Veteran Status 2020-2024 - STATES

This service contains the 2020-2024 release of data from the American Community Survey (ACS) 5-year data about Veteran Status, 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 percentage of the civilian population over the age of 18 that are Veterans. 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): DP02 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.本服务包含美国社区调查（American Community Survey, ACS）2020-2024年发布的5年期退伍军人身份相关数据，涵盖估算值与误差边际。此外还包含与该主题相关的额外计算属性，可用于制图或分析工作。该图层已设置符号化渲染，用于展示18岁以上平民人口中退伍军人的占比。若要查看本服务中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」。 当前数据版本：2020-2024年美国社区调查数据表（DP02） 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）：调查概况、地理信息与ACS技术文档、新闻与更新 该即用型图层可在ArcGIS Pro、ArcGIS Online、其可配置应用程序、仪表板、故事地图（Story Maps）、自定义应用程序以及移动应用中使用。数据也可导出用于离线工作流程。使用本数据时，请注明引用美国人口普查局与美国社区调查。 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。此处展示的为90%置信水平下的误差边际，其含义为：估算值减去误差边际与估算值加上误差边际所构成的区间（即置信上下限）有90%的概率包含真实数值。 除抽样变异性外，美国社区调查的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。边界数据与主题数据同步更新，且边界版本与美国人口普查局指定的数据版本完全匹配。 本数据集的普查边界已为制图目的裁剪掉水域及/或海岸线。对于州界与县界，其水域与海岸线源自50万比例尺TIGER制图边界形状文件的海岸线数据。 数据表格中仍保留原始的AWATER与ALAND字段作为属性（单位：平方米）。 州级图层共包含52条记录，涵盖全美所有州、华盛顿哥伦比亚特区以及波多黎各。 县级（及等效行政区）图层共包含3221条记录，涵盖全美所有县及等效行政区、华盛顿哥伦比亚特区以及波多黎各的自治市。 详见已发布区域说明。 占比与衍生计数及其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），且符合美国社区调查规定的计算规范。 字段别名均基于数据表壳（Table Shells）创建。 应用程序编程接口（API）中为-555555555的误差边际（Margin of Error, MOE）值（或data.census.gov网站上显示为「*****」的五个星号）在本数据集中将显示为0。 与这类误差边际对应的估算值已在美国社区调查的加权处理中校准至独立计数，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。 应用程序编程接口（API）中的其他负值，如-222222222、-666666666、-888888888与-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。本数据集将所有此类值渲染为空（null，即空白）值。
