The Consumer Price Index (CPI) is a measure of the average change in prices paid for a fixed "market basket" of goods and services purchased by urban consumers over time. It is commonly used as a measure of inflation.
Inflation in the Seattle-Tacoma-Bremerton Metropolitan Area (which includes Thurston County) closely follows that of the western United States and the nation as a whole. While inflation rates have increased since the recession, they remain below the peak seen in 2008. The Federal Reserve bank aims for an inflation rate of 2% to balance a growing economy with stable prices.
