Currently, the Telephone Point of Purchase Survey (TPOPS) calculates three of the four Bureau of Labor Statistics (BLS) recommended response rates using a version of the American Association for Public Opinion Research's (AAPOR) RR4. These four BLS recommended response rates are Initiation, Collection, Estimation, and Total Survey. As part of an effort to incorporate consistent definitions with other Office of Prices and Living Conditions (OPLC) surveys, TPOPS is developing new response rates that will continue to satisfy BLS recommended response rates and satisfy more program needs.
