Abstract
In the past 10 years, a historical change occurred in migration flows within North America: specifically, Mexico-U.S. migration reached zero net migration. Alongside Mexican adults returning to their homeland was an unprecedented number of U.S.-born minors. Little is known about this massive migration of U.S. citizen children. We analyze Mexican census data from 2000 to 2015 to estimate the size and characteristics of the population of U.S.-born minors residing in Mexico. Between 2000 and 2010, the population of U.S.-born minors doubled to more than half a million. The population stabilized, aged, and became longer-term Mexican residents thereafter. The large majority of U.S.-born minors are primary school-aged. Although concentrated in the northern border and traditional migrant-sending regions, U.S.-born minors are distributed throughout Mexico. The majority of U.S.-born minors live in Mexico with two Mexican-born parents, but one-third are separated from one or both parents, and most of those separated from parents reside with grandparents. We interpret these trends in reference to the determinants of Mexico-U.S. migration, transnational and mixed-status families, and the future spatial and social mobility of U.S.-born minors living in Mexico.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
