How Poll Vault finds and rates polls
Every day, Poll Vault's automated discovery engine scans hundreds of sources — major news outlets, pollster websites, RSS feeds, and more — searching for new public polling data relevant to US politics and policy. Each potential poll passes through a multi-stage review process: first, an AI screening layer evaluates whether the content contains legitimate survey data; then, a deeper analysis extracts key findings, methodology details, and metadata.
We deliberately cast a wide net. Our system is tuned to err on the side of inclusion — we'd rather surface a borderline poll for review than risk missing an important one. That's where human judgment comes in. Our editorial team reviews newly discovered polls each day, verifying accuracy, refining topic assignments, and ensuring that what reaches your feed meets our standards.
As part of this process, each poll receives a relevance score from 1 to 10. This score reflects our assessment of the poll's significance — factoring in the reputation of the pollster, the importance of the topic, and the depth of data available. Polls scoring below 3 are filtered out automatically; everything else is reviewed and available in your feed. The score is a useful guide for prioritizing what to read first.
Understanding relevance scores
Essential Reading
Comprehensive releases from the most respected polling institutions — Pew, KFF, Quinnipiac, NYT/Siena, Gallup, AP-NORC. Expect detailed subgroup breakdowns by party, age, race, and gender, rigorous methodology, large samples, and findings on major national questions. These polls often drive multiple days of news coverage.
Top-Tier Poll
High-quality polls from well-known pollsters on important topics, with clear topline findings and solid sample sizes. You'll find work from Gallup, Fox News, Harris Poll, ABC/Ipsos, and Pew here — perhaps with a slightly narrower scope or fewer subgroup breakdowns than a 10, but still among the most valuable data available.
High-Quality Poll
Reliable data from established pollsters like Marist, CBS/YouGov, AP-NORC, and Change Research. Topics are clearly relevant to US politics or policy, with usable findings and hard numbers. Some may come from news coverage of a poll rather than the pollster's own release, which can mean slightly less methodological detail is available.
Noteworthy Poll
Useful polling data with some caveats to keep in mind. This tier includes a wider range of sources: campaign and advocacy polls, state and district-level surveys, and single-question snapshots from larger outfits. The data is real and worth knowing, but may involve smaller samples, limited methodology disclosure, or an advocacy sponsor.
Specialized Interest
Polls that touch public opinion but sit at the edge of core political and policy territory. You'll find global or sociological studies from major pollsters, polls discovered through opinion columns rather than original releases, and niche policy surveys. The data is legitimate, but the topic may appeal mainly to specialists in a particular area.
Deep Cut
Data that's real but outside mainstream political polling. Expect state-level issue polls, industry-specific surveys, international research with a loose US connection, and academic studies picked up through news coverage. Worth reading if the topic is in your wheelhouse; easy to skip if it isn't.
For the Completionist
The most marginal polls in our database. This tier includes small-sample studies, consumer and trade surveys that touch on public attitudes, and polls discovered through secondary coverage with limited methodology details. These are included because they contain genuine opinion data, but they benefit the most from editorial context.
On the Radar
The floor of what our system captures. These are minimal data points — single-question survey snapshots, market research with a public opinion angle, or international studies with only a tangential US connection. They exist in our database because we'd rather include too much than miss something, and our editors review them alongside everything else.
A note on transparency: No automated system is perfect. Our AI occasionally misjudges a poll's relevance, and our editorial team catches and corrects these as part of daily review. If you ever spot a poll that seems miscategorized or mis-scored, you can flag it directly from your feed — flags are reviewed by our editors within 24 hours.
