Looking for Webstat Resources

I find myself trying to find different resources to find stats on internet usage, what people are looking for, how many are online, etc. I've found a couple of sites that are good, but I need your help. I want to put together a page that has good stats available...and are updated. I'd really like to find stat pages on specific demographics. If you know of some sites that aren't listed below, please leave a comment or email me. I know there are more and I just can't find them! Thanks.
