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.
