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 Where possible, this has been replaced by the allocation system used within the party-list (e.g. d'Hondt method)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 voting - This means that two simultaneous systems are used to elect representatives to the same body. If there is interchange between the two systems, this is called (e.g. the number elected in one system affects the number elected in the other), then this is the additional member system.

Much of the data regarding which voting system is used is drawn from from the Institute for Democracy and Electoral Assistance.

Much of the data regarding the size of the parliaments comes from 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.
