Out of 51 slots, California ranks No. 46 on the happiness scale. Surprisingly, New York and California do badly in the happiness ranking. Researcher Andrew Oswald of the University of Warwick in Coventry, England, says, "Many people think these states would be marvelous places to live, but the problem is that if too many individuals think that way, they move into those states, and the resulting congestion and house prices make it a non-fulfilling prophecy." So where is the No. 1 place brimming with happiness, you ask? Louisiana.
