The U.S. Census Bureau says Michigan and Rhode Island were the only states that lost population in its latest estimate released today.
The report covers the 12 months ending in July.
The Census estimates that Michigan's population fell about 0.3 percent from last year's 10.1 million -- a drop of 30,500.
It says Rhode Island's population fell 0.4 percent.
The report also says Louisiana has regained part of the population it lost in Hurricane Katrina.
The fastest-growing states continue to be in the Rocky Mountain region and the Southeast.
Nevada's population rose 2.9 percent to 2.6 million, while Arizona's rose 2.8 percent to 6.3 million.
