St. Croix, the largest of the U.S. Virgin Islands, has a predominantly Black population, reflecting its complex history of West African heritage and the transatlantic slave trade. According to the most recent demographic data available in 2026, approximately 70% to 75% of the population identifies as Black or Afro-Caribbean. This community is a vibrant mix of "Crucians" (those born on the island) and individuals from neighboring Caribbean nations like St. Kitts, Nevis, Antigua, and St. Lucia who have moved to the island for economic opportunities over the decades. The culture of St. Croix is deeply rooted in this majority population, visible in the island's music (such as Quelbe), the annual Crucian Christmas Festival, and the local cuisine. While there are also significant White and Hispanic (primarily Puerto Rican) populations on the island, the Black community remains the demographic and cultural backbone of St. Croix. This majority status has a profound impact on the island's political landscape, social structures, and its distinct identity as a center of African-diasporic history within the United States territories.
