Spring 2011 Survey Methodology

The Reason-­‐Rupe Spring 2011 poll was conducted by telephone from March 24th-­‐April 9, 2011 using live telephone interviews and produced a nationally representative sample of 1200 adults 18 years of age and older from all 50 states and the District of Columbia. NSON Opinion Strategy conducted the poll’s fieldwork. The margin of sampling error for this poll was ± 3 percent. Interviewers were conducted with respondents on landline phones (859) and mobile phones (341). The sampling frame included landline and mobile phone numbers generated using Random Digit Dialing (RDD) methods and randomly selected numbers from a directory-listed sample. Landline respondents were randomly chosen within households based on the adult who had the most recent birthday. Samples were weighted by gender, age, ethnicity, and Census region based on the most recent US Census data. Survey researchers at NSON Opinion Strategy, Somerset Guild, in collaboration with the Reason Foundation developed the questionnaire. The survey contained 47 questions, including categorical, scale, and open-ended. Click here for full methodological details. NSON Opinion Strategy conducted the pollʼs fieldwork.
