Idiom - Disparity __

<p>"Disparity of" or "Disparity in"?</p>

<p>The latter.</p>

<p>Either. A quick Google search gives me:
Economic disparities between different regions of the country
The great disparity of weight between the sun and the planets</p>

<p>Never felt "disparity of" sounded right though. But after viewing JP8000 post, I stand corrected.</p>
