The Library's CPI Table
The Consumer Price Index [CPI], published by the United States Department of Labor, is the most widely used measure of price changes and inflation. It represents a weighted index of a fixed market basket of goods and services and is published monthly for the Unites States and bi-monthly for the Detroit-Ann Arbor Area. There's a lot more information about the CPI at the government's Bureau of Labor Statistics website. For your convenience, the format of the CPI table on the AADL website enables users to compare price changes over a ten-year period in an easy-to-use one-page format.
