National Neighborhood Data Archive (NaNDA): Neighborhood-School Gap by Census Tract and ZIP Code Tabulation Area, United States, 2009-2010 and 2015-2016

This study contains measures of neighborhood-school gap for 2009-2010 and 2015-2016. Neighborhood-school gap (NS gap) refers to the discrepancy between the demographics of a public school and its surrounding community. For example, if 60 percent of a school's student body is Black, but 30 percent of the neighborhood population is Black, the school has a positive Black neighborhood-school gap. These datasets measure gaps in race and poverty between elementary school student populations and the census tracts and ZIP code tabulation areas (ZCTAs) that those elementary schools serve. Data is at the census tract and ZCTA level. Supplemental data containing component variables used to calculate NS gap at the school and block group level is also available.

本项研究包含2009-2010年度及2015-2016年度的邻里学校差距指标。所谓邻里学校差距（NS差距）是指公立学校学生群体与其周边社区人口构成之间的差异。例如，若一所学校的学生群体中60%为黑人，而该邻里社区黑人人口占比仅为30%，则该学校拥有正向的黑人邻里学校差距。这些数据集测量了小学学生群体与为其服务的普查区以及邮政编码统计区域（ZCTA）在种族和贫困程度方面的差距。数据层面至普查区和ZCTA，此外，还提供了用于计算学校和街区群体层面邻里学校差距的组成部分变量的补充数据。
