(NewsNation) — Five U.S. cities are considered "impossibly unaffordable" when it comes to housing, placing them among the most expensive markets in the world, according to a new study.

Researchers at Chapman University and the Frontier Centre for Public Policy in Canada analyzed 94 major cities in eight countries and determined San Jose, California is the least affordable housing market in the U.S. The Silicon Valley metro was the fourth most unaffordable in the English-speaking world.

In fact, four of the top 10 least affordable housing markets on the list were in California: Los Angeles (5th), San Francisco (8th) and San Diego (10th). Honolulu, ranked sixth, was the only city outside the Golden State ranked near the top.
