"Urban Sprawl" in Pullman?

Nope, not according to the U.S. Census Bureau:

Many of Washington's metropolitan areas have grown substantially since 2000, with the Tri-Cities, Bellingham and Olympia showing the highest percentage growth, the Census Bureau reported today.

The state's smaller communities, called micropolitan areas, also showed solid growth, the agency said.

[...]

Micropolitan areas also showed steady growth. Ellensburg grew 15.5 percent and Shelton 14.1 percent between 2000 and 2007.

Moses Lake, with 83,047 residents, was the largest of those and grew 11.2 percent. Pullman (1.2 percent) had the smallest growth rate.

In fact, Pullman had the smallest growth rate of all metropolitan and micropolitan areas in Washington.
