How precise a result is

The more people we ask, the more precise the result. Groups inside a poll, such as one age band, are smaller than the whole poll, so their results are less precise: we mark small groups and do not show the smallest.

Weighting

Each poll page says whether its results are weighted. A weighted US poll is matched to US Census figures for age, gender, region, race and ethnicity, and education; political questions are also matched to how people voted in the 2024 presidential election.

A weighted UK poll is matched to ONS figures for age, gender, region, social grade and education; political questions are also matched to how people voted in the 2024 general election and the 2016 EU referendum.

Small groups

Groups under 50 people are marked * and should be read as a rough guide. Groups under 30 people are not shown at all.

Reading a difference

A gap of a few points between two groups can be down to chance. Look for bigger gaps, in bigger groups, before reading much into them.
