Ryerson Numeris Help Guide

Numeris, formerly called BBM, is a not-for-profit organization that provides authoritative data on broadcast measurement and consumer behavior data for radio and television. It is used by broadcasters and advertisers to determine ratings, viewership, and listenership by demographic, and by researchers to better understand Canadian media consumption. Numeris data is obtained through sampling, and results are generalized to the population. PPM and diary methods are used.

Please refer questions about Numeris to Librarian, Naomi Eichenlaub – neichenl@ryerson.ca

There are three methods for accessing numeris data, and different data is available through each method.


Access Method 1: Online Public Data
Select Numeris data is free to the public online, including reports for the top 30 TV shows and radio station listenership.


Access Method 2: Numeris Workstations
Two Numeris workstations are available within the Library on the main floor (2nd floor) that provide access to more robust data than is publicly available online. The workstations are available to current Ryerson University students, faculty, and staff, and require a my.ryerson login for access.

Numeris Workstation

Numeris Radio and TV datasets loaded and available for use through software called InfoSys+, which is owned by the Numeris subsidiary NLogic. An NLogic login is required to access how to manuals. This login can

take 24 hours to activate.

for InfoSys+.

The data that is available through these workstations is at least one year old, as per the agreement between the Library and Numeris. Radio data is released on an ongoing schedule, and television data on a fall/spring schedule. Numeris data accessed through these workstations is to be used for educational purposes, as per the agreement between the Library and Numeris.


Access Method 3: Print Archives
Numeris Books


The Ryerson Library has print archives of Numeris (formerly called BBM) reports from 1956 to 2009. Access to these materials is available to external community members for in-Library use. To receive access, present your photo ID to circulation staff and request the retrieval of specific years from closed stacks.
