Abstract
Abstract In this research note, we propose a new typology of geographic places for use in advancing Canadian politics research on the political effects of place. We use hierarchical cluster analysis (HCA) to inductively derive place types from Aggregate Dissemination Areas (ADAs), a fine-grained unit of geography covering all of Canada, newly available from Statistics Canada. Using this approach, we uncover seven distinct place types, adding nuance to earlier more aggregated approaches focused on urban-rural (or urban-suburban-rural) distinctions. We then demonstrate our typology's utility by showing how it provides new insight into the relationship between place and politics, using the example of the 2021 Canadian federal election. We conclude with a discussion of how our approach may be used to further the study of Canadian political geography, and we make available all files necessary for researchers to merge our place types with survey data for this purpose.

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.
