50 Articles Needed

I need 50 quality articles about 50 different cities in the US - concerning the city's population to be precise. The articles need to be approximately 100 - 150 words long each and can contain such information as the city's population, metropolitan population, population density, population growth rate, population trends, demographic information, etc. (Needs to contain some such information, not all for each city) Articles require the following: - Flawless grammar/spelling - Quality, recent sources of academic quality (government websites, news websites, non-Wikipedia encyclopedias, etc) from varying locations (i. e. not all articles reference encyclopedia Britannica - one information source can be used for maximum of 7 articles). - URL is all that is required for a source - All numeric data should have something such as "(2010 data)" following it.
