Intergenerational Controversy and Cultural Clashes: Political Consequences of Demographic Change in the US and Canada Since 1990
Bibliographic record
Abstract
This chapter offers a general introduction to demographic trends and projections in the US and Canada between 1990 and 2040 and discusses the economic fortunes of various groups, their mobilization capacity, influence of institutions and a rhetoric of population change. While the demographics of the US and Canada have undergone similar changes, including population ageing and shifts towards non-White national origin and race, their political dynamics are quite different. In particular, the mobilization capacity of US minorities is hampered by voter eligibility rules, an issue less relevant in Canada. In both, federalist institutions devolve power to state or provincial levels, but when combined with demographics yield different political impacts in the two countries. Finally, the tenor of rhetoric surrounding demographics has been nearly opposite in the two countries, although demographics are important in both. The chapter concludes with a reflection on the continued salience of population issues in the political arena in the coming decades.

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.
