Why it matters
Cambridge elects at large by ranked choice, so a precinct's turnout and a councillor's mandate are not the simple relationship they are in a ward system. Reading the result correctly requires the transfers, not only the first choices.
Scope
At-large representation, precinct turnout, first choices and transfers, policy actions, participation reach and verified neighborhood evidence.
How it is measured
Certified results only. Turnout uses registered voters and the citizen voting-age estimate separately, and the uncertainty in the estimate is shown rather than hidden, because the two denominators give different answers.
Measures
Cambridge elects all nine city councillors at large by proportional representation, so a first-choice total does not decide a seat and there is no single correct answer to how many people voted. This tracker shows the counting rules first, then every official ballot total and every precinct's turnout against the denominator it was actually divided by. One turnout figure is publishable today, against registered voters. The versions measured against the citizen voting-age population and against total population are gaps, not estimates, because their denominators are Census figures that have to be read with their margins of error before any quotient built on them means anything. What the Council has officially done is kept in a lane that is never joined to what neighborhoods say about it.

Rules of the count
Seats on the City Council
No denominator — this is a count fixed by the charter, and dividing it by anything would turn a constant into a rate that nothing publishes
How this is measured
seats · None. A charter constant rather than an estimate. Two independent official pages state it identically, and the count report header states the same number as the number of candidates being elected.

Length of a Council term
No denominator — a term length is a duration, not a share of anything
How this is measured
years · None as published, but flagged for re-check. The same Commission page records that the City voted in 2025 to adopt a new charter, and does not state when that charter takes effect. The term length is published as current today; the effective-date question is carried as its own gap and is shared with the petitions module rather than restated here.

No denominator — a seat count fixed by the charter has no denominator
How this is measured
seats · None. Carried because the School Committee contest sits on the same ballot and has a materially different invalid-ballot rate, so omitting it would let a reader generalise the Council's rate to the whole ballot.

- How a surplus above quota is transferredRandom, every nth ballot (Cambridge style); avoid exhausted ballots if possible; elected immediately (after the 1st count)
- Whether that method is changingThe Cambridge Charter passed in 2025 allows the Board of Election Commissioners to change the method for selecting ballots to transfer from a candidate’s surplus to bring the candidate down to quota. Regulations will be voted on regarding any changes at least 6 months before the 2027 Municipal Election.

No denominator — a count of published locations is not a share of anything
How this is measured
published result sets · This is our own observation of the published record on one date, not a figure the Commission states, and it is badged accordingly. A location that stops answering later would change it, which is why the method names the date rather than treating the result as permanent.

The formula uses identified inputs and the method is reproducible.
Method: Counted by requesting each official count-report location named on the certified results page on the read date and counting those that answered. The Commission does not publish this number; it is our own observation of its record.

The Commission's stated reason for the correction
No denominator — a statement is not a quantity
How this is measured
published statement · None as to the wording, because it is transcribed rather than summarised. The Commission does not state which figures moved or by how much, and no such detail is inferred here from the difference between the published sets.
During the Municipal Election, a technician error produced a discrepancy in the City’s preliminary unofficial results that were generated on Election Day. This discrepancy was subsequently identified by the Election Commission Staff and an Election Auditor hired by the Election Commission. The discrepancy was then verified, accounted for, and corrected in advance of the updated unofficial results that were shared November 7 and all results shared thereafter.

When the certified report was generated
No denominator — a timestamp is not a quantity
How this is measured
report timestamp · None. Carried because a result set is identified by when it was produced, and every figure on this page should be attributable to one identified run of the count rather than to a page that may change.

These name the record that would answer them and, where we have looked, when we last checked. Several are not merely unconnected but impossible to compute from anything published today; the measure says which.
Turnout, and the three things it can be measured against
- Turnout against the citizen voting-age proxyMissing
- Turnout against total populationMissing
First choices, and what the transfers decided
- Candidate first choices by ward and precinctMissing
- The full transfer ledger, count by countMissing
Turnout by ward and precinct
- A precinct map of these figuresMissing
Certification, and the correction
- The Commission's reconciliation of the four ballot totalsMissing
What the Council has done, and what neighborhoods say
- Official actions taken by the elected bodyMissing
- Neighborhood evidence on the same subjectsMissing
How these are measured
- Why four totals describe one election
- Voters are recorded at check-in; ballots are processed contest by contest; the ballot question is recorded separately again. Those are four different events, so they produce four different numbers, and each is correct for the question it answers. The differences between them are published as arithmetic and left unexplained, because no source held here explains them.
- Why turnout has three denominators and no single answer
- Registered voters, the citizen voting-age population and total population answer three different questions about the same ballots: reach among people already registered, participation among people entitled to vote, and reach across everybody who lives here. Only the first is an administrative count, and only the first can be published today. They are shown side by side, never averaged, and no combined figure exists anywhere in this module.
- Counts and estimates are different kinds of number
- Every figure this tracker publishes today is an administrative count or a quotient of two administrative counts, so nothing here carries a sampling error and nothing here carries a published interval. The moment a survey estimate enters as a denominator, that stops being true, and the interval has to travel with the quotient. That is the whole reason two of the three turnout measures are gaps rather than numbers.
- What was checked before anything was published
- The published precinct rows add to the printed citywide totals for both registered voters and voters turned out. Valid and invalid ballots add to ballots processed in each contest. The three ballot-question rows add to the ballot-question total. The published quota reproduces from the published quota rule for both contests. The elected councillors' final totals and the exhausted pile account for every valid ballot. Where any of those had failed to reconcile, the figure would not be here.
- How the highest and lowest precincts were chosen
- By comparing the unrounded quotient for every published row, not by reading the City's rounded percent column. Selecting on the rounded column picks the wrong precinct here, because two rows print the same whole percent and the higher of the two is not the one that column suggests. The endpoints size a spread; they are not a ranking, and no precinct between them is ordered or characterised.
- Why a final total is not a measure of support
- Under proportional representation everything a candidate holds above the quota is transferred away, so every elected councillor finishes the count on exactly the quota. A final-count total therefore records that a seat was won and says nothing about how much support won it. What the counts do show is when each seat was settled, which is why the roster records a count number rather than a vote total.
- How a corrected result is handled here
- All three published result sets are named and linked so the change can be audited, and only the certified set supplies figures. The Commission's own account of the correction is quoted rather than summarised, because a paraphrase of why an election result changed is the one sentence on this page that has to be quoted or omitted. The superseded sets' values are never republished as figures.
- Why the two lanes are never joined
- There is no record anywhere in this module that links an official action to a neighborhood submission, and no field on either type that could hold one. They share a subject vocabulary and nothing else. The same subject is not the same claim, and two things appearing together is not evidence that one caused the other. Arguing that it did belongs in the Civic Forum, which is a different place with different rules.
What you can do about it
Read the certified results yourself
The Election Commission publishes the certified result set, the ballot-question tallies and its own account of the correction on one page. Everything on this page is read from it and from the count reports it links.
