A THIRD of the population living in Britain's city centres moves every year, research revealed.

The study of the transitory nature of the inner city resident - three times higher than the rest of the country - showed the majority were young, with two thirds of inhabitants aged between 18 and 34.

Single people also opted for the bright lights, with residents in city centres twice as likely as the rest of the country to not have a partner.

The Institute for Public Policy Research Centre for Cities, found Manchester's city centre population soared from less than 1,000 in the late 1980s to more than 15,000 in 2005.
