Comparatively, the two most populated counties in the state are Multnomah at 807,555 and Washington at 588,957. Much of Oregon's population is concentrated in the Willamette Valley from Eugene to the south through Corvallis, Salem, and Portland, the largest city. This makes Oregon only the 39th most densely populated state in the country. However, parts of this vast landscape are dominated by geographical features that are unsuitable for major settlement and as a result, there is an average of just 39.9 people living in every square mile of Oregon territory. Geography plays a huge part - mountain ranges and vast forest areas are just two of the geographical features that have an impact on population density in Oregon. The northwestern state of Oregon is the 9th largest in the US in terms of land area, but it has a sparsely spread population by comparison. That’s a sizable 12% rise in the numbers declared ten years earlier. At that stage, it was confirmed that the Beaver State was home to 3,831,074 residents. To establish the Oregon population in 2018, it's important to first look at the numbers from the last official US Census which was carried out in 2010. Oregon's 2013 population was estimated to have grown to over 4 million, making Oregon the 27th most populous state in the country. Oregon currently has a growth rate of 0.89%, which ranks 22nd in the country.
