How these numbers work

Accuracy covers polls taken in the final three weeks of races from 2016 to 2022, from FiveThirtyEight's open archive of polls matched to certified results (CC BY 4.0). Average error is the mean absolute difference between the poll's margin and the actual margin. The adjusted error shrinks it toward the field average (k = 15 polls) so a short hot streak can't outrank a long record, and the ranking uses it. Bias is the average signed miss: D+ means the polls were more favourable to Democrats than the result, R+ more favourable to Republicans.

Polls are listed under the firm that conducted them, even when the source names a media partner first (for example "The Economist/YouGov" or "CNN/SSRS"). Full method on the scorecard and methodology pages. Something wrong? Report it through the corrections page.
