On a happiness ranking of all states in the country, residents self-reported Virginia 28th, D.C. 36th and Maryland 40th. The ranking is based on more than 1 million U.S. citizens reporting their life satisfaction levels.
Professor Andrew Oswald with the University of Warwick in the U.K. coauthored the paper in this month's journal of Science. He says certain factors could have played a part in the law ranking of D.C, Maryland and Virginia.
"The congestion, the high land prices, the commute to work and so on," says Oswald, played a role in the rankings.
Oswald says they compared what people said with what are considered "objective indicators," including the weather, public schools and local taxes and found a close correlation between the two sets of information.
The happiest state is Louisiana and the most unhappy is New York.
