斯坦福研究：全美公立学校学生较疫情前减少逾100万，学校数量未减、师生比下降4%
Stanford University 研究人员 Thomas S. Dee 与 Jaymes Pyne 11月9日发布的工作论文分析了2010年至2024年间美国几乎全部公立学校的联邦数据。研究显示，自新冠疫情开始以来，美国公立学校学生人数减少超过100万；平均每所学校的学生人数在疫情后减少约18人，降幅约3%。
下降分布并不均匀：四分之一的学校如今的学生人数比疫情前至少减少15%，以普通小学计相当于至少减少70名学生，下降最明显的是小学与初中。与此同时，仍在运营的公立学校数量与2019年秋季基本相同，教师人数反而增加，全美师生比已较疫情前下降4%。
研究还引述加州的较新州级数据：加州自2019年10月以来流失超过400,000名学生，但关闭的学校不到1%。该论文以工作论文形式发表于 EdWorkingPapers，DOI 为 10.26300/60a8-kk19。
Stanford Study: U.S. Public School Enrollment Down More Than a Million Since the Pandemic, School Count Unchanged and Pupil-Teacher Ratio Down 4%
A working paper released on November 9 by Stanford University researchers Thomas S. Dee and Jaymes Pyne analyzes federal data on nearly every U.S. public school from 2010 to 2024. The study finds that the number of students in U.S. public schools has fallen by more than a million since the start of the COVID-19 pandemic, and that average school enrollment dropped by about 18 students, or 3%, after the pandemic.
The declines vary sharply. One in four public schools now enrolls at least 15% fewer students than before the pandemic, or at least 70 fewer students for the average elementary school, with the steepest losses in elementary and middle schools. Meanwhile, the number of public schools operating today is effectively the same as in fall 2019, the number of teachers has grown, and the national pupil-teacher ratio has fallen 4% from its prepandemic baseline.
Newer state data from California show the same pattern: the state has lost more than 400,000 students since October 2019 but closed less than 1% of its schools. The study was released as a working paper through EdWorkingPapers, DOI 10.26300/60a8-kk19.
