Croatian Parliament electoral districts

The Croatian Parliament electoral districts (izborne jedinice) are the special territorial subdivision of Croatia used for the country's parliamentary elections.

Croatia has twelve electoral districts. Ten of these are geographical districts within Croatia, each providing fourteen members of Croatian Parliament. District XI is for Croatian citizens living abroad, with three members of parliament (until 2011, it elected a maximum twelve members of parliament, depending on turnout). District XII is for national minorities, providing eight members of parliament.

The first ten districts are roughly based on geography, but shaped according to the number of voters so that each district holds roughly the same amount of registered voters, around 400,000. These districts therefore do not correspond to the borders of top administrative divisions within Croatia and each district contains one or more or parts of several Croatian counties.

History
These districts have been in place since the Law on Electoral Districts of 1999.

They have been used in the following elections : 2000, 2003, 2007, 2011, 2015, 2016, 2020.

In December 2010, the Constitutional Court of Croatia ruled that an update to the layout of electoral districts was necessary, as the differences in the number of voters among the districts, limited by law to 5%, had grown to 25%.

The first proposal to amend the election law was proposed by Dragutin Lesar, from the Croatian Labourists – Labour Party, in 2011. The new law proposed a division into six geographical constituencies with fixed borders based on county borders, and the number of seats would depend on the number of voters in each. In the first elections, the units would have between 20 and 25 seats. The law also proposed retaining units for the diaspora and national minorities. The proposal was eventually withdrawn due to lack of support.

The second proposal followed in 2014, when the Croatian Labourists – Labour Party proposed constructively the same law with updated mandate numbers, according to which the units had between 20 and 26 mandates. The proposal passed the first vote but fell in the form of a final bill.

The third proposal was discussed at the same time as the second, and was proposed by the Istrian Democratic Assembly. These changes were accompanied by previous laws according to which the boundaries of constituencies should be adjusted to the number of voters, which would reduce the difference in number of voters below 2%. The proposal passed the first vote, but no final debate was held so it was not adopted.

The fourth proposal for changes to the law came from the referendum initiative "People Decide" ("Narod odlučuje"), which in 2018 collected signatures for calling a referendum. The initiative advocated reducing the number of deputies to 100 to 120, with each constituency electing at least 15 deputies, and reducing the number of constituencies whose borders would coincide with those of counties in the future. The Ministry of Administration found that the initiative did not collect enough signatures, which is why a referendum did not follow.

The fifth proposal came from the Social Democratic Party of Croatia, which, along with the amendment of the Law on Electoral Units, also proposes the amendment of the Law on the Election of Members of the Croatian Parliament. The changes envisage six constituencies with the number of mandates depending on the population in each of them, and the current change would be from 18 to 29 representatives.

On February 7, 2023, the Constitutional Court issued a decision repealing the Law on Electoral Units, which expires on October 1, 2023. This required Parliament to pass a new law that would meet legal standards.

On May 25, the government proposed a new law on constituencies, changing only the boundaries of the existing ones to achieve a deviation of less than 5%.

On September 28, 2023, the Croatian Parliament passed the law, but due to it not being signed by the President before October 1, 2023, the law had to be passed a second time on October 20, 2023 and came into effect on November 3, 2023.

Difference between districts
The difference represents the total difference between the largest and smallest district during each election. The legal difference is not above 5%.
