Economists have used historical heights as markers of health, living standards, and long-run development. Although possible selection bias has been debated, height measurement error is less studied. I analyze novel administrative data of male Indian indentured laborers with repeated measurements of adult height to answer an important underlying question of precision. Laborers were measured by British colonial officials on departure in India and again several years later when opting to return to India. I find no height differences for men who had attained full height in India. Younger men continued to grow even into their twenties. A caste subgroup analysis finds mostly similar results. This paper provides some of the first evidence showing height consistency in repeated measurements of adult heights.

经济学家使用历史高度作为健康、生活水平和长期发展的标志。尽管可能的选择偏差存在争议，但对高度测量误差的研究较少。我通过重复测量成年身高来分析印度男性契约劳工的新管理数据，以回答一个重要的潜在精度问题。英国殖民官员在离开印度时对劳工进行了测量，几年后在选择返回印度时又进行了一次测量。我发现在印度达到正常身高的男性没有身高差异。甚至到了二十几岁，年轻男性仍在继续成长。种姓亚组分析发现大部分相似的结果。本文提供了一些初步证据，显示了重复测量成人身高的身高一致性。
