The Consumer Price Index is used to calculate inflation, or the change in price of a basket of goods and services, as it impacts consumers; whereas, the Producer Price Index measures changes in selling prices, thereby expressing price changes from the perspective of the seller who produces a particular commodity.
The Center for Economic Development and Business Research released a slide presentation showing the annual inflation rate for the Midwest Region of the United States over time, as well as five-year graphs depicting the change in the Producer Price Index for aircraft, crude petroleum, natural gas, slaughter livestock, sorghum and wheat. The presentation has been updated with March data and can be accessed below.
