Find number of folders in every sub-folder

This is not exactly Windows questions. I wasn't too sure where to post, hence posting here. Admins, feel free to move to appropriate forum.

Here is the task,
I have 'C:\Data' folder that contains 1000s of folders. Each Subfolder should ideally contain one child folder in which there are minimum 3 and maximum 6 files. I have noticed that some folders have ended up with more than one child folders. I would like to find out which of these subfolders have more than one subfolder.
Is there any utility or script that I can run to find out subfolders that contain more than one child subfolder and export it to CSV or something like that?

I am not aware of exact terminology of these folders so if I am not making any sense, pls comment and will clarify more.

Many thanks in advance.

In PowerShell, this will print out the total number of subfolders within each 1st level subfolder of the parent.

Code:

 Get-ChildItem -Directory | ForEach-Object {$_.name + "," + (Get-ChildItem -Directory  -Recurse $_.FullName|Measure-Obj
ect).count }

So for:
parent\
parent\child 1\child child 1\
parent\child 2\
parent\child 3\
parent\child 3\child child 3\child child child 3\
parent\child 3\child child 4\

Code:

PS C:\temp> cd parent
PS C:\temp\parent>PS C:\temp\parent> Get-ChildItem -Directory | ForEach-Object {$_.name + "," + (Get-ChildItem -Directory -Recurse $_.Full
Name|Measure-Object).count }
child 1,1
child 2,0
child 3,3
PS C:\temp\parent>
