ASGS SA3 2021 - Modified Monash Model 2023

Modified Monash Model (MMM)\r\n\r\nThe Modified Monash Model (MMM) is a classification system used to define the remoteness of Australian locations, ranging from MM 1 (major cities) to MM 7 (very remote areas). It combines population size and geographic remoteness to guide health workforce planning, especially in rural and remote communities. MMM is based on the Australian Statistical Geography Standard – Remoteness Areas (ASGS-RA) and is updated after each national Census conducted by the ABS.\r\n\r\nStatistical Area Level 3 (SA3)\r\n\r\nSA3s are regional areas used in the Australian Statistical Geography Standard (ASGS). Formed by grouping SA2s with similar characteristics, they provide a standard framework for analysing ABS data at the regional level, including Census outputs. Australia has 359 SA3s, including codes for non-geographically defined populations. SA3s are used to support regional planning and policy development, and they aggregate to form SA4s.

改良莫纳什模型（Modified Monash Model，MMM）

改良莫纳什模型是一套用于界定澳大利亚地区偏远程度的分类体系，分级范围覆盖MM 1（大城市）至MM 7（极偏远地区）。该体系结合人口规模与地理偏远程度两大维度，用于指导卫生人力规划工作，尤其面向农村及偏远社区。改良莫纳什模型以《澳大利亚统计地理标准——偏远区域》（Australian Statistical Geography Standard – Remoteness Areas，ASGS-RA）为基础，由澳大利亚统计局（Australian Bureau of Statistics，ABS）在每届全国人口普查完成后更新。

三级统计区域（Statistical Area Level 3，SA3）

三级统计区域是澳大利亚统计地理标准（Australian Statistical Geography Standard，ASGS）所采用的区域单元。其由特征相近的二级统计区域（Statistical Area Level 2，SA2）聚合而成，为区域层面的澳大利亚统计局数据（含人口普查产出数据）分析提供标准化框架。澳大利亚当前共设有359个三级统计区域，其中包含针对非地理界定人口的专属编码。三级统计区域可用于支撑区域规划与政策制定，其聚合后可形成四级统计区域（Statistical Area Level 4，SA4）。
