Mississippi dipped back into recession in 2011, with overall economic output shrinking 0.8 percent, according to federal figures released Tuesday.
Mississippi was one of only six states where the economy contracted last year, along with Alabama, Hawaii, Maine, New Jersey and Wyoming.
The state's gross domestic product, all the goods and services produced by the private and public sectors, fell to $84.3 billion.
That remained below the peak of $87.1 billion in 2007.
The figures are measured in 2005 dollars to account for inflation.
Mississippi recorded the lowest per capita economic output at $28,293 per person, compared to a national average of $42,070.
Mississippi performed worse than all but Wyoming. That state's economy contracted 1.2 percent.
North Dakota grew fastest at 7.6 percent, thanks to an oil boom.
