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 building 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 referred to as 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.

城市连片区域（urban unity）的概念以建筑连续性与居民人口规模为判定依据。城市单元（urban unit）指具备连续建成区（两栋建筑间距不超过200米）且常住人口不少于2000人的单个市镇或市镇集群。若该城市单元仅隶属于单个市镇，则称为孤立城市；若其跨越多个市镇，且各相关市镇均有过半人口集中于该连续建成区内，则称为多市镇集聚区（multi-communal agglomeration）。
