Wireless Substitution: Early Release of Estimates From the National Health Interview Survey, July–December 2018
Provides data on households that rely on wireless telephones rather than landlines. Indicates trends by providing figures for 6-month periods from July 2015 to December 2018. Includes data for nonmetropolitan compared to metropolitan areas. Telephone surveys conducted using only landline numbers could be biased if the wireless-only population differs in relevant ways from the landline population.
