Hispanic/Latino Predominance - Other Hispanic-Latino
收藏资源简介:
This layer shows Hispanic or Latino origin by specific origin. This is shown by tract, county, and state boundaries. This service is updated annually to contain 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 the percentage of the population with Hispanic or Latino origins. 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: 2016-2020 ACS Table(s): B03001 Data downloaded from: Census Bureau's API for American Community Survey Date of API call: March 17, 2022 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. For more information about ACS layers, visit the FAQ. 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: This layer is updated automatically when the most current vintage of ACS data is released each year, usually in December. The layer always contains the latest available ACS 5-year estimates. It is updated annually within days of the Census Bureau's release schedule. Click here to learn more about ACS data releases. Boundaries come from the US Census TIGER geodatabases, specifically, the National Sub-State Geography Database (named tlgdb_(year)_a_us_substategeo.gdb). Boundaries are updated at the same time as the data updates (annually), and the boundary vintage appropriately matches the data vintage as specified by the Census. These are Census boundaries with water and/or coastlines erased for cartographic and mapping purposes. For census tracts, the water cutouts are derived from a subset of the 2020 Areal Hydrography boundaries offered by TIGER. Water bodies and rivers which are 50 million square meters or larger (mid to large sized water bodies) are erased from the tract level boundaries, as well as additional important features. For state and county boundaries, the water and coastlines are derived from the coastlines of the 2020 500k TIGER Cartographic Boundary Shapefiles. These are erased to more accurately portray the coastlines and Great Lakes. 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 Census tracts with no population that occur in areas of water, such as oceans, are removed from this data service (Census Tracts beginning with 99). 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 file available from the American Community Survey Summary File Documentation page. Negative values (e.g., -4444...) have been set to null, with the exception of -5555... which has been set to zero. These negative values exist in the raw API data to indicate the following situations: The margin of error column indicates that either no sample observations or too few sample observations were available to compute a standard error and thus the margin of error. A statistical test is not appropriate. Either no sample observations or too few sample observations were available to compute an estimate, or a ratio of medians cannot be calculated because one or both of the median estimates falls in the lowest interval or upper interval of an open-ended distribution. The median falls in the lowest interval of an open-ended distribution, or in the upper interval of an open-ended distribution. A statistical test is not appropriate. The estimate is controlled. A statistical test for sampling variability is not appropriate. The data for this geographic area cannot be displayed because the number of sample cases is too small.
本图层基于具体族裔来源展示西班牙裔或拉丁裔(Hispanic or Latino)人口分布,制图范围涵盖普查区(census tract)、县及州界。本服务每年更新一次,纳入最新发布的美国社区调查(American Community Survey, ACS)五年期数据,包含统计估计值与误差边际(margin of error)。本图层还附带与该主题相关的衍生计算属性,可用于制图或分析工作。本图层通过符号化渲染展示西班牙裔或拉丁裔人口占比。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:2016-2020年ACS,对应数据表为B03001。 数据来源:美国人口普查局(United States Census Bureau)美国社区调查API。 API调用日期:2022年3月17日。 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、新闻及更新。 本即用型图层可在ArcGIS Pro、ArcGIS Online、其可配置应用程序、仪表板、Story Maps、自定义应用程序及移动应用中使用。数据亦可导出用于离线作业流程。如需了解更多关于ACS图层的信息,请参阅常见问题解答(FAQ)。使用本数据时,请引用美国人口普查局及ACS相关成果。 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计值不确定程度通过误差边际体现。本图层展示的误差边际为90%置信水平下的结果,即估计值减去误差边际与估计值加上误差边际所构成的区间(置信下限与置信上限)有90%的概率包含真实数值。除抽样变异性外,ACS的估计值还存在非抽样误差(相关讨论详见《数据精度》章节),但本数据表未体现非抽样误差的影响。 数据处理说明:本图层每年在美国人口普查局发布最新ACS数据版本时自动更新,通常为每年12月。本图层始终包含最新可用的ACS五年期估计值,更新时间紧跟人口普查局的发布日程,前后间隔不超过数日。点击此处可了解更多ACS数据发布相关信息。 地理边界数据源自美国人口普查局TIGER(拓扑集成地理编码与参照系统,Topologically Integrated Geographic Encoding and Referencing)地理数据库,具体为全国州以下地理数据库(文件名为tlgdb_(年份)_a_us_substategeo.gdb)。边界数据与统计数据同步按年更新,且边界版本与人口普查局规定的数据版本严格匹配。为满足制图需求,本图层已移除普查边界中的水体及海岸线要素。针对普查区图层,水体剔除范围源自TIGER提供的2020年区域水文边界子集。普查区边界中已移除面积≥5000万平方米的大中型水体及河流,以及其他重要地物。针对州及县级图层,水体与海岸线数据源自2020年500k分辨率TIGER制图边界Shapefile中的海岸线图层,移除该要素以更精准地展示海岸线及五大湖区域。数据表格中仍保留原始的AWATER与ALAND字段(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及波多黎各。本数据服务已移除海洋等水域区域内无人口的普查区(即代码以99开头的普查区)。 占比、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的相关规范。字段别名的命名依据美国社区调查汇总文件文档页面提供的表框架文件生成。 原始API数据中的负值(如-4444…)已被设置为空值,仅-5555…被设置为0。原始API数据中的这些负值用于标识以下场景: 1. 误差边际字段表明,无有效抽样观测值或抽样观测值过少,无法计算标准误及误差边际,此时不适合开展统计检验。 2. 无有效抽样观测值或抽样观测值过少,无法计算估计值;或因其中一个或两个中位数估计值落在开放式分布的最低区间或最高区间,无法计算中位数比值。 3. 中位数落在开放式分布的最低区间或最高区间。 4. 不适合开展统计检验。 5. 估计值已受控。 6. 针对抽样变异性的统计检验不适用。 7. 因抽样样本量过小,无法展示该地理区域的数据。
