Deputies elected in 2022
Ministero dell’Interno — Eligendo
The deputies elected on 25 September 2022, with their list, constituency and district. Vote counts are included for single-member districts.
This is the 2022 result, not the Chamber as it stands today: it does not account for resignations, replacements or changes of group. For single-member districts the official data records the coalition that backed a candidate, not their party.

Overseas constituency seats, 2022
Ministero dell’Interno — Eligendo
The 8 Chamber seats filled in the overseas constituency in 2022, with list votes by division and the resulting seat allocation.
These are seats, not names: the ministry does not publish who was elected overseas in any open format, so the data stops at the list that won the seat. The allocation is computed by us using the largest-remainder method set out in law 459/2001, and reproduces Eligendo’s published totals exactly.

The four divisions of the overseas constituency
The four divisions into which art. 6 of law 459/2001 cuts the overseas constituency — Europe, South America, North and Central America, Africa Asia Oceania Antarctica — drawn on an equal-area world map, with the countries that make up each and the land area it covers.
Two different things with two different provenances. The coastlines come from Natural Earth, an independent cartographic project (tier 3), at 1:110m: they are there to make a continent recognisable, not to settle a border. Which division a country belongs to is ours, derived from art. 6, and checked country by country against the Interior Ministry’s own file recording each state’s division in 2022: 157 countries in common, 157 agreeing, none disagreeing. At that scale 24 states are too small to draw — Malta, San Marino, Singapore, the Caribbean islands — and they are named beside the division they belong to. Seats are not in this file: they are re-apportioned at every election and come from the 2022 result.

The Chamber today, from the Chamber’s own open data
Camera dei deputati — Dati aperti
Every deputy of the 19th legislature — those sitting and those who have left — with mandate start and end dates, constituency, list of election, and every parliamentary group they have belonged to, with the dates. It holds 414 records for 400 seats: a seat refilled mid-term leaves both names behind, and that is what lets the Chamber be drawn as it stood on any date.
Until 1 August 2026 dati.camera.it answered every automated client with a WAF challenge instead of data, which is why the Chamber’s composition came from Wikipedia. It answers now, and an official source takes precedence. One thing this source does not publish: the component of the mixed group, because ocd:componente points at empty nodes. The component therefore stays tier 3, and is labelled where it appears. This entry also named a second thing, the single-member district of a deputy who won one — that was wrong. dc:coverage does give the multi-member district even for them, but the college itself is on the election node, and the single-member winners here keep coming from the Eligendo data only because that is where the vote counts are.

The mixed group’s components, and single-member winners’ parties
The two things no official source publishes: the internal components of the mixed group — +Europa, Minoranze Linguistiche and the rest — and the party of deputies who won a single-member district, which the ministry never records: it records the coalition that backed them. The source is Italian Wikipedia, which in turn cites Pagella Politica’s roll of those elected.
Until 1 August 2026 this was the Chamber’s entire composition, because the Chamber published nothing a program could read. It does now: deputies, mandates and groups come from the Chamber’s own open data at tier 1, and what is left here is only what that data does not contain. The mixed group’s components are in the ontology but empty — the predicate exists and carries no value at all. The successions, on the other hand, are there, and this entry said for months that they were not: on 1 August 2026 the flow diagram moved to the Chamber’s data, which records who took whose seat and whether by moving up the list or by winning a by-election. Nobody publishes the party of a single-member winner: that is 141 of the 400 seats, and we accept it only where the party named is one of the lists that actually backed that candidate. This is the only data on the site that does not come from an official source, which is why it is marked “tier 3”. Before importing it we check it against the official data we already hold, and if a single check disagrees the import stops and we keep the previous data.

Senators of the 19th legislature
Senato della Repubblica — Dati aperti
Every senator of the 19th legislature, with their parliamentary group, role within it, region of election, the history of the groups they have belonged to, and the dates their mandate began and ended.
It includes senators who have left the Senate during the legislature, with the date their mandate ended; those in office today have no end date. That is what makes it possible to reconstruct the Senate on any date rather than only as it is now.

Manifesto text
Ministero dell’Interno — Elezioni trasparenti
The text of the 31 manifestos filed for the 2022 general election, page by page, with passages grouped by subject.
7 of 31 manifestos are text files and 23 are scans, read by optical character recognition and marked as such wherever they appear; of the remaining 1 there is no text at all, because they are not PDFs and the ministry’s server no longer returns them to anyone: it answers 403 to a browser too. A passage containing even one word read with low confidence is kept but never shown. The full text is not republished: every quotation links to the exact page of the PDF on the ministry’s site.

