 Travel to work area

A Travel to Work Area or TTWA is a statistical tool used by UK Government agencies and local authorities, especially by the Department for Work and Pensions and Jobcentres, to indicate an area where the population would generally commute to a larger town, city or conurbation for the purposes of employment.As a measure based on urban areas and their commuter hinterland they are a form of Metropolitan Area, though as methods of calculation differ they cannot directly be compared with other specific measurements such as Metropolitan Statistical Areas in the United States.
