Suppose some government policy tends to help large communities rather than small ones.
I want to describe this as a noun.
Will "size-advantageousness of policy" be a good choice to describe that?
Or is there any better alternative?
I would try:
The bias of the policy toward large communities is such that...
Admittedly, this construction requires the prepositional phrase after it for clarity/specificity, but it can be used in the same noun phrase template that you provided.
You may refer to it as:
- A policy that discriminates against small communities.
I would always use the word discrimination which means:
the practice of unfairly treating a person or group of people differently from other people or groups of people
In your example, you could use:
The policy discrimination against small communities...
The discriminating policy against small communities...
Rather than size-advantageousness, could I suggest benefit-of-scale. I would use it as:
There is a benefit-of-scale to the policy, such it helps large communities much more than small communities.
