Combined population close connected Portland, Salem and Longview metropolitan areas is 2,739,910 (2009 estimate).
Changes in house prices for the metro area are publicly tracked on a regular basis using the Case–Shiller index; the statistic is published by Standard & Poor’s and is also a component of S&P’s 20-city composite index of the value of the U.S. residential real estate market.
