Los Angeles, New York City and Detroit have been identified as the three North American cities with the lowest quality of life.
The results come from Numbeo’s Northern America Current Quality of Life Index, which assessed 73 cities in the United States and Canada using factors including safety, living costs and pollution.
Numbeo, the world’s largest crowd-sourced online database, compiled the rankings from its data and user surveys.
Los Angeles ranked last overall, with New York City in second-to-last place and Detroit third from the bottom.
Los Angeles recorded the highest levels of pollution and the worst traffic commute in the rankings. It also had the fourth-worst climate score.
New York City had the worst property price-to-income ratio. It also ranked second-last for both cost of living and purchasing power, with only Honolulu, Hawaii, scoring lower in those categories.
Detroit ranked worst for safety and second-worst for pollution. Its traffic commute was also the fourth-worst among the cities surveyed.
The results broadly reflect the challenges associated with each city’s reputation: Los Angeles is often linked to congestion and smog, New York City to its steep prices, and Detroit to crime and urban decay.
