Participating in NORC Research

If you have been contacted by an NORC researcher, we hope that you participate. Participants in our research studies have been scientifically selected. Your opinions and experience are important and cannot be replaced by anyone else's. The most critical component of virtually every NORC research project is you, the potential research participant. NORC is grateful for each and every person who participates in our research projects and works tirelessly to protect their privacy and rights as a research participant. NORC is an independent research organization affiliated with the University of Chicago. We conduct non-partisan research to provide information to people who make decisions on key social issues. Our research addresses important social issues like employment, education, and health care.

How to Identify NORC Field Interviewers

NORC Field Interviewers are provided with an identification badge. The front of the identification badge contains a photograph of their face, along with their name, title, ID number, and signature. The back of the identification badge includes a distinctive hologram in the upper left corner along with a phone number to call to establish whether the person is a legitimate NORC Field Interviewer. You can also call NORC at 1 (866) 287-1393 if you are ever unsure.

How to Identify NORC Telephone Interviewers

NORC telephone interviewers will identify themselves with their first and last name, as well as the name of the project or sponsor, the purpose of their call, and ask to speak with a specific member of your household. When leaving a voicemail or message on an answering machine, the NORC telephone interviewers will leave specific information, including the study name and a toll-free telephone number for that particular study.

How did your number get chosen?

Because most of our surveys need to be representative of a broad segment of the public to be valid, NORC uses a scientific selection process to identify participants. NORC typically selects participants from phone numbers or address lists of the full population to ensure a random and appropriate representation of geographies and demographics for use in obtaining study results.

NORC does not use telemarketing lists or phone books in selecting survey samples. Instead, a computer scientifically selects telephone numbers or addresses for surveys from banks of telephone numbers or USPS address lists for each geographic area. ​​​​​
