Oregon 150 concluded the state's official seven-month commemoration of the sesquicentennial on September 30.

One year ago most Oregonians couldn't pronounce "sesquicentennial." Now, as the official sesquicentennial celebration comes to a close, 83-percent of Oregonians know 2009 is the year we commemorate our 150th year of statehood.
An independent survey conducted throughout the month of August 2009 found
that 83-percent of Oregonians are aware of the state's 2009 sesquicentennial, compared to 34-percent in 2008, with nearly one-quarter of Oregonians having participated in an activity to celebrate Oregon's 150th year of statehood.
