100 amp sub panel wire size

I now have the 100 amp breaker installed in my load panel. I will run wiring from the load panel to a 100 amp sub-panel in an unground 80 schedule PVC. I believe I need to use #2 wire for the the hots and the neutral. If this is correct, then what size ground do I use? Number 6? The sub- panel will be 50 feet from the main load panel.

A 100 main circuit breaker gets #4 wire (NEC), Codes are set by the AHJ authority having jurisdiction.
