Consumer Price Index

Use of alternative collection modes in the CPI

With the release of March 2019 data, the BLS is expanding the use of respondent reported data via a corporate dataset rather than traditional in-store/website collection. This, along with BLS research on current and future uses of alternative data sources, is discussed in more detail in the Big Data in the U.S. Consumer Price Index: Experiences and Plans draft paper posted on the National Bureau of Economic Research website and presented at the recent conference: Big Data for 21st Century Economic Statistics.
