Newberg, Dundee, St. Paul see small population hikes
While Oregon's population may have increased by more than 64,000 people from 2016 to 2017, the vast majority of them are not settling in Newberg, Dundee or St. Paul.
According to preliminary estimates from an annual report on population growth by the Population Research Center at Portland State University, Newberg saw an increase of 15 residents from 23,465 people to 23,480 (0.1 percent) over the past 12 months. Dundee's population increased from 3,190 to 3,225 residents (1.1 percent), while St. Paul added five residents to increase its population from 430 to 435 residents, making it percentage-wise the top growth city in the area at 1.2 percent.
Preliminary estimates from PSU indicate the state's population increased by 64,750 people between 2016 and 2017, according to a release. That increase was primarily due to people moving into the state. The state's overall population now rests at 4,141,100, up from 4,076,350 in 2016. The increase is similar to what the state experienced from 2015 to 2016 at about 1.6 percent, the largest numerical growth over a two-year period since the early 1990s.
According to Charles Rynerson, the author of the PSU study, population growth can be attributed to two factors: natural increases — the number of births minus the number of deaths, and net migration — people moving into the state versus those moving out. Net migration, the study found, was responsible for 88 percent of the increase in population in the state.
As the state's population ages and the birth rate declines, natural increase now contributes less to the Oregon's population growth than any time since the 1930s. In fact, the net migration has been accelerating in the state markedly over the past five years, adding more than 200,000 new residents.
As one would expect, the three most populous counties in the state are in the Portland metropolitan area. Multnomah and Washington counties each added more than 12,000 residents; Clackamas County tacked on an additional 8,000 residents. By percentage, the central Oregon counties of Deschutes (3.6 percent) and Crook (2.4 percent) experienced the most growth.
The tiny town of Seneca in eastern Oregon was recognized in the report as the city seeing the greatest decline in population, as the town's population decreased from 215 people to 160 for a drop of more than 25 percent. North Plains, from a percentage standpoint, saw the greatest increase in population, increasing from 2,015 to 2,980 people, a 47.9 percent gain. City officials attributed the gain to the opening of two large subdivisions in town in 2017.
Yamhill County saw an increase in population from 104,990 to 106,300 individuals from 2016 to 2017, an increase of 1.2 percent and 1,380 individuals.
Deschutes County was the top gainer of all Oregon counties, increasing from 176,635 to 182,930 residents, a 3.6-percent jump. Economically-depressed Grant County saw the smallest gain in the state, adding five residents to increase its population to 7,415.
