 Igbo Americans introduced the Igbo word "okra" into the English language.The recent migrant population from Nigeria settled in many of the United States' larger cities and urban centres and had come largely in search of economic opportunities in the late 20th century.Because of the realities of slavery and its erasure of African heritage and customs, most people who identify as Igbo in the United States and speak the Igbo language at home are from these families that arrived in the 20th century and forth.
