Data & Graphs

Most recent data in the Irish Polling Indicator. Percentages per party.

This tab displays the 'house effects' of the polling companies for each party. A positive house effect means that a pollster structurally estimates a certain party higher than the average pollster. The dot indicates the best estimate for the house effect, the lines display the 95% uncertainty margin. Note that the x-axes are rescaled for each party to improve the interpretability of house effects.
