List of electoral systems by country
Single-winner voting systems by nation
Multiple-winner voting systems by nation
Key:
- Seats per district - most elections are split into a number of districts (for example, a constituency). In some elections, there is one person elected per district. In others, there are many people elected per district.
- Total number of seats - the number of representatives elected to the body in total.
- Election threshold - see Election threshold
- FPTP - First-past-the-post electoral system
- Party list - One of many Party-list proportional representation systems. Where possible, this has been replaced by the allocation system used within the party-list (e.g. d'Hondt method)
- Parallel - This means that the country uses a party-list proportional representation system to elect some members and the specified other system to elect the rest. This differs from an additional member system because there is no attempt to have the party-list candidates make up for disproportionality in the other candidates listed.
Much of the data regarding which voting system is used is drawn from this 2002 report from the Institute for Democracy and Electoral Assistance.
Much of the data regarding the size of the parliaments comes from this 1997 report from the same Institute.
Some of the data has been updated since then.

Footnote
1 The Ceann Comhairle or Speaker of Dáil Éireann is returned automatically for whichever constituency s/he was elected if they wish to seek re-election, reducing the number of seats contested in that constituency by one. (In that case, should the Ceann Comhairle be from a three-seater, only two seats are contested in the general election from there.) As a result, if the Ceann Comhairle wishes to be in the next Dáil, only 165 seats are actually contested in a general election.
