The Weekly Nanos Tracking is produced by the Nanos Research Corporation, headquartered in Canada, which operates in Canada and the United States. The respondents are recruited from a dual frame (land + cell-lines) random telephone sample of 1,000 Canadians using a four week rolling average of 250 respondents each week, 18 years of age and over. Hybrid random telephone online survey between April 3 and July 24, 2020. The random sample of 1,000 respondents may be weighted by age and gender using the latest census information for Canada. The interviews are compiled into a four week rolling average of 1,000 interviews, where each week the oldest group of 250 interviews is dropped and a new group of 250 interviews is added. Current data is for the four week period ending January 13, 2023.
The data collection returned to the Nanos probability panel as of the week ending January 1, 2021 due to the lockdown imposed by the provincial health authorities. Data collection returned to telephone between the weeks ending March 19th and April 9th, 2021. As a result of the latest provincial lockdown the tracking returned to Nanos probability online panel between the weeks ending April 16, to June 11, 2021. Data collection returned to telephone as of the week ending June 18, 2021.
A random survey of 1,000 Canadians is accurate ±3.1 percentage points, plus or minus, 19 times out of 20.
Since voters are not actually able to make a choice between elections, it is interesting to think about party strength and support more broadly. The Nanos Party Power Index fills this need by incorporating more information than just current vote preference.
