DIFFERENCES IN CELL PHONE ONLY HOUSEHOLDS IN LARGE VERSUS SMALL METROPOLITAN AREAS: EVIDENCE FROM OREGON

摘要

Households without landlines are a fast growing segment of the United States. Their existence challenges household survey practitioners to gather representative samples of communities in new ways. This paper looks at the demographic and travel behavior differences between cell-only households and households with landlines using the 2011 Oregon Household Activities Survey, a state-of-the-art one day household travel survey of over 17,000 households in Oregon. Authors also compare differences between cellonly households in large versus small metropolitan areas, focusing on two metropolitan planning organization (MPO) sub-samples with significant numbers of cell-only respondents: Portland and Rogue Valley. Summary statistics show that cell-only households captured in Portland were younger, of lower incomes, smaller and much more likely to locate near fixed route transit stops and in denser neighborhoods compared to the larger Portland sample. But in Rogue Valley, cell-only households were just as large as the rest of the Rogue Valley respondents but were less likely to be white, less likely to have a driver, own a vehicle, own their home and were younger. Authors also report significant travel behavior differences between cell-only and other households and how these differences varied between the two MPO samples.
