Look at the whole county (Mont.), also illegals are never officially counted. When NoVa cracked down on illegals where do you think they went?
I’m not arguing the point over the problem with illegals (since my area certainly has been), only just citing the figures here for the city itself. As for illegals not officially being counted, that is wrong, they are (for census purposes) officially required to be counted — I don’t actually believe they should be (or rather, to the point, if they are, that they should not count with respect to political representation, only legal citizens should).
