Notes: Over the telephone, the question was asked in a national omnibus survey unrelated to postal activities, while online the question was a part of a survey entirely focused on postal activities. Consequently, the introduction text to the question differed slightly across modes in order to ensure that both sets of respondents had similar context when answering the question. In the online survey the question was only asked of those who had ever visited a U.S. Post Office (99% of the general public); tables here remove those not asked from the online base. Full question text for both modes is included in the presentation appendix.
