From 2012, Community Centres/Clubs was renamed as Community Centres (void decks) to better refer to the community centres that are built by HDB which are located in HDB void decks.
Data for Area Offices, Branch Offices and Town Council Offices was revised in 2013 and area offices were taken out as they have been incorporated under commercial properties. Admin offices which are located in Neighbourhood Centres were included instead. Hence, the data from 2013 was renamed to Admin Offices, Branch Offices and Town Council Offices.
