How was Saint-Domingue's population divided by class and skin colour before the Haitian Revolution?

Before the Haitian Revolution, society in the French colony of Saint-Domingue was deeply fragmented by class and skin colour. By 1789, the population of approximately 556,000 was divided into three primary groups:12

• Enslaved Africans: Comprising roughly 500,000 people, this group formed the vast majority. Most were bosal (African-born) field-workers, though some served as household staff or skilled laborers. They endured brutal conditions, and many sought refuge as Maroons in the mountains.12
• European Colonists: Numbering about 32,000, this group was stratified into grands blancs (elite merchants and landowners), petits blancs (craftspeople and overseers), and blancs menants (laborers and small farmers).12
• Affranchis: This group of 24,000 consisted of free people of African or mixed African and European descent. While some were wealthy and owned enslaved people themselves, they faced systemic discrimination from Europeans and often aspired to higher social status, making their frustrations a key catalyst for the revolution.312
