What modes have been used to collect HINTS data?
HINTS 2003 and 2005 were administered by telephone using a random-digit-dial (RDD) sample frame. HINTS 2007 was administered in two different modes. One was by telephone, with an interviewer reading the questions. The second was by mail. This involved sending a paper questionnaire to the respondent’s home and asking the respondent to fill out the survey by him/herself. The telephone mode was administered by drawing a sample using a RDD sample frame. This involves randomly generating telephone numbers among those exchanges that are used for landline telephones. The sample for the mail survey was based on a list of all addresses to which the United States postal service delivers residential mail.
