Abstract

Sherman County’s total population has declined since 2000, at an average annual rate of nearly one percent between 2000 and 2010 (Figure 1); however, Wasco UGB, one of its sub-areas, experienced population growth during the 2000s. Wasco, the most populous UGB, posted an average annual growth rate of a little less than one percent during the 2000 to 2010 period. This translated into a population increase of about 30 persons.

Sherman County’s population decline in the 2000s was the direct result of consistent net out-migration and periods of natural decreases (more deaths than births, Figure 12). The county’s aging population has contributed to an increase in deaths, which combined with a relatively steady number of births has resulted in a natural decrease for nine out of the 15 years between 2000 and 2015. While net out-migration and natural decrease were common during the last decade, in more recent years (2010 to 2015) net in-migration has occurred, bringing with it some population growth.

Total population in Sherman County is forecast to increase in the near-term (2016 to 2035), a trend that is driven by growth in the two sub-areas of Rufus and Wasco (Figure 1); however population decline is expected for the county over the remaining 31 years of the forecast period. This population decrease is the result of a growing natural decrease, which is expected to exceed net in-migration around 2030.

Sherman County’s total population is forecast to increase by about 50 persons over the next 19 years (2016-2035), but will likely see population decline of more than 80 persons during the last 31 years of the forecast period (2035-2066). Sub-areas are expected to generally follow their historical patterns of population increase or decrease over the forecast period.
