### Seat projections

Because the seats in the Parliament are split according to Croatian Parliament electoral districts, seat projections significantly vary from a generic overall poll.
The seat projections do not include:
* the 8 seats from minority voters, and these representatives are not usually strictly aligned with mainstream parties
* the 3 seats from voters residing abroad, which have in every election since independence gone to HDZ
The new composition of Parliament will have 151 seats meaning that 76 seats will be needed for a majority.
Because of the nature of the D'Hondt method and the division into constituencies, seat projections are less reliable, so some polls list tentative options, indicated in parentheses.
The listed poll dates are either the dates when the poll was conducted, or alternatively the date when the poll result was published.
