I just created a casting and saw the drop down list of towns in Cambridgeshire. I find the list of towns in Cambridgeshire peculiar - Buckden, with a population of 3,000 is listed, as is Huntingdon with 19.380, but St Neots with 30,000 does not appear on the list (figures from Wickipedia). Wickipedia lists 13 major settlements in the county. but St Neots, St Ives and Wisbech are all missing from the PS list of around 60 towns. I can't even find Little Paxton's figures for population on Wickipedia but it appears on the drop down list.
Maybe putting major towns in the listing would be a good idea? As Wickipedia lists major settlements in the county (and I presume other counties as well) it may be more usefull in compiling the lists than whatever criteria has been used for the current lists.
Thanks for the feedback, we are aware of the slightly 'odd' town results which are showing, you are right that St Neots should be showing as a major place compared to Huntingdon and that is how the system should work but we have traced this issue down to some wrong information within the data we use for locations. We are working on resolving this.
