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.
Lane County’s total population has grown steadily since 2000; with an average annual growth rate of just under one percent between 2000 and 2010 (Figure 1); however some of its sub-areas experienced more rapid population growth during the 2000s. Veneta and Creswell posted the highest average annual growth rates at 5.2 and 3.1 percent, respectively, during the 2000 to 2010 period.
Lane County’s positive population growth in the 2000s was the direct result of substantial net inmigration and in the early years, natural increase. Meanwhile an aging population not only led to an increase in deaths, but also resulted in a smaller proportion of women in their childbearing years. This along with more women choosing to have fewer children and have them at older ages has led to slower growth in births. The more rapid growth in deaths relative to that of births caused natural increase—the difference between births and deaths—to shrink between 2007 and 2012. Since 2012, net in-migration has outpaced natural increase, driving rising population growth rates.
Total population in Lane County as a whole as well as within many of its sub-areas is forecast to grow at a slightly faster pace in the first 20 years of the forecast period (2015 to 2035), relative to the last 30 years (Figure 1). The tapering of growth rates is largely driven by an aging population—a demographic trend which is expected to lead to declining natural increase (births minus deaths). As natural increase declines and eventually becomes natural decrease, population growth is expected to become increasingly reliant on net in-migration.
Even so, Lane County’s total population is forecast to increase by nearly 67,300 over the next 20 years (2015-2035) and by nearly 152,400 over the entire 50 year forecast period (2015-2065). Sub-areas that showed strong population growth in the 2000s are expected to experience similar rates of population growth during the forecast period.
