Inter-municipality commuting in Poland: Network analysis data and graphs

We analyze the pattern of regional labor mobility in Poland using inter-municipality commuting data. A simple static directed commuting network with 3,094 nodes and 34,986 edges is constructed. Data for the network have been taken from a comprehensive study of inter-municipality commuting conducted in 2016 by Statistics Poland (the link is provided in the data file). For aggregation, we chose to follow the official territorial units provided by Statistics Poland. The commuting database defines a connection between two municipalities if there are at least 10 commuters. We use the open-source software Gephi for network calculations and visualizations (force-directed and geo layouts). Our dataset includes PageRank (weighted), degree centrality, betweenness centrality, closeness centrality, HITS, and clustering coefficient.本研究依托波兰市镇间通勤数据，剖析波兰区域劳动力流动的格局与模式。我们构建了一个包含3094个节点、34986条边的简易静态有向通勤网络。该网络的数据集源自波兰中央统计局（Statistics Poland）2016年开展的市镇间通勤综合调查，数据文件中附有相关访问链接。在数据聚合环节，我们采用波兰中央统计局公布的官方行政区划单元作为统计基准。该通勤数据库设定判定规则：若任意两个市镇间的通勤人数不少于10人，则认定二者存在通勤关联。本研究使用开源软件Gephi开展网络计算与可视化工作，可视化方案涵盖力导向布局与地理布局两种类型。本数据集包含加权网页排名算法（PageRank）、度中心性（degree centrality）、介数中心性（betweenness centrality）、接近中心性（closeness centrality）、HITS（HITS）以及聚类系数（clustering coefficient）。
