It is alleged that European slave traders were fairly well informed about various African ethnicities, leading to slavers' targeting certain ethnic groups which plantation owners preferred. Particular desired ethnic groups consequently became fairly concentrated in certain parts of the Americas. Elements of Igbo culture can still be found in these places. For example, in Jamaican Patois , the Igbo word unu, meaning "you" plural, is still used. This term had originated from the reported prevalence of these skin tones among the Igbo but eastern Nigerian influences may not be strictly Igbo.
