It is a complete enumeration via a self-completion Census form.\n\n\nThe scope of JTW is employed persons aged 15 years and over, who were employed during the week before Census night, and with a workplace in NSW.\n\n\nJTW data may produce slightly different counts to those obtained directly from the Australian Bureau of Statistics (ABS) for the same geographic level due to:\n\n\n* ABS confidentialising process is applied to the data that TPA purchases (randomisation of small cells)\n* Further validation and adjustment of the data undertaken by TPA\n* Imputation of records of incomplete addresses to eliminate locality ‘dump’ codes\n\n\nABS data is used with permission from the Australian Bureau of Statistics\n\n\n

本数据集收录了2001年人口普查日（8月7日，星期二）的通勤模式快照，采用自主填报式人口普查表完成完整枚举。

本数据集（JTW）的统计范围为普查前夜当周处于就业状态、且工作地点位于新南威尔士州（NSW）的15岁及以上就业人群。

JTW数据集在同一地理层级下的统计计数，可能与澳大利亚统计局（Australian Bureau of Statistics, ABS）直接获取的同层级数据存在细微差异，具体原因如下：
* TPA所采购的数据已应用澳大利亚统计局的保密处理流程（对小单元格数据进行随机化处理）
* TPA对该数据集开展了进一步的校验与调整工作
* 对地址不完整的记录进行插补处理，以消除地域转储代码

本数据集使用的ABS数据已获得澳大利亚统计局的官方授权许可。
