What is the difference between CPI & PCEPI?

The standard CPI and PCEPI measures of inflation shown in the first chart are often called “headline” inflation rates, in contrast to “core” measures of inflation—core CPI and core PCEPI—that exclude the direct contributions of energy and food prices. Core inflation is often described as a measure of “underlying” or “trend” inflation.
