I know of 9 starter systems, likely to be at least a few more out there. I started in Aiabiko
The problem is 7 of those spawn points are barely used.
In gamma I originally spawned at LHS 1914, a quiet system 110 ly away from Sol, with lots of stations and outposts in it, in a nice cluster of sytems 10 ly apart from each other at the most. In my opinion a very good spawning area. I never saw any new player in any of these systems since the official release, and I don't know why. But I digress.
When I cleared my save when 1.3 was released, I spawned at LHS 3447. I cleared it again to see where else I could spawn, because I heard of this system before.
After 6 times in a row spawning in LHS 3447, I gave up trying, did one mission, killed 2 pirates, avoided 3 player interdictions in the process, took my free Eagle with a fuel scoop, and traveled 140 ly.
Even though there was several spawn points before, it doesn't seem to be random as I kept spawning in the same system. I can't think of any good, intelligent reason for this to happen. It should be random
