Massachusetts scored the second highest in the nation in Gallup’s Economic Confidence Index in 2013.

According to Gallup, Washington D.C. was the only area of the country to score positive; the rest of the areas on the list were in the negative territory. Massachusetts scored the least negative with an index score of -1, but it’s a vast improvement over 2012’s score of -13.

Although scores on Gallup’s Economic Confidence Index improved in most U.S. states in 2013, the index remained negative in all 50. Only the District of Columbia had a positive index. Indexes were least negative in Massachusetts, Minnesota and California. They were most negative in West Virginia, followed by Alaska.

The results, according to Gallup, are based on Gallup Daily tracking interviews with 178,071 national adults conducted from January through December 2013, and represent averages for the year. Gallup conducted interviews with at least 500 residents in every state and interviewed 1,000 or more in 41 states. In the District of Columbia, 462 interviews were conducted.

The Gallup Economic Confidence Index is a composite of Americans’ ratings of current U.S. economic conditions and their perceptions of the economy’s direction. The index has a theoretical maximum of +100 (if all respondents rate the economy "excellent" or "good" and say it is getting better) and a theoretical minimum of -100 (if all rate the economy "poor" and say it is getting worse).
