ACS Disability by Type Centroids

Overview This feature service provides American Community Survey disability estimates for U.S. centroids at state, county, and census tract levels. The layers summarize civilian noninstitutionalized population counts and disability characteristics, with detailed measures for hearing, vision, cognitive, ambulatory, self-care, and independent living difficulty. It also includes age- and sex-specific breakdowns and calculated totals and percentages that support comparative demographic analysis. Feature Layers State: State-level centroid features with ACS disability estimates and supporting measures for total population, sex, age groups, disability types, and calculated totals. County: County-level centroid features with the same disability profile and demographic breakdowns, linked to county name and state name for statewide and regional analysis. Tract: Census tract centroid features with detailed ACS disability estimates and demographic summaries for tract-level planning, equity assessment, and accessibility analysis. Data Themes Civilian noninstitutionalized population totals Disability counts by type Age and sex group summaries Calculated disability totals and percentages Geographic Coverage The service covers the United States across state, county, and census tract geographies. Use Cases Demographic and accessibility analysis Community needs assessment Equity and inclusion planning Regional comparison of disability prevalence Cartographic display of ACS disability indicators at multiple scales Source Context The attributes follow American Community Survey-style disability estimate fields and include calculated summary measures that aggregate disability types across age groups.## 概述 本要素服务提供美国州级、县级及普查分区（census tract）级质心的美国社区调查（American Community Survey, ACS）残疾统计估算数据。各图层汇总了非机构化平民人口规模与残疾特征维度，涵盖听力、视力、认知、行动、自理及独立生活困难六大类细分残疾指标，同时包含按年龄与性别划分的统计细分项，以及用于对比性人口统计分析的计算汇总值与占比数据。 ## 要素图层 1. **州级图层**：搭载ACS残疾统计估算值及配套辅助统计量的州级质心要素图层，覆盖总人口、性别分组、年龄组别、残疾类型及计算汇总值等全维度统计信息。 2. **县级图层**：包含同类残疾特征与人口统计细分项的县级质心要素图层，关联县级行政名称与所属州名，支持全州及区域层面的对比分析。 3. **普查分区图层**：集成详细ACS残疾统计估算值与人口统计汇总信息的普查分区质心要素图层，可用于分区级规划、公平性评估与无障碍分析场景。 ## 数据主题 - 非机构化平民人口总规模 - 按残疾类型细分的残疾人数统计 - 按年龄与性别分组的统计汇总项 - 计算生成的残疾总人数与占比 ## 地理覆盖范围 本服务覆盖美国全境的州级、县级及普查分区级地理单元。 ## 应用场景 1. 人口统计与无障碍分析 2. 社区公共服务需求评估 3. 公平性与包容性规划 4. 残疾患病率的区域对比分析 5. 多尺度下ACS残疾指标的可视化制图展示 ## 数据来源说明 本服务的属性字段严格遵循美国社区调查的残疾统计估算字段规范，包含按年龄组聚合各类残疾类型后得到的汇总统计量。
