The development of Liverpool since the 1950s has spread the accent into nearby areas such as the towns of Runcorn and Widnes. Variations within Scouse have been noted: the accent of Liverpool's city centre and northern neighbourhoods is usually described as fast, harsh, and nasal, while the accent found in the southern suburbs of Liverpool is typically referred to as slow, soft, and dark. Popular colloquialisms have shown a growing deviation from the historical Lancashire dialect that was previously found in Liverpool, as well as a growth in the influence of the accent in the wider area. Natives and/or residents of Liverpool are formally referred to as Liverpudlians, but are more often called Scousers.
