The BBM Nielsen Media Research Metered Market data provides estimates of in-home audiences on national and select local markets by utilizing Mark II/Signature People Meter methodology.
The Quebec Francophone audience is measured by BBM Canada and captures both in-home audiences, as well as out-of-home viewing by utilizing Portable People Meter technology.
National Sample:
The national data provides estimates of in-home audiences to network television programs and is based on a national sample that consists of 2,509 metered television households (excluding Yukon, Nunavut, Northwest Territories and Labrador), which is dispersed geographically in proportion to household concentration (with over sampling in the province of Quebec and all local markets) and includes both rural and urban households.
Local Market Sample:
The local data provides estimates of in-home audiences to local TV stations and is based on a Designated Market Area (DMA) sample of TV-equipped households. These meters are also dispersed geographically in proportion to household concentration. There are three local markets measured, which include Toronto/Hamilton, Vancouver and Calgary, with 800, 500 and 450 metered TV households respectively. All local metered homes make up a portion of the national sample.
Each year the People Meter sample is updated to include newly constructed housing units. The system also provides for replacement or "turnover" of sample households which have been in the sample longer than five years. Sample households are contacted at least twice a year, either in person or by phone, to update household demographics, service equipment and coach household members on BBM Nielsen Media Research People Meter procedures. Additional visits are made, as required, to connect newly acquired media devices or to investigate equipment problems.
Quebec Francophone Sample
The French-speaking audience in Quebec is measured by BBM Canada's Portable People Meter (PPM) technology, which "hears" encoded audio when a viewer is close to a TV. This type of measurement captures out-of-home viewing that the traditional in-home type of People Meter does not. As a result, the average weekly reach and weekly hours viewed numbers are higher than when measured with in-home People Meters.
There are two PPM Francophone panels: Montreal EM and Quebec Balance. Each panel consists of 400 homes. On any given day, some of these homes will not be contacted or the data withheld for technical reasons and not included in that day's viewing data. Because 400 is the desired number of homes, an oversample of between 5% and 10% is recruited. For example, if the actual panel size included a 5% over sample, the panel would consist of 420 homes. This would allow for 20 homes to be withheld or rejected on any given day, while still maintaining 400 homes in total.
BBM Canada does not employ a panel turnover policy for the PPM sample. Panelists can remain on the panel as long as they can perform reliably and want to remain in the panel.
