Consumption Patterns Among Aging Canadians: A Synthetic Cohort Approach
Bibliographic record
Abstract
Studies of pre- and post-retirement annual income have focused on the extent to which income falls at this crucial stage in life. Although these studies vary in scope and intent, the overall consensus is that the Canadian retirement income system provides income replacement rates that are in the excess of 60% to 70% for a plurality of Canadians, especially for those who had low incomes during their prime working years. However, little has been published on the extent to which retirees maintain their same levels of consumption. Using data from the Survey of Family Expenditures (FAMEX) and from the Survey of Household Spending (SHS), this study develops a synthetic cohort approach to determine how the consumption patterns of households headed by individuals in their late 40s (in the early 1980s) differ from those of a group of households headed by individuals in their early 70s (in the late 2000s). It finds that, even though the nature of consumption changes over time, the overall levels of consumption "per adult" do not decline by substantial amounts among Canadians as they age.

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.
