Oregon Population Growth Continues in 2004

Oregon’s state population grew at a rate of 1.2 percent in 2004, according to estimates prepared by the Population Research Center at Portland State University.

The center’s final certified estimates indicate that the state’s population grew to 3,582,600 for the year ending July 1, 2004, an increase of 41,100 people, or 1.2 percent, from the year ending July 1, 2003, which saw a gain of 36,800, or 1.1 percent.

Hot Time in the City: Researchers Examine Role of Human Behavior on Urban Climate

Researchers at Portland State are taking the lead in analyzing to what extent human behavior impacts urban climates, and assessing the role that public policies play in affecting heat waves and episodes of poor air quality.

The project, "Complex Interactions Among Urban Climate, Air Quality, and Adaptive-Reactive Human Response," is funded by a $1.7 million grant from the National Science Foundation's Biocomplexity in the Environment initiative, and runs from September 2004 though February 2009.
