The Bureau of Labor Statistics (BLS) studies of family living conditions rank among the oldest data collected. The first nationwide expenditure survey was conducted during 1888–91 to study workers' spending patterns as elements of production costs. With special reference to competition in foreign trade, the survey emphasized the worker's role as a producer, rather than as a consumer. In response to rapid price changes prior to the turn of the 20th century, a second survey was administered in 1901. The resulting data provided the weights for an index of prices of food purchased by workers that was used until World War I as a deflator for workers' incomes and expenditures. A third survey, conducted during 1917–19, provided weights for computing a cost-of-living index, now known as the Consumer Price Index (CPI). BLS conducted its next major survey, covering only urban wage earners and clerical workers, during 1934–36, primarily to revise CPI weights.
BLS conducted major survey revisions through the Great Depression and World War II and up through the 1970s. The need for more timely data than could be supplied by surveys conducted every 10 to 12 years—intensified by the rapidly changing economic conditions in the 1970s—led to the initiation of the current continuing survey in late 1979. Unlike the previous surveys, the U.S. Census Bureau, under contract with BLS, conducted all sample selection and field work. Another significant change was the use of two independent surveys to collect the information—a Diary Survey and an Interview Survey. A third major change was the switch from an annual recall to a quarterly recall in the Interview Survey, and daily recordkeeping of expenditures in the Diary Survey. As with the earlier surveys, the resulting data from 1979 onward have been used to revise CPI weights. For details, see the CPI Handbook of Methods.
The objectives of the Consumer Expenditures Surveys (CE) remain the same: to provide the basis for revising weights and associated pricing samples for the CPI and to meet the need for timely and detailed information on the spending patterns of different types of families.
Below is a timeline of major events in the history of BLS CE surveys. For a more detailed timeline of the continuous survey since 1979, see Improvements and protocol changes.
