Different areas within Oregon counties experience different growth patterns. Those patterns combine to collectively determine county‐level demographic changes. Columbia County is comprised of two types of areas: its urban‐growth boundary (UGB) areas (Clatskanie, Columbia City, Prescott, Rainier, Scappoose, St. Helens, and Vernonia) and areas outside those UGBs.
Columbia County’s total population steadily increased in the 2000s, growing at 1.3 percent annually (see Figure 1). Some sub‐areas—such as Columbia City, Scappoose, and St. Helens along the Columbia River Highway—experienced faster population growth than the county, averaging between two and three percent growth annually. In contrast, Prescott and Vernonia lost population, and …

Oregon Population Forecast Program
Different parts of the county experience differing growth patterns. Local trends within the UGBs and the area outside them collectively influence population growth rates for the county as a whole.
Columbia County’s total population has grown modestly since 2000, with an average annual growth rate of above one percent between 2000 and 2010 (Figure 1). However, some of its sub-areas experienced more rapid population growth during the 2000s. The most populous UGB, St. Helens, along with the second most populous, Scappoose, posted the highest average annual growth rates at 2.3 and 2.8 percent, respectively, during the 2000 to 2010 period. …
