordinated city-county forecasts every four years
4. Process is dependent on local public input and public participation

Deliverables• Annual county-level forecasts [Years 1-
4]– 50 year horizon– 5-year age cohorts by sex
• Coordinated county and city-level (UGB) forecasts [Years 2-4]– Report containing:
• Includes information for all cities and counties• Summary of demographic trends, data gathered
from surveys, information collected from city and county officials, as well as the public, and assumptions about future growth
• Short technical document specific to forecast methods employed
![Page 11: Oregon Population Forecast Program Rulemaking Advisory Committee (RAC)](https://reader036.fdocuments.in/reader036/viewer/2022062422/56813112550346895d97589f/html5/thumbnails/11.jpg)
Proposed Annual City-County Coordinated Forecast Approach
• Month 7—Release Preliminary population forecasts• Month 8—Hold 2nd public meeting:
Seek input for potential modifications Collect additional data and local input not
previously submitted • Month 9—Issue Proposed population forecasts and
begin Review Period
![Page 12: Oregon Population Forecast Program Rulemaking Advisory Committee (RAC)](https://reader036.fdocuments.in/reader036/viewer/2022062422/56813112550346895d97589f/html5/thumbnails/12.jpg)
Outlining the Challenge Process
– Commences with the release of the Proposed population forecast
– 45 day review period during which a city can “challenge” the forecast by providing additional information to support proposed change
• To be considered:1.Person or organization able to submit a formal
challenge;2.Types of data that must accompany a formal
challenge, and;3.Other considerations
![Page 13: Oregon Population Forecast Program Rulemaking Advisory Committee (RAC)](https://reader036.fdocuments.in/reader036/viewer/2022062422/56813112550346895d97589f/html5/thumbnails/13.jpg)
Population Forecasting Models• Cohort-Component model
– Disaggregates population into 5-year age cohorts and explicitly assumes:
• Likelihood of demographic events (fertility, mortality, and migration) is inextricably linked to a persons gender and age
• Housing Unit model– Population forecasts driven by total
housing units, occupancy rate, and persons per household
– Includes group quarters populations
![Page 14: Oregon Population Forecast Program Rulemaking Advisory Committee (RAC)](https://reader036.fdocuments.in/reader036/viewer/2022062422/56813112550346895d97589f/html5/thumbnails/14.jpg)
Types of Data Collected• Primary data
1. Public officials, planners, and other city personnel
2. Housing developer survey
• Secondary data– U.S. Census Bureau
• 2000 and 2010 decennial Censuses of Population and Housing
– Enumerated population by age and sex, and housing – American Community Survey (ACS)
• Migration, income, poverty, and educational attainment– Oregon Employment Department, Workforce
and Economic Research• Historical and current employment data, and projections• General economic trends• Likely future employers
![Page 15: Oregon Population Forecast Program Rulemaking Advisory Committee (RAC)](https://reader036.fdocuments.in/reader036/viewer/2022062422/56813112550346895d97589f/html5/thumbnails/15.jpg)
Types of Data Collected• Secondary data continued…
– Oregon Department of Transportation• Transportation infrastructure• Future plans
– Oregon Center for Health Statistics• Birth and death data
– Population Research Center (PRC)• Certified annual population estimates
– Oregon Department of Education• K-12 school enrollment data
– City, Regional, and County Planning departments
• Qualitative data not obtained in surveys
![Page 16: Oregon Population Forecast Program Rulemaking Advisory Committee (RAC)](https://reader036.fdocuments.in/reader036/viewer/2022062422/56813112550346895d97589f/html5/thumbnails/16.jpg)
Local and Public Input• Two meetings
– 1st meeting (Month 2)• Explain forecasting methodology and process • Gather additional data and local input • Provide background of locally-specific
demographic trends
– 2nd meeting (Month 8)• Provide officials with proposed forecast results • Seek input for potential modifications• Gather additional data and local input not
previously received

Oregon Population Estimates Program
• Population Estimates– Refers to a point in time estimate of
population in the present or in the past• Usual estimate date of July 1• Distribution of state revenue to
communities– Primary data collection instrument:
• Annual Estimates Survey– Now electronic!
![Page 19: Oregon Population Forecast Program Rulemaking Advisory Committee (RAC)](https://reader036.fdocuments.in/reader036/viewer/2022062422/56813112550346895d97589f/html5/thumbnails/19.jpg)
• Population Forecasts– An estimation of future population based
on historic and current trends, and assumptions about likely future events
– Oregon law requires counties to prepare and update coordinated population forecasts
• 20-year horizon
– Serve as the basis for growth management• UGB expansions • Planning-related issues (transportation planning,
school facility plans, and capital improvement)
Population Forecasts
![Page 20: Oregon Population Forecast Program Rulemaking Advisory Committee (RAC)](https://reader036.fdocuments.in/reader036/viewer/2022062422/56813112550346895d97589f/html5/thumbnails/20.jpg)
• June 2011—Oregon stakeholders meet to identify and address concerns specific to population forecasting and Oregon land-use laws
• Some identified issues:– Cost– Different demographic methods– City and county coordination – Outdated population forecasts– Controversial and subject to litigation
Population Forecast Workgroup

• Presentation objectives:1. What is the Oregon Population Forecast
Program?2. What do the changes in population
forecasting mean for my city?3. What are the benefits of the Oregon
Population Forecast Program?4. In the coming months, what can I expect
(in terms of process) and how can I prepare my city to be ready for these changes?
Outlining a New Way Forward for Population Forecasting
![Page 22: Oregon Population Forecast Program Rulemaking Advisory Committee (RAC)](https://reader036.fdocuments.in/reader036/viewer/2022062422/56813112550346895d97589f/html5/thumbnails/22.jpg)
• Updated, timely forecasts• 50-year time horizon for other planning
requirements• Consistent forecast methodology• Systematic incorporation of local and
public input• Reduction of challenges and lawsuits
– Adoption of PSU forecast is not a land-use decision and therefore, not appealable to LUBA
Benefits of the Oregon Population Forecast Program
![Page 23: Oregon Population Forecast Program Rulemaking Advisory Committee (RAC)](https://reader036.fdocuments.in/reader036/viewer/2022062422/56813112550346895d97589f/html5/thumbnails/23.jpg)
• Improved efficiency– Allows us to leverage data from existing
Population Estimates program
• Fully funded by state resources– Cost savings to cities and counties
