ACS School Enrollment by Boundary

Overview This feature service provides U.S. Census American Community Survey school enrollment statistics for geographic boundary layers at the state, county, and census tract levels. It supports comparisons of enrollment patterns for people age 3 and over, with detail for male and female populations across preschool, kindergarten, grades 1 through 12, college undergraduate years, and graduate or professional school. Feature Layers State : State boundary features with ACS school enrollment measures, land and water area, and standard geographic identifiers for statewide demographic analysis. County : County boundary features with the same school enrollment indicators, allowing county-level comparison of enrollment participation and school type distribution. Tract : Census tract boundary features with detailed ACS school enrollment attributes for fine-grained neighborhood analysis and local planning. Data Content The service includes detailed enrollment counts and related calculated indicators that summarize total enrollment, enrollment by gender, enrollment by school level, and private-school participation. These attributes support demographic profiling, educational access studies, and geographic comparison across multiple administrative levels. Geographic Coverage The layers cover the United States and its territories at national boundary scales represented by states, counties, and census tracts. The service is designed for broad geographic analysis across the full country using a common Census geography framework. Use Cases Educational demographics and school enrollment analysis Comparing public and private school participation State, county, and tract-level planning and reporting Community profile development and equity analysis Mapping ACS-based enrollment patterns in ArcGIS applications### 概览 本要素服务提供美国人口普查局美国社区调查（American Community Survey）的入学统计数据，涵盖州、县及普查街区（census tract）三级地理边界图层，支持对3岁及以上人群的入学模式开展对比分析，细分覆盖学龄前、幼儿园、1至12年级、大学本科及研究生/专业院校各阶段的男性与女性人口数据。 #### 要素图层 州级图层：包含ACS入学统计指标、水陆面积及标准地理标识符的州界要素，可用于全州范围的人口统计分析。 县级图层：包含同类入学统计指标的县界要素，支持县级层面的入学参与率与学校类型分布对比。 街区级图层：包含详细ACS入学统计属性的普查街区边界要素，适用于精细化邻里分析与地方规划。 #### 数据内容 本服务包含详细的入学人数统计与相关衍生指标，涵盖总入学人数、分性别入学人数、分学段入学人数及私立学校参与率等维度。这些属性可支撑人口画像构建、教育可达性研究及多行政层级的地理对比分析。 #### 地理覆盖范围 本图层覆盖美国及其所有领土，涵盖以州、县和普查街区为代表的各级地理尺度。本服务基于统一的人口普查地理框架，可支持全美范围内的广泛地理分析。 #### 应用场景 教育人口统计与学校入学情况分析 公立与私立学校参与率对比 州、县及街区级规划与报告编制 社区画像构建与公平性分析 在ArcGIS应用中绘制基于ACS的入学模式分布图
