The study compared over 150 of the biggest U.S. cities across four categories: pollution, living conditions, infrastructure and consumer satisfaction. LawnStarter gathered public data on factors such as median air quality index, greenhouse gas emissions, the share of homes with signs of mice or rats, the number of unsheltered unhoused people per 1,000 residents, and tons of landfill waste per 100,000 residents.
To determine the rankings, LawnStarter calculated weighted scores for each city in each category and averaged the scores.
“These problems are unsightly, but they’re more harmful than we might realize," LawnStarter reported. “Air pollution, for instance, worsens lung cancer and increases our chances of heart disease and stroke.”
