Oregon's city-dwelling population grew in 2010

In 2010, Oregon's population was approximately 3,844,000. It increased by 20,700, or 0.5 percent, from 2009. Since 2000, Oregon's population has grown by 423,000 (12%).
In 2010, nearly 2.7 million Oregonians lived in an incorporated city or town. They represented about 70 percent of the state's total population. This is an increase of 400,000, or nearly 18 percent, from the start of the decade.

The total population of Oregon's 10 largest incorporated cities (see the table below) represent 38 percent of the state's population.

Though Portland tops the list, the number of people living in the incorporated cities around Portland - such as Beaverton, Gresham, Tualatin, Wilsonville, and so forth - nearly equals the total number of people living within Portland's city limits.

Oregon's smallest city (population 2!) is Greenhorn, located in Baker County.
