Nielsen Data Sets

Eligibility for access to Nielsen Datasets is strictly limited to:

  • UCI tenured and tenure-track faculty
  • UCI PhD students
  • UCI postdoctoral researchers

Eligible faculty may also use the data for teaching purposes of undergraduates or master’s level students. The faculty member must accept full responsibility for the student’s use in the classroom or independent study.

PhD students or postdoctoral researchers are required to name an advisor, who must be a full-time tenured or tenure-track professor from the subscribing institution.   Both parties must register individually.

Access Instructions for Eligible Users

  1. Read all Project Criteria, Use Requirements, and Papers & Publication Policies.
  2. If PhD or postdoctoral researchers will access Nielsen data, then both the advisee(s) and advisor need separate registration codes
  3. To request registration code(s), please complete the online code request form on the page that follows, after you submit your agreement to the Policies.  
  4. After the administrator approves your request for a code, you will receive an email with your registration code and instructions to complete the process. The Kilts Center will review your project(s) and send you a final activation email along with steps for how to access the data.
  5. Annette Buckley, Research Librarian for Business & Economics, is UCI’s Nielsen administrator, and typically approves code requests within 48 hours during the business week.  If you have not received an update after 48 hours, Annette may be out of the office.  After 48 hours, please use UCI’s Ask A Librarian email service, and ask library staff to visit this file path:  T:\Reference\Nielsen Dataset Registration Codes



Release Schedule
According to staff at the Kilts Center for Marketing, the datasets are released simultaneously and on a one-year lag; i.e. a 2020 release would be 2018 data.  The release date will vary, depending on both when the Kilts Center receives the data from Nielsen, and how long data cleanup takes.
