Some additional stats:

sk_country_mount 1.33Kb/px 0.13b/object 1.33Kb/px
sk_DownCity 10.94Kb/px 5.03b/object 10.94Kb/px
sk_MidCity 5.69Kb/px 4.31b/object 5.69Kb/px
sk_Factory 4.56Kb/px 0.31b/object 4.56Kb/px

So I think its not as simple as counting objects.
The Factory template has a high object count but a low Kb/object figure.
MidCity which as the lowest objects/px uses more memory/pixel than the dense looking Factory template.
Since the Factories will not occupy a high number of pixels I am not too concerned about all the cute walls. In fact I'm quite keen to keep them.

These figures are based on the object count and file size of the inBuilding.txt files.

Isn't maths fun
