I am trying to understand the relationship between Page Outs and Swap Used as displayed in Activity Monitor. Currently, Activity Monitor shows:
Page outs: 1.6 MB
Swap used: 8.1 MB
How can there be more swap used than the amount paged out?

My understanding is this:
OS's are getting smart about how they choose what and when to to page in/out. So the operation counts may not be the same, and the swap space may perhaps be in use without there being page outs.
Unless of course I'm backwards on what a page-in/page-out operation is. In which case your question makes perfect sense.
