Abstract
This report finds that Philadelphia's long tradition of high homeownership is changing. From 2000 to 2012, homeownership declined in this city as well as others across the United States. But the drop has been more pronounced in Philadelphia, with sections of Northeast Philadelphia recording the biggest decreases. The decline, which has been accompanied by an increase in renting, is largely due to stagnant incomes, rising home prices, tight credit standards for mortgages, and shifting attitudes toward buying a home, particularly among the city's growing number of young adult residents. Also examined in the report are the changing demographics of owner-occupants in Philadelphia and its neighborhoods, including the share of homes owned by low-income residents and families, and those owned free and clear, without mortgages.

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
