Changing Intergroup Boundaries in Brazilian Marriages: 1991-2008
Bibliographic record
Abstract
Using data from the 1991 and 2000 Censuses, and the 2001 and 2008 PNAD of Brazil, this paper examines change in educational, racial and religious intermarriage. Different perspectives on social change make different predictions regarding shifts in the magnitude of marital homogamy within these three social characteristics. Racial homogamy is less pronounced in Brazil than in a variety of other contexts, educational homogamy is comparable to that reported in the United States, and religious homogamy is much more pronounced than either educational or racial homogamy. The most common pattern of social change is increased fluidity in mate selection. Homogamy parameters are becoming smaller for race, education and religion, but the pattern of change is not uniform. Boundaries appear to be increasing at the two tails of the education distribution and for some religious categories.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
