Here in an interesting essay about a gentleman who is living in the Packard Plant. I wonder how common this is? Right after the count from Census 2010 was released, Mayor Bing spoke of challenging the count so as to adjust for net undercount. Nothing ever came of that but the Census Bureau regulations made it very difficult for local governments to challenge their counts.
