Breaking the figures up by wards is not helpful.
As previously discussed, these wards have strange boundaries - eg large parts of upper sydenham is included in the FH ward, and the Perry Vale ward also eats into SE26.

The breakdown wanted is all the methods of polling split by postcode.

Also the bias towards the phone poll is worrying.

Wrong. Anyone who took the time to research the details (ie like find where WW is), and actually filled in the form (which had a much better distribution this time), were excluded from the telephone poll.

The telephone poll is only representative of those who most likely did not have the data to make an informed decision. And if they did have view, they did not make the time to return the form, so maybe were not too fussed either way.

A telephone poll would be useful in finding out where people swim, how they get there, what facilities they want, would they return to FH pools, etc rather than resolving complex ideas where competing needs maybe have to be traded off.

The key question is not something that can be resolved by an on the spot phone poll, so, for me, this method carries the least weight.
