Private school diversity

Today I was browsing the web page of a private elementary/high school that costs about $30,000 a year and features the diversity of its students in its promotional material and websites as a selling point. It reports that it does not discriminate on the basis of race, gender, national or ethnic origin, disability, or sexual orientation, and that 41% of its school population are "people of color." That's odd, the latest census reports that about 75% of the U.S. population is white, so how could this school not be selecting students on the basis of race? I'm not sure that the Columbus City Schools have that high a percentage of "diversity." There are lots of ways to recruit students, maybe they should be sending more mailings to white parents? Also, I wonder how many learning disabled children attend this school, or do they limit disabilities to those who can keep a very high grade point? Do they accept children who will not go on to college, but who will earn good livings servicing the automobiles of their graduates, or saving them when their home catches fire, or defend them at our borders? Just wondering about that word "diversity."
