Linguistic research conducted in the early 2010s suggests that today, certain elements of cockney English are declining in usage within the East End of London and the accent has migrated to Outer London and the Home Counties. In parts of London's East End, some traditional features of cockney have been displaced by a Jamaican Creole-influenced variety popular among young Londoners (sometimes referred to as "Jafaican"), particularly, though far from exclusively, those of Afro-Caribbean descent. Nevertheless, the glottal stop, double negatives, and the vocalisation of the dark L (and other features of cockney speech) are among the Cockney influences on Multicultural London English, and some rhyming slang terms are still in common usage.
