No U.S. city ranks among the world's top 10 in quality of life

According to a ranking from The Global Liveability Index, the Austrian capital of Vienna enjoys the most optimal living conditions.

Vienna, Austria, is the best city to live in the world. This is stated in The Global Liveability Index 2023 by the Economist Intelligence Unit, a global business intelligence and market outlook entity belonging to The Economist Group. Austria's capital enjoys the best livability ranking, with a score of 98.4 out of 100.

The Economist Intelligence Unit's objective is to rank cities according to their living conditions. The entity calculated the liveability ratings based on five aspects: stability, health, culture and environment, education and infrastructure. Each of these categories is rated between 1 ("intolerable") and 100 ("ideal"). It then averaged and determined the final score for each city.

It should be noted that none of the 10 cities with the best livability index is in the United States. After Vienna, the Economist Intelligence Unit ranked Copenhagen, Denmark, with a score of 98.0; Melbourne, Australia, 97.7; Sydney, Australia, 97.4; Vancouver, Canada, 97.3; Zurich, Switzerland, 97.1; Calgary, Canada, 96.8; Geneva, Switzerland,, 96.8; Toronto, Canada, 96.5; Osaka, Japan, 96.0; and Auckland, New Zealand, 96.0.

On the opposite side are Douala, Cameroon, with a livability index of 46.4; Kiev, Ukraine, with 44.0; Harare, Zimbabwe, with 43.8; Dhaka, Bangladesh, with 43.8; Port Moresby, Papua New Guinea, with 43.4; Karachi, Pakistan, with 42.5; Lagos, Nigeria, with 42.2; Algiers, Algeria, with 42.2; Tripoli, Libya, with 40.1; and Damascus, Syria, with 30.7.

Two U.S. cities are among the biggest losers in the rankings

Two U.S. cities ranked among the world's most unliveable: Los Angeles and San Diego, two Californian cities governed by mayors who are members of the Democratic Party, Karen Bass and Todd Gloria, respectively.

With their liveability score stagnating, they both fell back in the ranking. Each of them dropped 17 places. Lack of safety and policies that provoke confrontation in society in Los Angeles and San Diego were reasons why they did not improve their score and failed to progress in their liveability index.
