Airdrie South is one of the twenty-one wards used to elect members of the North Lanarkshire Council.[2] It elects four councillors, with its territory unaffected by a national boundary review in 2017 – as its name suggests, this covers southern parts of Airdrie (including Brownsburn, Craigneuk, Moffat Mills, Petersburn and South Cairnhill neighbourhoods) plus the outlying settlements of Calderbank and Chapelhall, covering a population of 19,934 in 2019.[3]
