The Telephone Point of Purchase Survey (TPOPS) was an important survey that helped determine the Consumer Price Index (CPI) that was conducted from 1998 to 2019. The TPOPS collected data about where consumers purchase goods and services and how much they were spending, in order to get a better idea of the nation's consumption habits.

Data that had been collected from the TPOPS are now collected in the Consumer Expenditures (CE) surveys.

The Bureau of Labor Statistics website offers additional information about the history of the TPOPS and its transition.

The Census Bureau has a web page “Are You In A Survey” designed to answer additional questions you might have about being in a Census Bureau survey.
