Each multi-member district leads to its own page, where the single-member districts inside it are in turn selectable on a map. Here the map shows where the districts are, not how they voted.

Eight single-member districts belong to no multi-member one: Valle d’Aosta in both chambers and the six Trentino-Alto Adige/Südtirol Senate districts elect in the single-member college only. They are on the map, and they lead straight to the district’s own page. The three Lazio 1 multi-member districts divide the comune of Roma between them: the map draws them municipio by municipio, from the boundaries Roma Capitale publishes.

Single-member districts are three eighths of the seats elected in the domestic constituencies, with the other five eighths filled in multi-member districts. The rounding, though, is not the same in the two chambers: in the Chamber those seats number 392 and the rounding is down, so three eighths of 392 is exactly 147; in the Senate they number 196, the rounding is to the nearest whole number and every constituency gets at least one district, so three eighths of 196 is 73.5, and becomes 74.

How many votes a single-member seat cost

Valid list votes in the Chamber election of 25 September 2022, divided by the number of single-member districts in the constituency. 27 of 28 constituencies.

A single-member deputy cost 244,453 votes in Basilicata and 126,371 in Trentino-Alto Adige/Südtirol — 1.9 times as many to elect one person. Districts are drawn on resident population rather than on voters, and the number of districts each constituency gets starts from a minimum fixed in law.

The dashed line is the mean across the constituencies shown: 191,401 votes per district.

This counts the 147 single-member districts, not the Chamber’s other 253 seats. The numerator is votes cast, not electors: where fewer people vote, a seat costs fewer votes.

Not in the chart: Valle d’Aosta, which the ministry publishes in a file of its own, and the overseas constituency, which has no single-member districts.

How many votes a single-member seat cost

Valid list votes in the Senate election of 25 September 2022, divided by the number of single-member districts in the region. 18 of 20 regions.

A single-member senator cost 624,557 votes in Abruzzo and 129,686 in Molise — 4.8 times as many to elect one person. Districts are drawn on resident population rather than on voters, and every region gets at least one seat however few people live in it.

The dashed line is the mean across the regions shown: 403,152 votes per district.

This counts 67 of the Senate’s 74 single-member districts, not its 122 proportional seats. The numerator is votes cast, not electors: where fewer people vote, a seat costs fewer votes.

Not in the chart: Valle d'Aosta and Trentino-Alto Adige/Südtirol, which elect 7 senators in as many single-member districts with no list vote at all — nobody there votes for a list, so the numerator does not exist. Nor are the 4 overseas seats, which sit inside no region and have no single-member districts.
