  Citation × Citation Citation Abstract Copy Title: Coordinated Population Forecast for Baker County, its Urban Growth Boundaries (UGB), and Area Outside UGBs 2016-2066 Author: Portland State University. Population Research Center, Ruan, Xiaomin, Proehl, Risa, Jurjevich, Jason R., Rancik, Kevin, Kessi, Janai, Tetrick, David, Michel, Julia Year: 2016 Baker County’s population declined between 2000 and 2010, losing on average of just over 60 people per year (Figure 1); however in recent years this pattern has changed and population increase has occurred. Between 2010 and 2015 the county added on average about 20 persons per year (Figure 2). Baker County’s population decline in the 2000s was the result of natural decrease and periods of substantial net out-migration. The larger number of deaths relative to births has led to natural decrease (more deaths than births) in every year from 2000 to 2015 (Figure 12). While net in-migration fluctuated dramatically during the early and middle years of the last decade, the number of in-migrants has been slightly more stable during recent years (2010-2015), contributing to population increase. Total population in Baker County is forecast to increase in the near-term (2016 to 2035), a trend that is driven by growth in the three sub-areas of Baker City, Richland, and Sumpter (Figure 1); however population decline is expected for the county over the last 31 years of the forecast period. This population decrease is the result of growing natural decrease, which is expected to surpass net in-migration between 2030 and 2035. Overall the county is forecast to see nearly no net change in population over the entire 50-year period, beginning the forecast at around 16,400 in 2016 and ending at about 16,400 in 2066.

Population Research Center, Rynerson, Charles, Siu, Vivian, Proehl, Risa S. Year: 2006 The North Santiam School District (NSSD) covers about 100 square miles of Marion and Linn Counties in Western Oregon, and includes the communities of Lyons, Mehama, Stayton, and Sublimity. The area served by the District has experienced sustained growth in population, housing, and public school enrollment in recent years. This report presents the results of a forecast conducted by the Portland State University Population Research Center (PRC) indicating that NSSD enrollment will continue to grow during the next twenty years. PRC’s methodology links enrollment trends with the area’s population dynamics. Population and housing are closely related to access to jobs. By itself, the District’s past growth is no guarantee of future long-term growth, but in the context of expected employment, population, and housing growth, enrollment is likely to increase at all grade levels.

  Citation × Citation Citation Abstract Copy Title: Coordinated Population Forecast for Harney County, its Urban Growth Boundaries (UGB), and Area Outside UGBs 2016-2066 Author: Portland State University. Population Research Center, Ruan, Xiaomin, Proehl, Risa, Jurjevich, Jason R., Rancik, Kevin, Kessi, Janai, Tetrick, David, Michel, Julia Year: 2016 Different growth patterns occur in different parts of the County and these local trends within the UGBs and the area outside UGBs collectively influence population growth rates for the county as a whole. Harney County’s total population has slowly declined since 2000, with an average annual rate of negative 0.2 percent between 2000 and 2010 (Figure 1). Burns is accountable for the county’s overall declining population. All other sub-areas experienced very slight population growths during the 2000 to 2010 period, increasing by a total of 32 persons. Harney County’s population decline in the 2000s was the direct result of frequent net out-migration. The county’s aging population has contributed to an increase in deaths, however, a larger number of births relative to deaths caused a natural increase for 8 out of the 15 years between 2000 and 2015 (Figure 12). Even so, net out-migration outweighed these slight natural increases, causing a slow decrease in the Harney County’s population since 2000. Total population in Harney County as a whole as well as within its sub-areas are forecast to all decrease at a slightly faster rate in the near-term (2016 to 2035) compared to the long-term (Figure 1). The tapering of growth rates is largely driven by an aging population—a demographic trend which is expected to contribute to a natural decrease (more deaths than births). As natural decrease occurs, population growth will become increasingly reliant on net in-migration. Harney County’s total population is forecast to decrease by more than 500 persons over the entire 50-year forecast period (2016-2066), a loss in population mostly happening in areas outside the UGBs. Sub-areas are expected to generally follow historical patterns of population decrease over the forecast period.
