Tracking the Elusive "Cell Phone Only"

Mostly single, urban, and young, these CPOs (“cell phone onlies”) move frequently, typically renting rather than owning homes. Eschewing the hassle and cost of land lines, this breed is ever growing and making it increasingly difficult to accurately incorporate them into polling/scientific surveys seeking to measure societal characteristics and attitudes (see story). This is a growing demographic in Philadelphia; look for them to play a major - below the radar - role in civic and political life in the future.
