New figures show that Mississippi's economy grew by 1.6 percent in 2013.
Gross domestic product numbers released Wednesday by the federal Bureau of Economic Analysis try to measure all of the economic output of each state.
Mississippi's 2013 growth rate was below the national average of 1.8 percent, and ranked 29th among the 50 states.
Growth slowed markedly from 2012, when Mississippi's economy expanded by 3.5 percent, the best in the Southeast and one of the best in the nation.
The biggest contributors to growth in Mississippi last year came from construction and making non-durable goods such as paper.
Though the state's $105 billion economy slowed, it outperformed Louisiana, Alabama and Tennessee, lagging Arkansas.
Mississippi retained the lowest per capita gross domestic product of any state, at $32,421 per person.
