What the numbers say

These figures come from the optional survey people answer after building a comparison. Everything here is aggregate only, and descriptive — never a prediction. A figure is shown only when its group is large enough that a single response cannot be singled out (at least 10 responses); smaller groups are withheld entirely. You can filter by when responses were collected, and groups are never combined across those periods without saying so. See how these figures are made and how we handle survey data.
