title: Physical well-being and ethnic inequality in New Zealand prisons, 1840-1975.
abstract: The British colonization of New Zealand after 1840 was marked by an unusual concern compared to other settler colonies for incorporating the indigenous population 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 paper we examine differences between Māori and Pākehā over 130 years using prison records. Aggregate data from the Ministry of Justice show long-term change and differences in incarceration rates. Using a dataset of all extant registers of men entering New Zealand prisons we 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 World War II the gap in adult stature widened to around 3 cm, before narrowing for men born after World War II. 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 into the early 20thcentury. 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 years.
