Boundaries of Tertiary Planning Units & Street Blocks / Village Clusters (for 2011 Population Census)

Tertiary Planning Unit and Street Block/Village Cluster Boundaries Adopted in 2011 Population Census

For town planning purpose, the whole territory of Hong Kong is divided into 289 Tertiary Planning Units (TPUs) in the 2011 Population Census. On the one hand, these TPUs are sub-divided into Street Blocks (SBs) or Village Clusters (VCs) in urban and rural areas respectively. On the other hand, these TPUs are aggregated under 52 Secondary Planning Units (SPUs) at the next higher level. The SPUs are further grouped under nine Primary Planning Units (PPUs) at the highest level. Each of the TPU is identified by a unique three-digit number. The first digit of a TPU number identifies the PPU code while the first and second digits together correspond to the SPU code.

In translating the boundaries of TPUs and SBs/VCs for 2011 Population Census to digital format, reference has been made to different topographic maps, which may of various scales, prepared by Survey and Mapping Office, Lands Department available at the time of preparation. Since the geographical features on these maps may be updated from time to time, the boundaries of TPUs and SBs/VCs may not tally with the latest situation. Users are responsible for making their own assessment of the obtained data and are advised to verify such information before acting on it.

2011年人口普查采用的三级规划单元及街区/村落集群边界

为适配城镇规划需求，香港全域在2011年人口普查中被划分为289个三级规划单元（Tertiary Planning Units, TPUs）。其中，市区的三级规划单元进一步细分为街区（Street Blocks, SBs），郊区的三级规划单元则划分为村落集群（Village Clusters, VCs）；同时，上述三级规划单元可向上聚合为52个二级规划单元（Secondary Planning Units, SPUs），而二级规划单元又可进一步归为9个最高层级的一级规划单元（Primary Planning Units, PPUs）。每个三级规划单元均由唯一的三位数字标识，其编号的第一位数字对应一级规划单元代码，前两位数字则对应二级规划单元代码。

本次将2011年人口普查的三级规划单元及街区/村落集群边界转换为数字化格式时，参考了编制本数据集时任由地政总署测绘处（Survey and Mapping Office, Lands Department）制作的多比例尺地形图图件。由于上述地图所载的地理信息可能随时间更新，三级规划单元及街区/村落集群的边界或与当前最新实际情况存在偏差。使用者需自行评估所获取数据的适用性，且建议在基于该信息开展相关操作前先行核实相关内容。
