OnTheMap所使用的LEHD职住起讫就业统计数据（LEHD Origin-Destination Employment Statistics, LODES）可通过以下途径下载。LODES第7版以2010年人口普查街区为统计单元编制，此前各版LODES均采用2000年人口普查街区作为统计单元。
数据文件以州为单位组织，共分为三类：职住起讫（Origin-Destination, OD）数据、居住区域特征（Residence Area Characteristics, RAC）数据以及工作区域特征（Workplace Area Characteristics, WAC）数据，所有数据均采用人口普查街区级地理粒度。2002至2013年的该数据覆盖美国大部分州。
