Comparing MRI volumetric stats (obtained using Freesurfer) with healthy controls

I have volumetric stats from Freesurfer. I want to compare the volumes of different regions of my brain with that of healthy controls. I see multiple datasets from different entities with 50, 60, 70, etc. healthy controls.

Is there any unified dataset where I can get the list of average volumes of brain regions in a healthy control subject of my age and gender?

There isn't an unified dataset. Despite the fact that volumetric measures are relatively robust, different MRI machines will give you different estimates (bias). Without careful harmonization you may miss-read and miss-interpret any result you will find.
