Worked at Home 2020-2024 - COUNTIES

This layer shows Commuting to Work. This is shown by state and county boundaries. This service contains the most currently released American Community Survey (ACS) 5-year data, and contains estimates and margins of error. There are also additional calculated attributes related to this topic, which can be mapped or used within analysis. This layer is symbolized to show Population that worked at home. To see the full list of attributes available in this service, go to the "Data" tab, and choose "Fields" at the top right. Current Vintage: 2020-2024 ACS Table(s): DP03 Data downloaded from: Census Bureau's API for American Community Survey Date of API call: March 3, 2026 National Figures: data.census.gov The United States Census Bureau's American Community Survey (ACS): About the Survey Geography & ACS Technical Documentation News & Updates This ready-to-use layer can be used within ArcGIS Pro, ArcGIS Online, its configurable apps, dashboards, Story Maps, custom apps, and mobile apps. Data can also be exported for offline workflows. Please cite the Census and ACS when using this data. Data Note from the Census: Data are based on a sample and are subject to sampling variability. The degree of uncertainty for an estimate arising from sampling variability is represented through the use of a margin of error. The value shown here is the 90 percent margin of error. The margin of error can be interpreted as providing a 90 percent probability that the interval defined by the estimate minus the margin of error and the estimate plus the margin of error (the lower and upper confidence bounds) contains the true value. In addition to sampling variability, the ACS estimates are subject to nonsampling error (for a discussion of nonsampling variability, see Accuracy of the Data). The effect of nonsampling error is not represented in these tables. Data Processing Notes: Boundaries come from the Cartographic Boundaries via US Census TIGER geodatabases. Boundaries are updated at the same time as the data updates, and the boundary vintage appropriately matches the data vintage as specified by the Census. These are Census boundaries with water and/or coastlines clipped for cartographic purposes. For state and county boundaries, the water and coastlines are derived from the coastlines of the 500k TIGER Cartographic Boundary Shapefiles. The original AWATER and ALAND fields are still available as attributes within the data table (units are square meters). The States layer contains 52 records - all US states, Washington D.C., and Puerto Rico. The Counties (and equivalent) layer contains 3221 records - all counties and equivalent, Washington D.C., and Puerto Rico municipios. See Areas Published. Percentages and derived counts, and associated margins of error, are calculated values (that can be identified by the "_calc_" stub in the field name), and abide by the specifications defined by the American Community Survey. Field alias names were created based on the Table Shells. Margin of error (MOE) values of -555555555 in the API (or "*****" (five asterisks) on data.census.gov) are displayed as 0 in this dataset. The estimates associated with these MOEs have been controlled to independent counts in the ACS weighting and have zero sampling error. So, the MOEs are effectively zeroes, and are treated as zeroes in MOE calculations. Other negative values on the API, such as -222222222, -666666666, -888888888, and -999999999, all represent estimates or MOEs that can't be calculated or can't be published, usually due to small sample sizes. All of these are rendered in this dataset as null (blank) values.本图层用于呈现通勤上班相关数据，以美国州界与县界作为地理边界载体。本服务采用当前最新发布的美国社区调查（American Community Survey, ACS）5年周期数据，包含统计估算值与误差边际（Margin of Error, MOE）。此外还包含与该主题相关的衍生计算属性，可用于制图或分析工作。 本图层的符号系统用于展示居家办公人口分布。如需查看本服务中所有可用属性的完整列表，请前往「数据」选项卡，并点击右上角的「字段」选项。 当前数据版本：2020-2024年ACS数据表DP03 数据来源：美国人口普查局美国社区调查应用程序编程接口（API） API调用日期：2026年3月3日 全国统计数据来源：data.census.gov 美国人口普查局美国社区调查（ACS）相关内容：调查概况、地理数据规范、ACS技术文档及最新资讯 本图层为即开即用型，可在ArcGIS Pro、ArcGIS Online、其可配置应用程序、仪表盘、Story Maps、自定义应用程序及移动应用中使用。数据也可导出以支持离线作业。使用本数据时，请注明引用美国人口普查局与ACS。 美国人口普查局数据说明：本数据基于抽样调查，存在抽样变异性。由抽样变异性导致的估算值不确定程度通过误差边际体现。本数据集展示的误差边际为90%置信水平下的结果，即该误差边际可理解为：估算值加减误差边际所形成的区间（置信上下限）包含真实值的概率为90%。 除抽样变异性外，ACS估算值还存在非抽样误差（关于非抽样变异性的讨论，请参见《数据精度》文档）。本数据表未体现非抽样误差的影响。 数据处理说明： 边界数据源自美国人口普查局TIGER地理数据库中的制图边界。边界数据与统计数据同步更新，且边界数据版本与人口普查局规定的统计数据版本完全匹配。本数据集采用的普查边界已为制图需求裁剪掉水域及海岸线内容。针对州界与县界，其水域及海岸线数据源自50万比例尺TIGER制图边界形状文件的海岸线图层。原始的AWATER和ALAND字段仍作为属性保留在数据表中（单位：平方米）。 州图层共包含52条记录，涵盖美国所有州、华盛顿哥伦比亚特区及波多黎各。 县（及等效行政单元）图层共包含3221条记录，涵盖美国所有县及等效行政单元、华盛顿哥伦比亚特区以及波多黎各的自治区。 详见已发布的区域范围说明。 百分比、衍生计数及对应的误差边际均为计算所得值（可通过字段名中的「_calc_」标识识别），且严格遵循ACS制定的计算规范。字段别名均基于数据表框架（Table Shells）创建。 API中取值为-555555555的误差边际值（或data.census.gov网站上显示为「*****」的内容）在本数据集中将显示为0。与这类误差边际对应的估算值在ACS加权过程中已被校准至独立统计值，不存在抽样误差，因此此类误差边际实际为0，并在误差边际计算中按0处理。 API中其他负值（如-222222222、-666666666、-888888888及-999999999）均代表因样本量过小等原因无法计算或发布的估算值或误差边际，此类值在本数据集中均以空值（null，即空白）展示。
