A Peculiar Sample: The Selection of Slaves for the New Orleans Market
研究发现，国内奴隶贩子为了增加利润，会选择身高更高的奴隶运往新奥尔良市场，导致运输清单构建的年龄/身高曲线存在向上偏差，对儿童影响较大。
Domestic slave traders selected taller slaves for shipment to the New Orleans market in order to increase their profits. Because traded slaves made up a large share of the slaves shipped coastwise, age/height profiles constructed from the shipping manifests are biased upwards. The extent of the bias appears to be small for adult slaves but not for children; those listed on the manifests were taller than the general population of a comparable age.
