Here's how LawnStarter determined its rankings of the dirtiest cities in the U.S.:

"For each of the 500 biggest U.S. cities, we then gathered data on each factor from the sources listed [on the site]. We eliminated 197 cities lacking sufficient data in a single category, resulting in a final sample size of 303 cities. Finally, we calculated scores (out of 100 points) for each city to determine its rank in each factor, each category, and overall. A city's Overall Score is the average of its scores across all factors and categories."
