Estimating the Refugee Population from PUMS Data: Issues and Demographic Implications
Bibliographic record
Abstract
Discussions of immigration, settlement and adjustment within the U.S. do not typically refer to immigrant status (i.e., refugee versus family preference), and instead refer to the foreign–born population as an aggregate. Distinguishing between refugees and other immigrant arrivals likely means differences with respect to their geographic distribution and embodied human capital owing to differences associated with the reasons for immigration (forced versus voluntary), period of arrival, and immigration policy. The lack of differentiation by group within the existing literature is typically due to a shortfall of detailed information relating to admission status within publicly released data files. Yet concrete knowledge of differences by admission category is important in understanding overall patterns of settlement and adjustment within the foreign–born population. This paper therefore explores potential differences with respect to settlement and endowed human capital between immigrants and refugees. Identification of the major sources of refugees within Immigration and Naturalization Service data files allows the refugee population to be identified within the 1990 Public Use Microdata Sample (PUMS), therefore increasing the range of variables and measures associated with the refugee population available to researchers, and points to the diversity of the refugee population.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
