We ranked 87 of the biggest U.S. cities from dirtiest (No. 1) to cleanest (No. 87) based on their overall scores (out of 100 possible points), averaged across all the weighted metrics listed below.

We began with an initial sample comprising the 200 biggest U.S. cities. We then eliminated the cities — 113 total — lacking data for more than 10% of the total metrics in a single category.

The 87 cities that remained in our sample were then scored and ranked only on the metrics for which data were available. In most cases, a city lacked data for only one out of 23 total metrics and was limited to two maximum for the fairest possible comparison:

  • Median Air Quality Index
  • Presence of Water Quality Violations
  • Greenhouse-Gas Emissions (Metric Tons CO2e)
  • Annual Excess Fuel Consumption (Gallons per Auto Commuter)
  • Population Density (Residents per Square Mile)
  • Share of Overcrowded Homes
  • Share of Homes with No Kitchen Facilities
  • Share of Homes with No Plumbing Facilities
  • Share of Homes with Mold in Last 12 Month
  • Share of Homes with Signs of Mice or Rats in Last 12 Months
  • Share of Homes with Signs of Cockroaches in Last 12 Months
  • Share of Homes with Sewage Disposal Breakdowns in Last 3 Months
  • Unsheltered Homeless Rate (per 1,000 Residents)
  • Tons of Waste in Landfills per 100,000 Residents
  • Rating of State Waste Regulations and Measures
  • Refuse and Recycling Collectors per 100,000 Residents
  • Share of Roads in Poor Condition
  • Alternative-Fuel Stations per 100,000 Residents
  • Number of Junk Yards
  • Share of Residents Who Find City Dirty and Untidy
  • Share of Residents Dissatisfied with Pollution
  • Share of Residents Dissatisfied with Garbage Disposal
  • Share of Residents Dissatisfied with Greenery and Parks
