Physical growth and ethnic inequality in New Zealand prisons, 1840–1975
Bibliographic record
Abstract
The British colonization of New Zealand after 1840 was marked by an unusual concern compared to other settler colonies to incorporate the indigenous Māori population into the new society. But despite a continuing political rhetoric of protection and sovereignty, Māori have historically had lower living standards and, since the 1920s, higher rates of incarceration than European-descended New Zealanders (Pākehā). In this article, the authors examine differences between Māori and Pākehā over 130 years using prison records. Aggregate data from the Ministry of Justice shows long-term change and differences in incarceration rates. Using a data set of all extant registers of men entering New Zealand prisons, the authors show change over time in convictions and in height. The adult statures of Māori and Pākehā were similar for men born before 1900, but marked differences emerged among cohorts born during the twentieth century. By the Second World War, the gap in adult stature widened to around 3 cm, before narrowing for men born after the Second World War. Periods of divergence in stature are paralleled by divergence in fertility and indicators of family size, suggesting the possibility that increasing fertility stressed the economic situation of Māori families. The prison evidence suggests that inequalities in ‘net nutrition’ between Māori and Pākehā are long-standing but not unchanging – indeed, they increased for cohorts born in the early twentieth century. A subset of the data describing adolescents confirms that, among those born after 1945, the ethnic differential was already visible by the age of 16.

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.
