Agglomerations

Agglomerations are concentrated settlements with at least 200 inhabitants. Statistics Sweden develops boundaries for urban areas using register data, such as Statistics Sweden's register of total population (RTB), Statistics Sweden's business register and Lantmäteriet's property map and coordinated building registers. Open geodata are displayed as polygons and up to 2015 urban areas have been updated every five years. Since 2016, they have been updated every three or two years.聚居集聚区（Agglomerations）指人口不少于200人的集中定居点。瑞典统计局（Statistics Sweden）依托各类登记数据划定城镇区域边界，所用数据源包括瑞典统计局总人口登记库（RTB）、商业登记库，以及瑞典土地测量局（Lantmäteriet）的地籍地图与协同建筑登记库。该数据集的公开地理数据以多边形（polygons）形式呈现；2015年及此前的城镇集聚区数据每五年更新一次，自2016年起，更新周期调整为每三年或每两年一次。
