Demographic estimates for the number of individuals living in the U.S. as of 2023 who have potentially benefited from Plyler since 1982, and could do so in the future, are based on a combination of three accessible and known populations:
- Previously undocumented individuals, who are now lawful permanent residents or U.S. citizens and who benefited from Plyler protections during the 1980s until they were legalized as part of the 1986 Immigration Reform and Control Act (IRCA);
- Currently undocumented adults who entered the U.S. before age 18 and who would have had access to public education in the U.S.; and
- Currently undocumented children who were ages 5 to 19 years old in 2023 and who currently benefit from Plyler.
For the first group of current permanent residents and U.S. citizens that legalized under IRCA, data from the Immigration and Naturalization Service were consulted to obtain the number of individuals, according to their year and age of entry into the U.S., who would have benefited from Plyler between 1982 and their year of lawful status. Some 430,000 individuals meet these criteria as being covered by Plyler’s guarantees prior to legalization. This total target number was used to randomly select individuals according to age, year of entry, and nationality characteristics in the 2022 ACS. This is likely an overcount, as the target population was not reduced by emigration or mortality. As a robustness check, the ratio of those with LPR vs. U.S. citizenship mirrored findings in the uptake of U.S. citizenship for this population more than a decade after obtaining LPR through IRCA.
Among currently undocumented adults who have benefited from Plyler in the past, the number of individuals is determined by immigration status assignments assigned by FWD.us researchers in the 2022 ACS and projected through the end of 2023. An estimated 2.6 million adults still living in the U.S. meet this criteria as having been covered by Plyler. This is certainly a substantial undercount of the total number of once-undocumented adults benefiting from Plyler as there were likely other undocumented students with access since 1982, but who have since died, left the U.S., or adjusted status through means other than IRCA.
Undocumented children who are currently benefiting from Plyler and who will do so in the future were also determined by FWD.us researchers’ immigration status assignments. Particularly important for this estimated population of 1.8 million children are the projections through to the end of 2023 to account for the population of new arrivals, including children, who do not appear in the 2022 ACS.
In all, an estimated 4.8 million individuals have benefited from, or are currently benefiting from, access to free public K-12 education since the Plyler decision and lived in the U.S. in 2023. These estimates describe access and not actual use. It is possible that many undocumented individuals who came to the U.S. as teenagers never went to school and thus never benefited from public education in the U.S. Overall, the estimates are considered conservative, particularly regarding Plyler’s retrospective gains.
Undocumented individuals include those with a protected status, such as DACA, TPS, parole, people seeking asylum, or other protections from deportation. All estimates for the retrospective gains and prospective losses from Plyler rely on these demographic assignments in the 2022 ACS, projected to 2023, including any relevant individual-level characteristics that can be of use to estimation. Consequently, 2023 is the pivot year whereby all measures, past and future, hinge, including constant 2023 dollars for economic outcomes.

Retrospective economic gains from Plyler are based on synthetically constructed income histories of Plyler-benefiting individuals going back to 1982 when each individual turned 18 and likely entered the workforce. A series of counterfactual income histories in the without-Plyler scenario were calculated based on their educational attainment frozen in the past, reducing their likely actual income by about 6% for every uncompleted year of education. Individuals for the without-Plyler scenario, now without schooling, are assumed to enter the workforce at age 14. The net retrospective economic gains are the total aggregate cumulative incomes for the without-Plyler scenario subtracted from the Plyler scenario, reported in 2023 dollars.
Prospective economic losses if Plyler were overturned are first based on predicted income for each current Plyler-benefiting individual in 2023, based on the educational attainment of similar, undocumented adults in 2023. Assuming employment after 12 years of schooling, the future incomes of current Plyler-benefiting individuals are allowed to follow an inverted U-shaped earnings curve to accommodate the likely peak of earnings by their mid-fifties and decreasing through to retirement at age 70. By contrast, the predicted income for the same group, but under the without-Plyler scenario, are allowed to enter the workforce at age 14, following a similar earnings curve, but without the premium of additional education beyond their frozen level in 2023. The net prospective losses are the aggregate cumulative incomes for the Plyler scenario subtracted from the without-Plyler scenario.
Plyler and without-Plyler scenario totals, for both the past gains and the future losses, were reduced by the proportion of current Plyler adults who were not employed (24%) as of 2023. This allows for a more conservative set of estimates, as we would expect not all individuals to be in the labor force.

