Abstract

Water providers have an ongoing need for estimates and forecasts of the total population and the number of housing units and households within their service areas. While some of the water providers within Clackamas, Multnomah, and Washington counties have obtained this information periodically on an individual basis, a complete and systematic set of estimates and forecasts for all members of the Regional Water Providers Consortium has not been prepared for nearly 10 years. The Portland Water Bureau (PWB), on behalf of the Regional Water Providers Consortium, requested that the Portland State University Population Research Center (PRC) update service area boundaries and prepare population, housing unit, and household estimates and forecasts for the water service areas of the municipalities and water districts in the Consortium, as well as the wholesale customers of the PWB that are not Consortium members. A report issued in February 2014 described the process of collecting and reviewing boundaries for each provider and preparing estimates for each year from 1990 to 2013. This report includes a brief description of the procedures, methodologies, and data sources used to prepare forecasts of population, household population, housing units, households, persons per household, and vacancy rates for each year from 2014 to 2045. These data items are consistent with Census Bureau definitions, which are included in a Glossary on page 8. Appendix A contains summaries of the forecasts for all service areas for 2035 and 2045, and Appendix B contains annual forecasts in a one page profile for each service area.
