美国公共教育多样性
该数据集《Diversity_U.S._Public_Education》主要用于监督学习任务，数据形态以表格为主，应用场景偏向安全检测。 题目说明：Ethnic Diversity & U.S. Public Education makeup of U.S. public (1986–2018). 任务类型：表格监督学习。 建议流程：先做缺失值/异常值处理与特征编码，再比较逻辑回归、随机森林、XGBoost。 评估建议：使用分层切分或交叉验证，优先关注 F1、Recall、AUC 等分类指标。 可用文件：Diversity_U.S._Public_Education new.csv。 This graph was created in code R : From the mid - 1980s to 2018, the ethnic makeup of U.S. public schools shifted dramatically — schools became far more racially and ethnically diverse as the share of White students declined and Hispanic and other minority enrollments grew. By 2018, Hispanic students represented a significantly larger share of public school enrollment compared to the early 1990s, while White student proportions dropped substantially. These demographic trends reflect rising ethnic fractionalization in public education. Over the same period, educational outcomes and opportunities showed persistent gaps across racial and ethnic groups: minority students made gains in attainment (high school graduation and college attendance), but disparities in achievement and access to resources remained. Segregation patterns shifted unevenly — between - district segregation has increased even as within - district mixing often improved — and unequal representation persists in more selective public institutions.

This graph was created in code R :
From the mid - 1980s to 2018, the ethnic makeup of U.S. public schools shifted dramatically — schools became far more racially and ethnically diverse as the share of White students declined and Hispanic and other minority enrollments grew.
By 2018, Hispanic students represented a significantly larger share of public school enrollment compared to the early 1990s, while White student proportions dropped substantially. These demographic trends reflect rising ethnic fractionalization in public education.
Over the same period, educational outcomes and opportunities showed persistent gaps across racial and ethnic groups: minority students made gains in attainment (high school graduation and college attendance), but disparities in achievement and access to resources remained.
Segregation patterns shifted unevenly — between - district segregation has increased even as within - district mixing often improved — and unequal representation persists in more selective public institutions.
