Key

Seats per district 
Most elections are split into a number of electoral districts. In some elections, there is one person elected per district. In others, there are many people elected per district. Electoral districts can have different names, see list of electoral districts by nation.
Total number of seats 
the number of representatives elected to the body in total.
Election threshold 
see Election threshold
FPTP 
Using the system of First Past The Post voting to pick a single winner per district
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 Where possible, this has been replaced by the allocation system used within the party-list (e.g. D'Hondt method)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 (e.g. the number elected in one system affects the number elected in the other) then this is called the additional member system.

Notes

  1. ↑ For a round to be declared valid, the turnout must be at least 50% of voters in the electoral register.
  2. ↑ For the first round of elections to be declared valid, at least 50% of voters in the electoral register must have voted. For the runoff round between the top two candidates, the requirement is 25%.
  3. ↑ 3.0 3.1 Louisiana uses a variant of the blanket primary with the primary at the day of the general election, with a runoff if no candidate receives a majority, while California and Washington has a primary before the general election with the top-two candidates facing off in the general election regardless of whether one has a majority or not. Many states use runoff voting in the partisan primaries.
  4. ↑ 4.0 4.1 Elections in the united states commonly feature partisan primary elections run by the state (as opposed to by the parties), see Primary election#Primaries in the United States
  5. ↑ The constitution specifies the extra 60 seats for women only for the two first parliaments. The first parliament elected with this constitution was in 2013[50]

Independent candidates need to gather votes equal to the total number of votes cast in the constituency divided by the number of local seats. The remaining seats are distributed among parties by the D'Hondt method applied to the total number of votes for each. Party lists are one per constituency, the seats each party wins are further distributed among its local lists again by D'Hondt applied to local numbers of votes for the party, and a mechanism of shifting seats from one local Party list to another, to adjust the total seats for all parties for each constituency to the allocated local number of seats (minus the number of successful local independent candidates).

(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.

Much of the data on Bulgaria from Central electoral committee - "Methods for determining the number of mandates in constituencies and the results of the vote" (in Bulgarian); A mathematical analysis of the system

Much of the data regarding which voting system is used is drawn from this 2002 report from the International Insititute for Democracy and Electoral Assistance (IDEA).

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.
