Is There a Cohort Explanation for Declines in Elderly Migration?
Bibliographic record
Abstract
Previous research documented a dramatic decline in the residential mobility of elderly Canadians (65 years and older) since 1961. We examine more recent data from the 2011 and 2016 censuses to update findings and extend previous research. We first found that elderly residential mobility has continued to decline. There were substantial declines of 20 per cent and more for all types of residential mobility. Second, descriptive analysis of changes over time in the proportion of the population that lives in a different province than their province of birth for 1871 to the present suggests that the 1906-1925 birth cohorts experienced migration rates that were slightly higher than comparable later cohorts. Third, multivariate analysis of 1971-2016 interprovincial migration data shows that the 1906-1925 birth cohort who entered early adult years during World War II had higher migration rates than earlier or later birth cohorts. The cohort explanation accounted for 10 per cent of the decrease in elderly migration between 1981 and 2016. A cohort explanation can therefore contribute to understanding decreased elderly migration, but many questions remain for future study.

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.
