From the Summary:
Texas gained more people than any other state between April 1, 2010, and July 1, 2011 (529,000), followed by California (438,000), Florida (256,000), Georgia (128,000) and North Carolina (121,000), according to the latest U.S. Census Bureau estimates for states and Puerto Rico. Combined, these five states accounted for slightly more than half the nation’s total population growth.
“These are the first set of Census Bureau population estimates to be published since the official 2010 Census state population counts were released a year ago,” said Census Bureau Director Robert Groves. “Our nation is constantly changing and these estimates provide us with our first measure of how much each state has grown or declined in total population since Census Day 2010.”
The United States as a whole saw its population increase by 2.8 million over the 15-month period, to 311.6 million. Its growth of 0.92 percent between April 1, 2010, and July 1, 2011, was the lowest since the mid-1940s.
“The nation’s overall growth rate is now at its lowest point since before the baby boom,” Groves said.
California remained the most populous state, with a July 1, 2011, population of 37.7 million. Rounding out the top five states were Texas (25.7 million), New York (19.5 million), Florida (19.1 million) and Illinois (12.9 million).
