What is turnout propensity?

High-propensity voters and turnout propensity, defined for campaigns.

High-propensity voters are voters a campaign expects to be more likely to participate, usually because their voting history and registration signals show reliable turnout. Turnout propensity is the ranking signal campaigns use to estimate that likelihood. It helps teams prioritize outreach, but it is not the same thing as candidate support.

High-propensity voters definition

High-propensity voters are registered voters who are more likely to cast a ballot in an upcoming election based on their voting history and registration signals. Campaigns use turnout propensity scores to rank lists for outreach — GOTV, vote-by-mail chase, field, mail, and persuasion — not to predict candidate support. For searchers asking for a high propensity voters definition, the key point is that the label measures participation likelihood, not candidate preference.

A high-propensity voter list can be useful for persuasion, name ID, vote-by-mail chase, or late GOTV. The best use depends on the race, timing, geography, and campaign goal.

  • High propensity means more likely to vote, not more likely to support
  • Turnout propensity should be reviewed with geography and campaign phase
  • Lower-propensity voters can still matter for targeted turnout work

What turnout propensity is for

Campaigns use turnout propensity to sort work. It helps identify which voters are reliable participants, which voters may need turnout follow-up, and which lists are realistic for field, mail, or volunteer programs.

That makes it a planning tool. It is meant to help campaigns rank effort, not predict how someone will vote on a candidate or issue.

  • Ranks likelihood of participation
  • Supports canvassing and turnout decisions
  • Helps campaigns compare segment quality
  • Does not measure candidate support

What usually goes into it

A turnout score is often based on participation history and other visible voter-file signals such as age range, registration status, vote-by-mail indicators, or registration recency.

The exact scoring logic varies by tool, which is why campaigns should understand the method before treating the score as a serious planning input.

How CA Voter treats it

CA Voter keeps turnout propensity tied to visible campaign signals so operators can inspect why a voter lands in a higher or lower tier. The goal is to make prioritization easier to review before a list is exported.

That keeps the score grounded in campaign workflow rather than turning it into an opaque label.

How campaigns turn propensity into a list

A score becomes useful only after the campaign combines it with geography, timing, message, and outreach capacity. A high-propensity list for a city council race may be very different from a turnout universe for a school board or county contest.

The practical workflow is to compare tiers, inspect the voter count, and decide which list belongs in canvassing, mail, phones, or late GOTV work.

  • High-propensity voters for reliable turnout or persuasion universes
  • Lower-propensity voters for targeted turnout follow-up
  • Geography filters so the list matches the race boundary
  • Segment counts before field or mail budget is spent

Questions

Is turnout propensity the same as support?

No. Turnout propensity estimates likelihood to participate. It does not estimate whether someone supports a candidate or measure.

What is the definition of high-propensity voters?

High-propensity voters are voters a campaign expects to be more likely to participate, usually because prior voting history and other voter-file signals point to reliable turnout.

Can campaigns use turnout propensity for canvassing?

Yes. It is commonly used to prioritize persuasion, turnout, or supporter-contact lists depending on the campaign goal.

Does CA Voter explain the score?

Yes. The product is designed to keep the underlying ranking logic inspectable enough for campaign review.

Are high-propensity voters always the best target?

No. High-propensity voters are often easier to reach or more likely to participate, but the best target depends on the race, message, budget, and whether the campaign is doing persuasion or turnout.

Can turnout propensity help local races?

Yes. Local races often need to prioritize scarce field and mail capacity, so turnout tiers can help campaigns decide which voters to contact first.
