Is it appropriate to mention my cultural background?

Applying for Cambridge
I was going to write a tiny bit on my personal statement about my interest in sustainable urban planning in East Asia.
Would it be a good idea to mention my own personal connection? (I'm half Pakistani, half Filipino)
Or would that just be a waste of words...
Also, I heard that the number of non-white successful applicants has been increasing year on year, so I was wondering if it may be helpful (obviously they know where I'm from based on the rest of my application, but ykwim)
