When I was in graduate school, we had a guest speaker who was a diversity consultant come give a talk and ran us through one of the example exercises they do for clients. It basically involves everyone standing in a conference room, on one side of a line, and the diversity consultant standing on the other side. They iteratively make statements relating to personal attributes or experiences and anyone that chooses to identify with that statement step over the line briefly before returning back to the group (either before the next statement or not).

For example, the first statement might be "I have served in the military" and veterans that don't mind being known for their military experience can step over the line. Other statements might be "I am the first person in my family to attend college", "I have questioned my sexuality", "I was raised in an upper class family", "I am vegetarian", "I am a recovering addict", ... etc.

It's a good exercise for showing both the things people have in common as well as the breadth of experiences that might exist in a group.

Interestingly, though I've never seen that exercise performed in an actual company in the twenty years since...
