You will notice that there is a large difference in the White and the Black percentages. I am not sure how you can account for this, but generally speaking, the demographics of an area will be mirrored in the Community High School.

Notice how the general demographics of the Population of Oakton mirror the General HS enrollment numbers. I am pretty sure that if you do the same comparisons of Langley, Madison, Westfield and Chantilly, the correlation between the populations demographics and the HS demographics will be very similar.
I am not sure what all of this means for South Lakes, but it is interesting.
