Electoral districts of South Australia

{{Short description|Electorate for the South Australian House of Assembly}}

{{Use dmy dates|date=April 2022}}

Since 1970, the South Australian House of Assembly — the lower house of the Parliament of South Australia — has consisted of 47 single-member electoral districts consisting of approximately the same number of enrolled voters. The district boundaries are regulated by the State Electoral Office, according to the requirements of the South Australian Constitution and are subject to mandatory redistributions by the South Australian Electoral Districts Boundaries Commission in order to respond to changing demographics.

Boundary adjustments

Electoral boundaries are adjusted after each election. The number of electors in each district must be within 10% of the average at the time of the redistribution order. Other issues that may be considered include economic, social and regional communities of interest.{{cite web|title=Electoral Questions & Answers |url=http://seo.sa.gov.au/apps/uploadedFiles/news/276/SEO_QA06_13feb06.pdf |format=PDF, page 11 |publisher=State Electoral Office, South Australia |access-date=2006-11-08 |url-status=dead |archive-url=https://web.archive.org/web/20060821050558/http://www.seo.sa.gov.au/apps/uploadedFiles/news/276/SEO_QA06_13feb06.pdf |archive-date=2006-08-21 }} From 1990 to 2018, it was also a requirement that each redistribution attempt to ensure that the party that obtains 50% or more of the overall vote at a general election would be able to form a government; this requirement has since been repealed.

While South Australia's total population exceeds 1.8 million, Adelaide's population exceeds 1.4 million (as at 30 June 2023) {{cite web | url=https://www.abs.gov.au/statistics/people/population/national-state-and-territory-population/latest-release | title=National, state and territory population, December 2023 | Australian Bureau of Statistics | date=13 June 2024 }} − uniquely highly centralised, over 78% of the state's population resides in the Greater Adelaide metropolitan area and has 72% of seats (34 of 47) alongside a lack of comparatively sized rural population centres, therefore the metropolitan area is crucial in deciding election outcomes. At the 2014 election for example, although the statewide two-party vote (2PP) was 47.0% Labor vs. 53.0% Liberal, the metropolitan area recorded a 2PP of 51.5% Labor v 48.5% Liberal.{{ref|a|a}}
