Summary of changes
Activity on this program started: June 2000
Sampling - Starting with reference year 2015 the sampling unit has changed from enterprise to establishment. The establishment is defined as the smallest operating entity for which records provide information on the cost of inputs employed to produce the units of output. Sampling at the establishment level allows for more detailed representation of large accounting firms operating in multiple regions and markets.
Coverage of the industry has not changed.
With this release of data for 2011, the ASPI has been converted to 2010=100, with 2010 as the base year. The weights used in the compilation of the index have not been updated and reflect the 2010 revenues from the sale of accounting services.
