 Hi Loodog, on File:Densityhisto.jpg, it says that you were the original author. The file is used on List of United States cities by population. Herein lies the problem, the data is not referenced in that section of the article, and I've been trying to find the page where the data is derived from. Would you be able to help out with that? I appreciate all help! Thanks much and Happy New Year!
