 Barbados hosts a large diaspora population of Guyanese, of whom (in 2005) 5,032 lived there permanently as citizens, permanent residents, immigrants (with immigrant status) and Caricom skilled nationals; 3,200 were residing in Barbados temporarily under work permits, as students, or with "reside and work" status.A further 2,000-3,000 Guyanese were estimated to be living illegally in Barbados at the time.Migration between Barbados and Guyana has deep roots, going back over 150 years, with the most intense period of Barbadian migration to then-British Guiana occurring between 1863 and 1886, although as late as the 1920s and 1930s Barbadians were still leaving Barbados for British Guiana.
