Deschutes and Crook counties had the highest rates of population growth in Oregon from July 2016 to July 2017, according to a preliminary report released from Portland State University’s Population Research Center.

Deschutes County’s population is estimated to have grown from 176,635 to 182,930, a 3.6 percent increase and the highest rate of growth in the state. In Crook County, the estimated population grew from 21,580 to 22,105, a 2.4 percent increase.

Washington County, in the Portland-metro area, was the third-fastest growing county with a 2.1 percent increase.

The report noted Bend had the second largest population gain for an Oregon city behind Portland. Bend added 3,265 residents in one year to reach 86,765 residents, according to PSU. That equals about 9 new people in Bend per day.

Portland gained 11,705 residents in that time, or about 32 people per day.

Each year, Portland State’s research center prepares the population estimates using mostly data from housing permits and housing developments. The preliminary numbers are sent in November to the state and local governments for review. The numbers are then revised and certified by Dec. 15 for a final report published in the spring.

Portland State’s estimates for Bend are traditionally more conservative than the U.S. Census Bureau, which recently estimated Bend’s population above 90,000.

The Census Bureau compiles its estimates through different data than Portland State, including federal tax records, Social Security information and changes in driver licenses at the DMV.

Both population reports offer a good range for planning, according Bend Assistant City Manager Jon Skidmore.

Skidmore has pointed to the city’s work on its urban growth boundary expansion and its plans to upgrade water and sewer infrastructure and roads as ways the city has addressed the continued growth.

The city is predicting and preparing for 30,000 more residents by 2028.

Statewide, Portland State’s preliminary report estimates Oregon added 64,750 residents between July 2016 and July 2017, a 1.6 percent increase. That brings the state’s estimated population to 4.1 million people. Migration from other states accounted for most of the newcomers to Oregon.

The three largest counties in the Portland-metro area — Multnomah, Washington and Clackamas — had the highest increase in population, the reported showed. Multnomah and Washington each added about 12,000 residents and Clackamas added about 8,000.

As for the smallest growth in the annual report, Grant and Sherman counties each added five people.
