My high school has changed a lot since I graduated.

Here's the AJC school guide listing for my high school. I wish I had the same data for when I graduated in '98. All I have are rough approximations based on anecdotal evidence.
I do know my class had over 400 graduating seniors and over 2000 students enrolled in the school. This site indicates that the school had just 1374 students in the 2003-2004 school year. It also says that Hispanic students account for 13% of the student body, black students for 25%, and Other for 12%, which is just crazy. There wasn't a significant Hispanic portion of the student body population when I was there, and it was about even between black and white.
I also know that a lot of the administrative staff (principal, vice-principals, etc.) turned over just after I left, because my sisters were still going there.
