No Room for New Families? A Field Experiment Measuring Rental Discrimination against Same-Sex Couples and Single Parents
Bibliographic record
Abstract
We suggest that new forms of family households, especially same-sex couples and single parents, are likely to face discrimination in their interactions with rental markets. Following the contact hypothesis, we hypothesize that the geographic distribution of discrimination is likely to vary. Specifically, in places with more new family households we are likely to find less discrimination against these households. We investigate these issues in the metropolitan area of Vancouver, Canada, through analysis of 1,669 inquiries made about one- and two-bedroom apartments. Using a field experimental design similar to audit studies, we analyze landlord responses to five different two-person household scenarios, including one heterosexual couple, two same-sex couples, and two single parents. Evidence suggests that male same-sex couples, single mothers, and single fathers all face significant discrimination relative to heterosexual couples. The contact hypothesis was supported for male same-sex couples, but not for single parents. This could indicate that single parents are facing discrimination primarily based upon their economic marginalization rather than other forms of prejudice.

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.
