Wyoming is the fourth-best state in the nation for retirement, according to a recent study by WalletHub.

Virginia, Florida and Colorado were the top three states to retire in, the study showed.

WalletHub, a personal finance company, evaluated all 50 states in three key categories: affordability, quality of life and access to health care. The study used data from various agencies, including the U.S. Census Bureau and the Centers for Disease Control and Prevention.

Kentucky was ranked the worst state for retirees, mainly due to its low quality of life scores and its relatively difficult access to health care.

LARAMIE, Wyo.—A recent Wyoming Truth survey of University of Wyoming juniors and seniors revealed that the majority of respondents intend to leave the state following graduation, a sign that “brain drain” is an ongoing issue plaguing the Cowboy State.
