Liberals still quite strong on Nanos Index but incrementally slide (ending December 11, 2015)

The Nanos Party Power Index

  • Nanos Party Power Index – The Index which is a compilation of a series of questions on ballot preferences and the impressions of the federal leaders still has the Liberals with the strongest comparable score but sliding.  The Liberals scored 66.3 out of a possible 100 points on the Index followed by the NDP with 48.7 points, the Conservatives with 44.0 points, the Greens with 34.7 points and the BQ with 25.1 points (Quebec only).
  • Accessible Voters – Asked independent questions for each federal party as to whether they would consider or not consider voting for that party, 63.2% of Canadians would consider voting Liberal, 42.2% would consider voting NDP, 39.9% would consider voting Conservative, and 31.0% would consider voting Green.

The team at Nanos in conjunction with Klipfolio have launched our new live political data portal where you run the numbers you want and can explore the trends and data you need.  This is part of our campaign, not only to provide the most reliable data to Canadians but to let them use it as they wish. We were the first to do nightly tracking and now we are the first research organization to post live public opinion data for Canadians. Here’s the link to check it out

The views of 1,000 respondents are compiled into a party power brand index for each party that goes from 0 to 100, where 0 means that the party has no brand power and 100 means it has maximum brand power. A score above 50 is an indication of brand power for the party and its leader at this time.

The important factors in this weekly tracking include the direction of the brand strength or weakness and also the brand power of one federal party relative to another.

The data is based on random telephone interviews with 1,000 Canadians, using a four week rolling average of 250 respondents each week, 18 years of age and over. The random sample of 1,000 respondents may be weighted by age and gender using the latest census information for Canada, and the sample is geographically stratified to be representative of 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. The current wave of tracking is based on a four-week rolling average of 1,000 Canadians (250 per week) ending December 11th.

A random telephone survey of 1,000 Canadians is accurate 3.1 percentage points, plus or minus, 19 times out of 20.
