Different Inflation Measures, Different Purposes

The inflation measure most often mentioned in the media is the Consumer Price Index for All Urban Consumers (CPI-U), which tracks the average change in prices paid by consumers over time for a fixed basket of goods and services. In setting economic policy, however, the Federal Reserve Open Market Committee focuses on a different measure of inflation — the Personal Consumption Expenditures (PCE) Price Index, which is based on a broader range of expenditures and reflects changes in consumer choices. More specifically, the Fed focuses on "core PCE," which strips out volatile food and energy categories that are less likely to respond to monetary policy. Over the last 10 years, core PCE prices have generally run below the Fed's 2% inflation target.

Approximate inflation ranges, from 2010-2020: CPI-U as high as 4% to as low as 0%, core PCE as high as 2% to as low as 1%.
