本数据集收录了2006年人口普查日（8月8日，星期二）的通勤模式快照，采用自填式人口普查表完成全面枚举。

2006年通勤出行（Journey to Work, JTW）数据集的覆盖范围为：年龄满15周岁及以上、普查前一周处于在职状态且工作地点位于新南威尔士州（NSW）的就业人员。

由于以下原因，本JTW数据集的统计计数与澳大利亚统计局（Australian Bureau of Statistics, ABS）直接获取的同地理层级数据可能存在小幅差异：

* 交通绩效与分析部（Transport Performance and Analytics, TPA）采购的本数据集已应用澳大利亚统计局的保密处理流程（即对小样本单元格进行随机化处理）
* 交通绩效与分析部（TPA）对本数据集开展了进一步的验证与调整工作
* 对地址信息不完整的记录进行插补处理，以消除区域"垃圾编码"

本数据集使用的相关数据已获得澳大利亚统计局授权。
