By the U.S. Department of Labor, Bureau of Labor Statistics. The Consumer Price Indexes (CPI) program produces monthly data on changes in the prices paid by urban consumers for a representative basket of goods and services.
Price indexes are available for the U.S., the four Census regions, size of city, cross-classifications of regions and size-classes, and for 26 local areas. Indexes are available for major groups of consumer expenditures (food and beverages, housing, apparel, transportation, medical care, recreation,education and communications, and other goods and services), for items within each group, and for special categories, such as services.
Monthly indexes are available for the U.S., the four Census regions, and some local areas. More detailed item indexes are available for the U.S. than for regions and local areas.
Indexes are available for two population groups: a CPI for All Urban Consumers (CPI-U) which covers approximately 87 percent of the total population and a CPI for Urban Wage Earners and Clerical Workers (CPI-W) which covers 32 percent of the population.
Some series, such as the U.S. City Average All items index, begin as early as 1913.
