Immigration enforcement hurts many aspects of public life, and public schools have not been spared. ICE enforcement campaigns in cities like Washington and Minneapolis have turned public schools into staging grounds for raids: ICE agents are arresting parents and students who are suspected to be undocumented, and spreading fear among immigrant children and their families and school officials. Additionally, anti-immigration advocates are making a play to overturn a landmark Supreme court ruling, Plyler v. Doe, which ruled that states cannot deny students a free public education based on their immigration status.
In the last two years, Republicans in Tennessee have attempted to push legislation that would violate Plyler to set the stage to challenge the court decision (although neither proposal passed). Last year, the state proposed charging undocumented students tuition for public schools, and this year, Tennessee attempted to pass legislation to track the immigration status of all public school students.
The 1982 ruling of Plyler v. Doe is notable because it stated that the harm of not educating undocumented children would be worse for society than providing a basic education to all children in the U.S. The ruling recognized the huge positive spillovers public education has on the U.S. labor market, public health, and civil society and that leaving immigrant children out of public education would create an “underclass” in U.S. society.
Moreover, if the move to deny public education to children in the U.S. is successful, particularly in pockets of the country where immigrant children are a substantial share of the student population, it will lead to an extraordinarily high cost for the students who remain in public school.
Some school costs are hard to adjust, regardless of the number of students
Across the country, an estimated 17% of school-aged children live with at least one noncitizen adult, according to the Kaiser Family Foundation. If these students were to leave suddenly, schools would be left to educate a fewer number of kids without any time to adjust their fixed costs. For example, when Alabama passed an immigration data collection law, more than 13% of Hispanic schoolchildren withdrew from classes.
At first, it would seem that reducing enrollment would reduce both total revenue and the number of students needing educational services proportionately, which should leave the schools’ ability to provide education unaffected. But schools can’t adjust every educational cost quickly: School bus routes still need to circulate to all stops, even if there is one fewer child in need of transit; buildings need to be heated and cooled, even if classroom size goes down; and guidance counselors and support staff are still required to support the remaining students.
School districts will pay more per pupil if student enrollment declines because of immigration enforcement
Since these fixed costs can’t be adjusted in the short run, when total revenue declines due to families’ fears of deportation, districts are stuck paying more per pupil on costs they can’t adjust. Effectively, native-born students who remain in public schools receive no additional benefit when immigrant students are denied services and rights. Districts instead will be paying more on costs that can’t be adjusted and getting less on the costs that can be adjusted for fewer students.
Calculating the cost under two different scenarios
We call all the costs of downward adjustment that occur when enrollment is reduced the fiscal externality. This means the per-pupil funds each district would require to maintain the same level of spending for remaining public school students due to a rapid decline in enrollment. This cost is entirely borne by state and local education budgets and leaves districts unable to deliver the same level of instruction to the remaining public-school pupils.
For districts with a large share of school-aged children in immigrant families, the costs of losing these students could be substantial. Table 1 shows the top-25 school districts, based on the number of K–12 students that are in immigrant families and the corresponding fiscal externality for two scenarios. In the first scenario, half of these students stop attending public school (referred to as the lower bound in the table). In the second scenario, all of these students stop attending public school (referred to as the upper bound in the table).

The implications of a reversal of Plyler v. Doe or any type of policy restricting immigrant children’s access to public education would be extreme for these districts. In Houston, Texas, where 62% of students in the school district are Hispanic, we estimate that nearly 63,000 students may live in a household with immigrants and as such, might be vulnerable to dropping out of school due to anti-immigration efforts. The lower bound shows the costs if half of these students stopped showing up. Houston School District would have to reduce services by $1,654 for each remaining (and disproportionately native-born) public school student. This decline translates to a total fiscal externality of $268 million a year, or 11% of the total budget for the school district.
The extraordinarily high cost to native-born students of losing students in immigrant families due to anti-immigrant policies highlights the hypocrisy in the anti-immigrant movement. If all students in immigrant families stopped attending public school tomorrow, not only would those students suffer from the lack of public education, but the quality of public education would be much worse for the remaining students in those same schools. In short, no one wins. When the costs are tallied up, it’s clear that these policies are not about improving education quality for native-born students, but instead are malicious attacks on the institution of public education in the U.S.
