Forming and encouraging families in Jamaica was a struggle from the very beginning of English colonization there, making Caribbean households transatlantic in nature. The explosion of plantation slavery in the 17th century prioritized economic expansion over white family cultivation. Likewise, planters were more concerned with profits than they were with enslaved families. Constant migration from Europe and Africa was therefore needed to keep populations stable for the whole history of slavery in Jamaica. The island’s demographic and political security was always tenuous as a result of this, and officials attempted numerous strategies to encourage family growth, among both the free and enslaved communities. As the island transitioned to freedom, regulating the definition of “proper” families became a weapon from which English authorities wielded imperial power. Racist sentimental toward Caribbean households created social tension when thousands of black Jamaicans emigrated to Britain after the Second World War. Their arrival produced new British households that challenged some British conceptions of domestic family life. Throughout this whole history, migration defined the growth and character of families in the Jamaican-British Atlantic World.
