Clackamas County is part of the Portland-Vancouver-Hillsboro, OR-WA Metropolitan Statistical Area.

At the time of its creation, Clackamas County covered portions of four present-day U.S. states and a Canadian province.

Soon after, John McLoughlin staked a land claim in Oregon City and built a house that in 2003 became a unit of the Fort Vancouver National Historic Site.

Most of the indigenous people of the Wil-lamet Valley were forcibly removed in February 1859, to the reservation of the Confederated Tribes of Grand Ronde.

Confederated Tribes of Warmsprings was established and remains a strong and vital player in actions that concern the Federal forests of the Cascades Range.

Oregon City was also the site of the only federal court west of the Rockies in 1849, when San Francisco, California, was platted.

Lake Oswego, Rivergrove and Wilsonville include areas in Washington County.

In Clackamas County, hamlets and villages are models of local land use governance for unincorporated areas.

The four hamlets in Clackamas County are Beavercreek, Molalla Prairie, Mulino, and Stafford.

Like the rest of Oregon, it has cities (which are formally incorporated) and rural communities (some of which for federal purposes are considered census-designated places).

After the completion of a process that began in late 1999, the county adopted an ordinance on August 11, 2005, which defined hamlets and villages.

Boring petitioned to become a village, but the application was rejected in a town hall referendum in August 2006.
