The new District Councils will consist of a total of 470 members.
There will be 88 directly-elected seats across 44 geographical constituencies. A total of 171 candidates are running, meaning an average of about four candidates are taking part in each race.
176 councillors will be picked by government-appointed members of three local bodies – the area, fire safety and fight crime committees. 228 candidates are vying for these seats in the district committees constituencies.
The government will also appoint 179 councillors, while the remaining 27 are ex-officio members.
The DAB and the Federation of Trade Unions are fielding the highest number of candidates in the geographical and district committees constituencies, while some hopefuls are declaring themselves as independent or non-politically affiliated.
On election day, polling stations across Hong Kong will open from 8.30am to 10.30pm. Hongkongers on the mainland can vote at one of the two designated polling stations in Sheung Shui.
Also from 8.30am, there'll be a six-hour window for those selecting members of the district committees constituencies.
