About our polling averages
Our averages include polls collected by The New York Times and by FiveThirtyEight. The estimates adjust for a variety of factors, including the recency and sample size of a poll, whether a poll represents likely voters, and whether other polls have shifted since a poll was conducted.
We also evaluate whether each pollster: Has a track record of accuracy in recent electionsIs a member of a professional polling organizationConducts probability-based sampling
These elements factor into how much weight each poll gets in the average. And we consider pollsters that meet at least two of the three criteria to be “select pollsters,” so long as they are conducting polls for nonpartisan sponsors. Read more about our methodology.
The Times conducts its own national and state polls in partnership with Siena College. Those polls are included in the averages. Follow Times/Siena polling here.
