On election night, two kinds of results circulate simultaneously: projections from broadcasters and partial figures from electoral commissions. They look similar — both show candidate names and percentages — but they are fundamentally different things. One is a statistical estimate. The other is an official count. Knowing where official election data comes from, how it is compiled, and why it changes over the course of counting night is the foundation for reading results intelligently.
Where official election data comes from
In every democratic election, the legally authoritative source of results is the national electoral commission or its equivalent — whatever body the law has designated to run elections and certify their outcomes. In Colombia, this is the Registraduria Nacional del Estado Civil. In Germany, it is the Bundeswahlleiter. In Armenia, it is the Central Electoral Commission. These institutions, not media organizations or political parties, are the source that matters.
Most national electoral commissions now publish results in real time on official websites, updating continuously as each district or polling station transmits its totals. Some publish raw data via open APIs; others publish human-readable pages that must be read and parsed. The data on those portals — however it arrives — is the official preliminary result as of the moment of publication.
The counting pipeline
Results reach the national portal through a multi-step process that explains both why counting takes time and why figures keep changing during the night:
- Polling station countWhen polls close, local officials open the ballot boxes and count votes by hand. Witnesses from competing parties may observe. The process is done publicly, and a results protocol is signed by all present.
- Protocol transmissionThe signed protocol — showing votes for each candidate and turnout — is transmitted to the district commission, often both digitally and as a physical document. In remote areas, physical transport can take hours.
- District aggregationThe district commission aggregates results from all stations in its area, reconciles any discrepancies, and forwards totals to the national commission.
- National publicationThe national commission publishes the aggregated figures on its official portal. In most countries this happens continuously throughout the night as each district reports in.
Each step introduces some delay. A polling station in a remote rural area may not transmit results for several hours after a central-city station. Reconciliation discrepancies — where the number of ballots cast does not match the number of names marked in the voter roll — must be investigated before that station's results are included. Large, complex ballots with many candidates take longer to count by hand than simple ones.
Why figures change during counting night
Official results on election night are always labelled as preliminary for good reason. They represent the count as of that moment — accurate for what has been processed, but not complete. As more stations report, percentages shift. Sometimes they shift dramatically, particularly if the early-reporting stations are geographically or demographically unrepresentative of the country as a whole.
Corrections also happen. If a counting error is discovered — a transposed number, a miscounted batch of ballots — the corrected figure replaces the original and the national total adjusts. This is normal quality control, not manipulation. Electoral commissions maintain audit trails precisely so that corrections can be traced and verified.
Some ballot types are counted after in-person votes. Absentee and postal ballots often have their own counting procedures, separate timelines, and different legal deadlines. Countries with significant overseas voter populations — Germany, Colombia, Armenia — may receive and count those ballots days after the domestic count concludes. Overseas votes are official and included in certified results, but they arrive late.
Verification and the certification process
Preliminary results become certified results after a formal verification period. The length and process varies by country. In some, certification happens within 24-48 hours; in others, the law allows weeks for challenges, recounts, and administrative review.
A recount may be triggered automatically if the margin between candidates falls below a legal threshold. Any candidate or party may also petition for a recount if they have grounds. Courts can hear electoral complaints and, in rare cases, order changes to results — though this is uncommon in established democracies and typically affects only small numbers of disputed ballots.
The certified result, once published, is legally binding. It is the number that determines who takes office, who receives party funding, and which thresholds were cleared. When ElectioMap updates a page from preliminary to certified results, we mark the change clearly.
How ElectioMap accesses and displays live data
For elections we cover live, our system fetches data directly from the official electoral commission portal approximately once per minute throughout the counting period. Rather than fetching the full dataset every time, we check a version indicator or timestamp first and only download new data when the source has actually updated. This avoids unnecessary load on commission servers while ensuring that updates reach our maps within a minute of appearing on the official source.
We display whatever the official source shows at that moment, labeled with a timestamp and the percentage of stations reporting. We do not interpolate, estimate, or fill gaps in the data. If a region has not yet reported, we show it as unreported rather than applying any statistical projection. If the official source is temporarily unavailable, we display the last successfully retrieved figures alongside the retrieval timestamp, so users can tell how fresh the data is.
We never call a winner or declare a result. That is the commission's role, not ours. Our job is to take the official figures and present them as clearly and quickly as possible — map, table, turnout, and all — so that anyone following the election can see what the official count actually shows, in real time, without having to navigate a government portal in a language they may not speak.
After the count is certified, each live election page becomes a permanent historical record. The methodology stays the same; only the label changes from preliminary to certified. You can read more about our specific data sources for each country on our Data Methodology page.
