Oregon has 36 counties covering 95,988 square miles and roughly 4,222,016 residents. The state was admitted to the Union in 1859 as the 33rd state, and the current county boundaries reflect more than a century of administrative subdivision.

The largest county by land area is Harney County at 10,133 square miles, home to about 7,459 residents. The most populous is Multnomah County with approximately 794,233 residents — a density of about 1,843 people per square mile.

At the other end of the scale, Wheeler County has only about 1,478 residents.

Oregon’s capital is Salem, while the largest city is Portland — a common pattern in the United States, where many states placed their capitals in smaller, more central towns rather than their largest commercial hubs.