State fiscal estimates were calculated as the likely total taxes paid by those benefiting from Plyler since 1982 according to the same income histories developed for the economic analyses. Tax rates, which included all forms of taxation, were drawn by state from the Institute on Taxation and Economic Policy’s (ITEP) 2024 tax tables. All individuals benefiting from Plyler were assumed to pay state and local taxes according to percentile cut-points for family income. (According to the 2022 ACS, family income distribution was similar to individual-level income distribution). To simplify this exercise, tax rates were considered constant prior to and following 2024 tax rates. Past income histories were projected through to age 70 and discounted by 24% to conservatively assess the aggregate, cumulative income of working persons only.
For the cost of Plyler-benefiting individuals, the 2023 cost of educating a student in each state, according to the 2022 Census of Governments, was calculated according to the number of years they would have benefited from Plyler. Individuals were assumed not to have moved states during their educational attainment or working lives. The aggregate, cumulative costs of their public education, conservatively assuming all went to school for all 12 years, were calculated and subtracted from their total tax contributions for each state. The net result is the additional tax revenue in each state from the Plyler-benefiting population for their lifetimes beyond the cost of educating them for K-through-12 school years.

Children pushed into poverty without Plyler is based on the number of dependent children (less than 18 years old) in 2023 who fall below the family poverty level after the replacement of without-Plyler income in 2023 of their Plyler-benefiting parents, as calculated for retrospective income histories described above. Children pushed into poverty are the additional number of children who would live below the 100% family poverty level in 2023 after these income adjustments without Plyler.

Past labor force gains through Plyler were calculated using the educational attainment for the total U.S. working population, creating groups of occupations and industries where the overwhelming majority (75%) achieved a certain education threshold for a particular occupation or industry. Three categories are included: (1) jobs requiring at least some college education; (2) jobs requiring at least a high school diploma; and (3) jobs requiring less than a high school diploma. Using Plyler status assignments listed earlier in the 2022 ACS, the analysis aggregates the number of adult Plyler beneficiaries who have been gained in occupations typically requiring some higher education and in occupations requiring at least a high school education.
Potential future labor force losses without Plyler were calculated using a random forest algorithm to predict the occupational and industrial skill levels that children currently benefiting from Plyler might possess as adults. The model is trained on data from previous adult beneficiaries of Plyler who are prime working age, using a range of predictor variables, including years of education, age at arrival, country of birth, sex, race, Hispanic ethnicity, state of residence, and protected legal status.

Health outcomes with and without Plyler are based on educational attainment, usually in the completion of secondary school, assessing the gains and losses with and without Plyler for Plyler beneficiaries. Since most health outcomes are based on annual events, the total number of person-years for Plyler-benefiting individuals is assessed both for the Plyler-benefiting adult population from 1982 to 2023 and also for Plyler-benefiting adults and children for future years. All metrics are calculated for lifetime health outcomes, with education typically presenting greater influence in later years of life, long after completing their education in public schools.
Although immigrants tend to be healthier than their counterparts in the U.S. and their origin countries, their health advantage may not persist. Research shows that immigrant health converges with the health of the U.S.-born population over time, particularly for immigrants who arrive as children.
Each health outcome calculation relies on a different set of studies to estimate health-related impacts of Plyler. A limited number of studies are available for health-related outcomes by education and associated lifetime impacts on health, particularly for the undocumented immigrant population. Thus, the outcomes presented here are meant to be indicators of the potential retrospective gains and prospective losses associated with Plyler. The negative health outcomes averted through Plyler’s guarantees are not meant to be exhaustive, but a sampling of potential outcomes. The analyses offer a window into the devastating lifetime health consequences that a generation of immigrant school children could experience throughout their lifetimes without access to public education.
Obesity. A randomized controlled trial of an obesity prevention program among middle schoolers found that participation in the program lowered the risk of adulthood obesity. The report applied the results of this experiment to the number of individuals with and without access to school-based programs to derive the number of overweight adults averted through Plyler in the past and in the future. Total medical costs associated with excess obesity are based on the average cost per capita published in the same study.
Lifetime disability. Educational attainment has a direct relationship with the onset of disability in later life. Disability is defined as being unable to conduct activities of daily living like bathing, dressing, walking, eating, etc. A recent study found that people without a high school diploma spent more years in disability than people with a high school diploma, and differences were more pronounced among women. Rates of lifetime disability years from this study were applied by sex to the Plyler-benefiting population to estimate the potential impact of Plyler on disability. Excess expenditures associated with increased disability were estimated using costs published in a separate study.
Infant mortality and preterm births to Plyler Women. Studies consistently find that women with less education have a greater risk of preterm birth and infant mortality than women with more education. The report estimates excess infant mortality and preterm births by applying the increased risks in the absence of Plyler’s guarantees to the expected number of births projected by the total fertility rate for Hispanic women living in the U.S.
Childhood influenza. School-based immunization programs improve vaccination rates and health outcomes for students and their immediate family members. The analysis drew on clinical trial studies of school-based influenza immunization programs to calculate healthcare cost savings associated with greater school access through Plyler, net of costs to administer vaccines.
Lifetime depression. A twin study that controlled for genetic and environmental factors found that depression decreased with greater educational attainment. The analysis applied the excess depression rates associated with lower education from the twin study to the Plyler-benefiting population to estimate excess lifetime depression in the absence of Plyler’s guarantee of equal access to public education. Excess healthcare costs due to increased depression were calculated using depression-associated health expenditures published in a separate study.
