As at 1 January 2007, 240 civil servants who have a work address in one of the four Belfast constituencies have a home address in the Foyle constituency. The figure includes permanent and casual, industrial and non-industrial Northern Ireland civil service staff working within the 11 departments and agencies, the NIO, the PSNI and the NI Assembly. It does not include staff on career break.
No estimate has been made of the number of cars carrying these civil servants which make the return journey between Derry and Belfast on a daily basis.
