Housing as a Heuristic Condition in the Simultaneous Projection of Population and Households
Bibliographic record
Abstract
Conventional population projections regard individuals, rather than households, as population units of reference. Such an approach has been questioned on both methodological and empirical grounds. Furthermore, in applications to smaller populations, conventional population projections have repeatedly yielded poor results. The simultaneous projection of population and households, on the other hand, regards households as population units of reference, but, in applications based on the notion of the household composition matrix, it has occasionally yielded analytically infeasible results. In the present study I examine the simultaneous projection of population and households in a etropolitan area, under feasibility constraints. A housing-market specification is expressed as a feasibility condition against multipliers of the household composition matrix, extracted here for the Cleveland Consolidated Metropolitan Statistical Area (CMSA), 1990. The feasibility condition is shown to function as a gateway to exogenous considerations regarding the transfer of headship in households, and is exemplified in a forecast of population and households for the Cleveland CMSA.

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.
