Oregon's population grew at an average annual rate of 1.81 percent during the 1990 to 1998 period. The total population increased by 425,000 during the eight-year period, reaching a population of 3,267,550 on July 1, 1998. Current annual rates of growth are above the U.S. national average of 1.04 percent.

Most of the way through the 1990s, the Oregon counties experiencing the fastest average growth rates are located along the 1-5 corridor and in central Oregon. The 1-5 counties include the area in the Willamette Valley and several areas in southern Oregon. The central Oregon counties are located along the eastern flank of the Cascades.

Almost all of the localities in these rapidly growing area are included in the Portland, Salem, Eugene-Springfield metropolitan areas. The exceptions -Deschutes and Jefferson counties -- may well become metropolitan areas after the 2000 census enumeration.

The few rapidly growing localities located outside the 1-5 corridor are special cases. Fairly rapid population growth has been occurring in Central Oregon, centered on Bend. This area has derived strong growth from in-migration.
