USA Today: The Population of the USA is Growing at a Slow Rate
"An aging Baby Boomer population and slower immigration combined for nearly stagnant U.S. population growth in 2013 as the total number of residents inched up even more slowly than the previous year.
New figures released Monday by the U.S. Census Bureau show that growth for the 12 months ending July 1 was 0.71%, or just under 2.3 million people."
