The concept of a pool of employment is often used generically to define the area of influence of a particular economic cluster. It corresponds to a finer division of employment areas. Sometimes, an employment pool corresponds exactly to an area of employment.The exact determination methodology is not communicated by INSEE.The Melchior site gives this definition: INSEE has defined areas of employment, but the concept of employment basin (perimeter used by the Ministry of Labour) does not have a clear definition. Basins are subdivisions of employment areas and may constitute local policy frameworks for public authorities.就业池（employment pool）这一概念通常被泛用于界定特定产业集群的影响辐射范围，其对应就业区域的精细化划分。部分场景下，就业池可与就业区域完全重合。法国国家统计与经济研究所（INSEE）并未公开其精确的划定方法。梅尔基奥尔网站给出如下定义：INSEE已对就业区域作出明确界定，但就业流域（employment basin，即法国劳工部所采用的划定范围）尚无统一明确定义。就业流域是就业区域的次级划分单元，可作为公共管理机构制定地方政策的依托框架。
