Electoral system
Electoral rules place limits on suffrage and candidacy. Most countries's electorates are characterised by universal suffrage, but there are differences on the age at which people are allowed to vote, with the youngest being 16 and the oldest 21 (although voters must be 25 to vote in Senate elections in Italy). People may be disenfranchised for a range of reasons, such as being a serving prisoner, being declared bankrupt, having committed certain crimes or being a serving member of the armed forces. Similar limits are placed on candidacy (also known as passive suffrage), and in many cases the age limit for candidates is higher than the voting age. A total of 21 countries have compulsory voting, although in some there is an upper age limit on enforcement of the law. Many countries also have the none of the above option on their ballot papers.
Valencia (Corts Valencianes constituency)
Voting is on the basis of universal suffrage, which comprises all nationals over eighteen, registered in the Valencian Community and in full enjoyment of their political rights. Amendments to the electoral law in 2011 required for Valencians abroad to apply for voting before being permitted to vote, a system known as "begged" or expat vote (). Seats are elected using the D'Hondt method and a closed list proportional representation, with a threshold of 5 percent of valid votes—which includes blank ballots—being applied regionally. Parties not reaching the threshold are not taken into consideration for seat distribution.
