Consumer Price Index
The Consumer Price Indexes (CPI) program is a national survey that produces monthly data on changes in the prices paid by urban consumers for a representative basket of goods and services. The program is maintained by the U.S. Department of Labor, Bureau of Labor Statistics (BLS).  The CPI tracks changes in prices of all goods and services purchased for consumption by urban households.  Prices for the goods and services used to calculate the CPI are collected in 87 urban areas throughout the country and from about 23,000 retail and service establishments. Data on rents are collected from about 50,000 landlords or tenants.  To access CPI data, please use our data warehouse website, or visit or contact our Data Services Staff.
