Saint-Amandois Basin of Life

Base of the constituent municipalities of the Saint-Amandois basin of life 2012 to 1 January 2022 The living area is the smallest area in which people have access to the most common facilities and services. Its contours are defined in several stages. First, a service centre is defined as a municipality or urban unit with at least 16 of the 31 intermediate facilities. The zones of influence of each service pole are then delimited by grouping the nearest municipalities, the proximity being measured in travel time, by road at off-peak time. Thus, for each municipality and for each piece of equipment not present in the municipality, the nearest municipality offering this equipment is determined. Intermediate equipment but also local equipment are taken into account. The ANABEL method finally makes it possible to aggregate municipalities by successive iterations and to draw the **perimeter of living areas as the smallest territory on which inhabitants have access to the most common facilities and services**. Zoning into living areas complements this by analysing the distribution of equipment and access to it. Its main interest is to describe unpopulated areas, i.e. living areas built on urban units with fewer than 50 000 inhabitants.” (source: INSEE)2012年至2022年1月1日圣阿芒多瓦生活流域（Saint-Amandois basin of life）的组成市镇基础数据集 生活片区（living area）指居民可获取最常见公共设施与服务的最小空间范围。其边界划定分为多个阶段：首先将具备31项中间设施中至少16项的市镇或城市单元定义为服务中心；随后以非高峰时段的道路通行时长衡量邻近程度，通过聚合邻近市镇划定各服务极的影响范围；针对每个市镇及其未覆盖的各类设施，匹配提供该设施的最近市镇。本次划定同时涵盖中间设施与本地设施。 最终，ANABEL方法可通过多轮迭代完成市镇聚合，并划定**生活片区边界——即居民可获取最常见公共设施与服务的最小地域范围**。生活片区区划通过分析设施分布与可达性，对上述划定框架进行补充完善。 该数据集的核心价值在于刻画无人居住区域，即依托人口不足5万的城市单元形成的生活片区。（数据来源：法国国家统计与经济研究所（INSEE））
