Living Conditions in Côte d'Ivoire, Ghana and Western Africa 1925-1985: What Do Survey Data on Height Stature Tell Us?
Bibliographic record
Abstract
Abstract- We find with survey data that the increase in height stature experienced by successive cohorts born in Côte d'Ivoire and Ghana during the late colonial period (1925-1960) is almost as high as the increase observed in France and Great-Britain over the 1875-1975 period, even when correcting for the bias arising from old-age shrinking. In contrast, the early post-colonial period (1960-1985) is characterized by stagnation or even reversion, not only in Côte d'Ivoire and Ghana but also in other countries in Western Africa. We argue that the selection effects linked to the interactions between height and mortality cannot give account of these figures. We then disaggregate these national trends by parental background and district of birth, and match individual data with district-level historical data on export crop (cocoa) expansion, urban density and colonial investment in health and educations. We provide evidence that a significant share of the increase in height stature may be related to the progresses of urbanization and of cocoa production.

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.
