# Australian Geographic Insights: Boundaries and Statistics Geography - Boundaries & Insights - Australia data listing includes data sets from several Australian organisations that have made their data freely available under Creative Commons licencing. The following details the data providers and their data sets. ## Australian Bureau of Statistics (ABS) The Australian Statistical Geography Standard (ASGS) is a classification of Australia into a hierarchy of statistical areas. It is a social geography, developed to reflect the location of people and communities. It is used for the publication and analysis of official statistics and other data. The ASGS is updated every 5 years to account for growth and change in Australia’s population, economy and infrastructure. ASGS Edition 3 was used for the 2021 Census of Population and Housing, and will be progressively introduced into other ABS data collections from 2022. ASGS Edition 3 is an update of ASGS Edition 2 (2016). Mesh Blocks (MBs) are the smallest geographic areas defined by the ABS and form the building blocks for the larger regions of the ASGS. Most Mesh Blocks contain 30 to 60 dwellings. Statistical Areas Level 1 (SA1s) are designed to maximise the geographic detail available for Census of Population and Housing data while maintaining confidentiality. Most SA1s have a population of between 200 to 800 people. Statistical Areas Level 2 (SA2s) are medium-sized general purpose areas built to represent communities that interact together socially and economically. Most SA2s have a population range of 3,000 to 25,000 people. Statistical Areas Level 3 (SA3s) are designed for the output of regional data and most have populations between 30,000 and 130,000 people. Statistical Areas Level 4 (SA4s) are designed for the output of a variety of regional data, and represent labour markets and the functional area of Australian capital cities. Most SA4s have a population of over 100,000 people. **Schemas available:** - GEOGRAPHY_AUS_FREE contains the Australian Bureau of Statistic's ASGS data for both GDA94 and GDA2020 datums **Tables available:** - ABS_MB_2021_AUST_GDA94: - ABS_SA1_2021_AUST_GDA94: - ABS_SA2_2021_AUST_GDA94: - ABS_SA3_2021_AUST_GDA94: - ABS_SA4_2021_AUST_GDA94: - ABS_MB_2021_AUST_GDA2020: - ABS_SA1_2021_AUST_GDA2020: - ABS_SA2_2021_AUST_GDA2020: - ABS_SA3_2021_AUST_GDA2020: - ABS_SA4_2021_AUST_GDA2020: Each table contains: - GEOMETRY - the datum is part of the table name - GCCSA_CODE_2021 - Greater Capital City Statistical Area Code - GCCSA_NAME_2021 - Greater Capital City Statistical Area Name - STATE_CODE_2021 - STATE_NAME_2021 - the code hierarchy for geography Nomenclature<br/>Table names have the format <data type>*<2021>*<AUST>_<GDA> where: <data type> represents the type of boundaries in each table<br/>MB = Mesh Block<br/>SA1 = Statistical Area Level 1<br/>SA2 = Statistical Area Level 2<br/>SA3 = Statistical Area Level 3<br/>SA4 = Statistical Area Level 4<br/>GCCSA = Greater Capital City Statistical Area<br/>STE = State and Territory<br/>AUS = Australia<br/><2021> represents 2021 the year of the Australian Statistical Geography Standard (ASGS) Edition 3<br/><AUST> indicates the data covers all of Australia<br/><GDA> indicates the Geocentric Datum of Australia used, and may equal GDA94 or GDA2020
# 澳大利亚地理洞察：边界与统计数据 本澳大利亚地理-边界与洞察类数据列表收录了多家澳大利亚机构发布的、基于知识共享（Creative Commons）许可协议免费公开的数据集。 以下详述各数据提供商及其对应数据集。 ## 澳大利亚统计局（ABS） 澳大利亚统计地理标准（Australian Statistical Geography Standard, ASGS）是将澳大利亚划分为层级统计区域的分类体系，属于人文地理范畴，旨在精准反映人口与社区的空间分布，主要用于官方统计数据及其他相关数据的发布与分析。ASGS每5年更新一次，以适配澳大利亚人口、经济与基础设施的发展变化。 ASGS第3版已应用于2021年全国人口与住房普查，并将于2022年起逐步推广至ABS的其他数据采集工作中，其为ASGS第2版（2016年版）的更新迭代版本。 统计网格单元（Mesh Blocks, MBs）是ABS定义的最小地理区域，为ASGS更高层级区域的构成基础，多数统计网格单元包含30至60处住宅。 统计区域1级（Statistical Areas Level 1, SA1s）旨在最大化保留人口与住房普查数据的地理细节，同时保障数据匿名性，多数统计区域1级的人口规模介于200至800人之间。 统计区域2级（Statistical Areas Level 2, SA2s）是中等规模的通用地理区域，用于代表社会与经济互动紧密的社区，多数统计区域2级的人口规模介于3000至25000人之间。 统计区域3级（Statistical Areas Level 3, SA3s）用于输出区域级数据，多数统计区域3级的人口规模介于30000至130000人之间。 统计区域4级（Statistical Areas Level 4, SA4s）用于输出多类区域级数据，代表劳动力市场及澳大利亚首府城市的功能区域，多数统计区域4级的人口规模超过100000人。 **可用架构：** - GEOGRAPHY_AUS_FREE：包含澳大利亚统计局（ABS）的ASGS数据，涵盖GDA94与GDA2020两种大地基准面 **可用数据表：** - ABS_MB_2021_AUST_GDA94： - ABS_SA1_2021_AUST_GDA94： - ABS_SA2_2021_AUST_GDA94： - ABS_SA3_2021_AUST_GDA94： - ABS_SA4_2021_AUST_GDA94： - ABS_MB_2021_AUST_GDA2020： - ABS_SA1_2021_AUST_GDA2020： - ABS_SA2_2021_AUST_GDA2020： - ABS_SA3_2021_AUST_GDA2020： - ABS_SA4_2021_AUST_GDA2020： 每个数据表包含以下字段： - GEOMETRY：大地基准面信息已包含在数据表名称中 - GCCSA_CODE_2021：首府城市统计区域（Greater Capital City Statistical Area, GCCSA）代码（2021版） - GCCSA_NAME_2021：首府城市统计区域名称（2021版） - STATE_CODE_2021：州/领地代码（2021版） - STATE_NAME_2021：州/领地名称（2021版） - 地理层级编码体系 **命名规范**<br/>数据表名称格式为`<数据类型>*<2021>*<AUST>_<GDA>`，其中： `<数据类型>`代表数据表中的边界类型： MB = 统计网格单元（Mesh Block） SA1 = 统计区域1级（Statistical Area Level 1） SA2 = 统计区域2级（Statistical Area Level 2） SA3 = 统计区域3级（Statistical Area Level 3） SA4 = 统计区域4级（Statistical Area Level 4） GCCSA = 首府城市统计区域（Greater Capital City Statistical Area） STE = 州与领地（State and Territory） AUS = 澳大利亚 `<2021>`代表澳大利亚统计地理标准（ASGS）第3版的对应年份2021年 `<AUST>`表示数据覆盖澳大利亚全境 `<GDA>`代表所采用的澳大利亚大地基准面（Geocentric Datum of Australia），可选值为GDA94或GDA2020
