Certainly it would be very difficult to introduce any statistical rational erm to the desegregation of Greater York to its district components, bearing in mind the small populations er in some of the Greater York er districts, we think that the general level of detail erm in the structure plan is appropriate, and we think to go down to any finer detail would be an inappropriate to a structure plan, and thirdly I think on that issue, er we would think that it would prejudice erm the work that District Council would want to do erm in their er local plans.
