Chart the CPI core in USA.
A method for measuring core inflation. It is the consumer price index (CPI) excluding energy and food prices. There are many other methods for calculating core inflation, but this is the most popular measurement. This method has become the most widely used because food and energy prices can be very volatile, and this wide amount of movement would unfairly bias the measure of inflation.
