Census 

I noticed you have reverted some population numbers citing no source.  While they definitely need a source, the census numbers are available at http://factfinder2.census.gov.  Rather than revert to old, outdated information, why not simply add the new source?  It's going to be a generic source anyway because the new FactFinder2 site doesn't allow you to bookmark the pages, so you have to find the page you want every time.  As for the New Albany article, I'm not sure what the problem is with either source you removed.  "ThisWeekNews" is a local newspaper website for that area (see Contact Us); it's not like city-data.com or another site that merely collects stories or data from somewhere else, so it seems to fit reliability to me.  Interestingly enough, if you go to the bottom of the main page for that site, there is also a link to county-level census data from the Columbus Dispatch.
