Lists key to understanding how electoral system operates
THE 24 seats in the geographical elections will be returned according to the percentage of votes secured by each campaign ticket.
Parties rank candidates on the tickets, who will then be elected in the constituencies according to the ranking.
Non-affiliated hopefuls may also form their own tickets or run on a one-person ticket.
A voter will put a tick beside his or her preferred ticket, rather than a particular candidate.
Under the largest-remainder formula, the chances of winning a seat will be based on a 'quota' obtained by dividing the number of votes by the number of seats in the constituency.
If, for instance, the five-seat Hong Kong Island constituency has 300,000 votes, the top candidate on any ticket that secures one-fifth - 60,000 - of the votes will win a seat.
