This infographic from Busy Bee Cleaning Service takes data from the U.S. Environmental Protection Agency, the U.S. Census Bureau, and the American Housing Survey to develop a metric used to determine which metropolitan cities are the dirtiest.
Also, there's a lot that goes into what determines a city's ranking on this list. These can include factors like pests (including mice and cockroaches), litter, the population density, the amount of air pollution, and the nitrogen dioxide air pollution.
This infographic ranks the top 40 cities across the country!
