Information on the number of ambulance and air ambulance crews and the ratio of ambulance crews to 1,000 populations for north-east Essex and England is not collected centrally. However, data on ambulance work force are contained within table 5 of the Information Centre's Non-Medical Workforce Census Bulletin (1996-2006), which is available via the Information Centre for health and social care website at:
