Evidence drawn from records of auctions held by the Royal African Company in Barbados between 1673 and 1723 is used to obtain annual estimates of slave prices by demographic category. These price series are then used to investigate the implications of an economic analysis of the demographic composition of the slave trade. The results provide quantitative support for the prediction that rising slave prices in the West Indies caused an increase in the share of children among the population of slaves in the transatlantic trade. This economic effect may have been a significant link between American slave markets and the demographic history of black populations in both Africa and America.
