Update: 2013 and 2014 paid circulation numbers here.
The September 2011 Audit Bureau of Circulations (ABC) report shows a 6.7% drop in Oregonian circulation from six months previous.
Circulation reported in March 2011 was 260,248. For September 2011 it has fallen to 242,784.
Changes ABC made in the March 2011 circulation report (such as adding e-edition circulation to print circulation figures) gave the Oregonian an 8.86% spike in total circulation (from 239,071 to 260,248) over the preceding September 2010 report. But now the Oregonian is back near where it was in September 2010 before the expanded counting began.
Adding e-circulation was a good idea because it measures a new form of readers. Still, readership is not increasing for the Oregonian. The Oregon paper has lost more than 1/5th (68,000) of its circulation in five years and more than 1/4th (90,700) in six years.
September 2005 circulation - 333,515
September 2006 circulation - 310,803
September 2011 circulation - 242,784
