Housing Tenure 2020-2024 - STATES

This layer shows Housing Tenure. This is shown by state and county boundaries. This service contains the 2020-2024 release of data from the 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 the predominant housing type: owner-occupied, renter-occupied, or other. The size of the symbol represents the total count of housing units. 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): B25010, DP04 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.本图层展示住房保有状况（Housing Tenure），以州界与县界作为地理分区范围。本服务采用美国社区调查（American Community Survey, ACS）5年周期数据的2020-2024版数据集，包含统计估计值与误差边际。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。本图层通过符号化展示主要住房类型：自有住房（owner-occupied）、租赁住房（renter-occupied）及其他类型。符号大小代表住房总单元数。如需查看本服务可用属性的完整列表，请进入「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B25010、DP04 数据下载来源：美国人口普查局美国社区调查API API调用日期：2026年3月3日 全国统计数据：data.census.gov 美国人口普查局美国社区调查（ACS）：关于调查、地理信息与ACS技术文档、最新动态 本图层为可直接使用的数据集，可在ArcGIS Pro、ArcGIS Online、其可配置应用、仪表盘、故事地图（Story Maps）、自定义应用及移动应用中调用。数据亦可导出用于离线作业流程。使用本数据时，请注明引用美国人口普查局与ACS。 数据说明： 本数据基于抽样调查，存在抽样变异性。抽样变异性带来的估计值不确定程度通过误差边际（Margin of Error, MOE）体现。本数据集展示的误差边际为90%置信水平下的数值，其含义为：估计值加减误差边际所形成的区间（即置信上下限）有90%的概率包含真实数值。除抽样变异性外，ACS估计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），但本数据表未体现非抽样误差的影响。 数据处理说明： 地理边界源自美国人口普查局TIGER地理数据库的制图边界文件。边界更新频率与数据更新周期一致，且边界版本与人口普查局指定的数据版本完全匹配。为满足制图需求，本图层已对州、县界中的水域及海岸线进行裁剪处理，水域海岸线数据源自500k分辨率TIGER制图边界形状文件的海岸线图层。原始AWATER和ALAND字段仍作为属性保留在数据表中，单位为平方米。 州级图层共包含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及波多黎各的自治区。详见《发布区域》文档。 百分比与衍生计数及其对应的误差边际均为计算值（字段名称中带有「_calc_」前缀即可识别），且严格遵循ACS的相关规范。字段别名均基于数据表壳（Table Shells）生成。 API中返回的误差边际（MOE）值-555555555（或data.census.gov网站上显示的「*****」五个星号）在本数据集中将被显示为0。与这些误差边际对应的估计值已在ACS加权流程中被校正为独立统计量，抽样误差为0，因此其误差边际实际为0，本数据集将此类误差边际按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计值或误差边际，本数据集将此类数值统一显示为空值（null，即空白）。