Registered symbols and manifestos

Symbols filed with the Interior Ministry in order to stand, with the party leader, who filed the symbol, and links to the official documents: electoral manifesto, party statute and transparency filing.
These relate to the election of 25 September 2022. The documents stay on the ministry’s servers: we link to them rather than copying them.

Chamber votes, 2022
Ministero dell’Interno — Eligendo
Votes for each list in the 25 September 2022 election, nationally and for each of the 27 constituencies, with turnout and electorate.
Held as the comparison baseline for election night 2027. Excludes Valle d’Aosta and the overseas constituency, which the ministry publishes separately, so totals are slightly below the official national figures.

Senate votes, 2022
Ministero dell’Interno — Eligendo
Votes for each list in the 25 September 2022 Senate election, region by region — the level at which the law shares out the proportional seats — plus the single-member seats of Valle d’Aosta and Trentino-Alto Adige, where there is no list vote.
List votes include, as the ministry counts them, those cast for the single-member candidate alone and attributed to the lists backing them. The 4 overseas seats are not in this archive: Eligendo publishes them only on its own HTML pages.

The Senate’s declared collegamenti, 2022
Ministero dell’Interno — Elezioni trasparenti
Which lists stood together at the Senate in 2022: the art. 14-bis declarations of collegamento, read from the ministry’s candidate files — 693 candidacies across the 74 single-member districts, each with the lists backing it. Two coalitions, four lists each.
A collegamento is declared once, nationally, but these files record it district by district — and in two German-speaking districts, Merano and Bressanone, the Partito Democratico and Alleanza Verdi e Sinistra ran alone. Four candidacies in all, listed in the data as `soloCandidacies`. The rule we apply is that a list belongs to the coalition it declared with wherever it declared one, and running alone somewhere does not dissolve it. That is a derivation rather than a field in the file, which is why the exception travels with the data instead of disappearing into it.

Deposited opinion polls
Presidenza del Consiglio dei ministri — Dipartimento per l’informazione e l’editoria
National voting-intention polls filed in the official register, with the pollster that ran it, who commissioned it, the fieldwork dates, the sample and the method.
The register is kept as a legal obligation (art. 8, l. 28/2000) and exposes no URL per poll, so we can only link to the list. Percentages appear as the pollster filed them, including coalition rows and non-party entries. In the 15 days before the vote this data is not published.

District boundaries
Geometry for all 221 single-member districts, composed from ISTAT’s published comune boundaries using the Interior Ministry’s comune-to-district mapping.
Six comuni are split between districts by quartiere. Each district’s composition comes from tables A.1 and B.1 of legislative decree 177/2020, and the quartiere boundaries from each comune’s own open data under its own licence: only Naples no longer publishes them, and it stays uncoloured. The district geometry still draws the whole comune, so twenty-five districts remain approximate until they are read quartiere by quartiere; every affected map says so.

Candidates at the 2027 election
Ministero dell’Interno — Elezioni trasparenti
The candidates in each district: the names in the single-member districts with the lists behind them, and the multi-member lists in the order they were filed.
It is empty, and will stay empty until roughly five weeks before the vote: lists are filed between the thirty-fifth and thirty-fourth day before polling day (art. 20, comma 1, d.P.R. 361/1957), and polling day is not yet fixed.
From the ministry’s file we take the name, the district, the list and the position on it — not the codice fiscale, not the date and place of birth, not the criminal-record certificate, all of which remain on the official register for the purpose they are published for.

Data is republished under its respective licences, which require attribution. We do not republish official documents: links always point to the original, and of the manifesto text we keep only what is needed to search inside them and to quote passages.
The tier says how close a source is to the original. Almost everything here is tier 1 or 2. Tier 3 covers the little that no official source publishes in open form — the mixed group’s components and the party of a deputy who won a single-member district — taken from a reputable third party and checked against the official data. Until 1 August 2026 it also covered the names of the deputies elected overseas, today’s parliamentary groups and who replaced whom: the Chamber opened its data and those moved to tier 1. The tier is given on every entry and repeated wherever the figure appears. Since 3 August 2026 tier 3 also covers the press review — twelve outlets of which we publish the headline, the date and the link, and nothing else. That is not a data source and cannot be checked against anything official: it is reading matter, and no figure on this site comes from it.
