Not one U.S. city ranks in the world's top 30 for its quality of living, according to Global consulting firm Mercer.
Vienna snagged the top spot for the 10th year in a row followed by Zurich at No. 2, and Auckland, Munich, and Vancouver tied for third.
Mercer assesses 450 cities around the world and ranks 231 based off factors including crime levels, personal safety, public services and transportation, political and social environment, recreation, housing, education, economy, and medical and health considerations.
San Francisco topped all U.S. cities at No. 34, followed by Boston (36), Honolulu (27), and New York (44).
All U.S. cities fell in the ranking with the exception of New York as crime rates fell in the city. Detroit came in last at 231.
Western Europe dominated Mercer's new safety ranking with Luxembourg at the top of the list.
"Companies looking to expand overseas have a host of considerations when identifying where best to locate staff and new offices," said Ilya Bonic, Senior Partner and President of Mercer's Career business.
"The key is relevant, reliable data, and standardized measurement, which are essential for employers to make critical decisions, from deciding where to establish offices to determining how to distribute, house, and remunerate their global workforces."
