This article uses demographic data from nineteenth-century Angola to evaluate, within a West Central African setting, the widely accepted theory that sub-Saharan Africa's integration within the Atlantic world through slave and commodity trading caused significant transformations in slavery in the subcontinent. It specifically questions, first, whether slaveholding became more dominant in Angola during the last phase of the transatlantic slave trade; second, whether Angolan slave populations were predominantly female; and third, whether slavery in Angola expanded further during the cash crop revolution that accompanied the nineteenth-century suppression of the Atlantic slave trade. Besides making a significant contribution to understanding the demographic context of slavery in the era of abolition, the article aims to display ways in which historians can use the population surveys the Portuguese Empire carried out in Africa from the late eighteenth century.

It must be noted that the increase in the numbers of libertos coincided with a decline in the size of the non-captive population. To some degree the rising proportion of libertos in the total population may have reflected outmigration by non-captives. Furthermore, the figure of 13,300 libertos in Golungo seems improbable; most settler plantations were in Cazengo, which is where we would expect a greater increase in the number of enslaved workers.
