The concept of urban unity is based on the continuity of the building and the number of inhabitants. An urban unit is a municipality or group of municipalities with a continuous built-up area (no cut-off of more than 200 metres between two buildings) with at least 2,000 inhabitants.If the urban unit is located in a single municipality, it is called an isolated city. If the urban unit extends over several municipalities, and each of these municipalities concentrates more than half of its population in the continuous built-up area, it is referred to as a multi-communal agglomeration.

城镇连片单元（urban unity）的概念以建筑连续性与居住人口规模为核心判定依据。城镇连片单元指拥有连续建成区（两栋建筑间间隔不超过200米）且居住人口不少于2000人的单个市镇或多个市镇的组合。若该城镇连片单元仅位于单个市镇范围内，则称其为独立城镇；若其跨越多个市镇，且每个相关市镇均有超过半数的人口聚集于连续建成区内，则称其为多市镇连片集聚区（multi-communal agglomeration）。
