Census director Robert Groves says the South and West continued their strong population growth over the last decade. 
 
 The total national count was 308,745,538, representing the slowest growth over the last decade since the Great Depression. 
 
 Groves spoke at a briefing announcing 2010 census results. He says the South had the fastest growth since 2000, at 14.3 percent. The West was close behind at 13.8 percent. 
 
 The Northeast had 3.2 percent growth while the Midwest had 3.9 percent. 
 
 The state with the largest population growth was Nevada with 35.1 percent. Michigan was the only state with a decline, at 0.6 percent. ||||| The U.S. population reached 313.9 million on July 1, a 0.75% increase in the past year.

 The nation's population is growing at near historic lows 
 
 The nation's population growth remains near historic lows as it struggles to recover from the Great Recession, new Census estimates show. 
 
 The U.S. population reached 313.9 million on July 1, a 0.75% increase or 2.3 million gain in one year. 
 
 "Pretty anemic," says Robert Lang, urban affairs professor at the University of Nevada-Las Vegas. "You see the impact of the recession and reduced immigration into the U.S. We're not on pace to grow even 10% over the decade." 
 
 The population numbers also show that the oil boom in North Dakota has sparked a people boom that made the state the fastest-growing since 2011 -- 2.2% or three times the national rate.

 Former boom states such as Nevada and Arizona continue to grow but at a much slower pace than before the 2007-09 recession.

 The estimates show the effects of an aging population, as the oldest Baby Boomers turned 66 this year and birth rates and immigration continue to decline. 
 
 Two states -- Rhode Island and Vermont -- lost population, largely because young people are leaving and few immigrants are arriving. Maine became the second state after West Virginia to experience more deaths than births -- both states with aging populations and low birth rates. 
 
 Florida continues to recover from a bad period when more people were leaving than moving in. Since July 1, 2011, the state attracted a net 200,000 people from other states and abroad. 
 
 "It looks like some of the Sun Belt boom-then-bust states are coming back," says William Frey, demographer at the Brookings Institution. "Florida continues its in-migration. ... Arizona is showing increased in-migration and Nevada is showing a flip from out to in." 
 
 Many states with strong diversified economies like North Carolina and Colorado are showing new strength. Texas gained the largest number of people -- 427,400. 
 
 "There is some evidence of a national recovery," Lang says. "Despite the recession, we're seeing the same patterns as the last decade, albeit slower growth across the board. The South and the West are growing the fastest." 
 
 High-flyers such as Nevada and Arizona are no longer leading the Western boom and the growth is more equally spread across the region, he says. 
 
 The numbers also show: 
 
 Northeastern and Midwestern states where population losses slowed when the recession kept people from moving are seeing their losses grow again. Among them: Illinois, Ohio, New York, Michigan, Missouri and Indiana. 
 
 California, which remains the most populous at 38 million, lost 45,000 people to other states but saw nearly three times as many immigrants arrive. 
 
 Georgia moved into eighth largest by bumping Michigan. And Arizona pushed past Indiana into 15th. Georgia and Arizona grew by more than 20% since 2000 while Indiana gained only 8% and Michigan declined. 
 
 Both West Virginia and Vermont slipped a notch. Nebraska topped West Virginia for 37th and the District of Columbia, counted as a state, topped Vermont for 49th place.

– Drumroll, please: The final tally is in, and the total US population is 308,745,538, the 2010 census finds. The South’s population has grown the fastest in the US since 2000, at 14.3%; the West was the runner-up, growing 13.8%. But overall, the population has expanded at its slowest since the Great Depression, the AP reports. The Northeast grew 3.2% and the Midwest grew 3.9%. Every state but Michigan (whose population declined 0.6%) saw growth, with Nevada expanding the fastest at 35.1%. The census was successful, the commerce secretary said at a press conference—and it came in almost $1.9 billion under budget, thanks to high participation and good management. Some 74% of households responded to questionnaires, about the same rate as in 2000.
