My HS would look exactly like the district it was in. There were no private options, there was no home schooling, there was no option to go to the other HS in the County. Now one of my son's, ranked by some as a top 10 public in US but looked more like a private, looks more like yours above. Over represented Asian & prob international. But not represent US in terms of education appititude to get in or going out. ~1/3rd every year made National Merit, almost everyone accepted & attended college of their choice. So depends on what diversity one is trying to represent.
