The core density is relatively high (and pressure and temperature are really high), the density in the outer regions (>99.99% of the volume) is low, giving a low average density.

If there is insufficient mass, there will be no fusion, because gravity will not be able to compress the material sufficiently. However, if you could introduce more mass, then the effects of gravity increases, compressing the gas (reducing the volume) in the process, and thus increasing the density of the material.

Could you please point me to someplace were I might find the equations for calculating this graduating density? Thanks.

This is given by the hydrostatic equilibrium.
