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.
Growth for the 12 months ending July 1 was 0.71% or just under 2.3 million people, according to figures released Monday by the U.S. Census Bureau. In 2012, the U.S. population grew at a 0.75% rate.
Only two states - Maine and West Virginia - lost population. North Dakota, buoyed by an ongoing oil boom, once again proved the fastest-growing state, rising 3.1%, or more than four times the national rate. Close behind: Washington, D.C., which grew 2%, to 646,449.
Both North Dakota and D.C. are still comparatively tiny, appearing in the bottom five by total population.
Meanwhile, a long-awaited milestone will have to wait another year: Population watchers expected Florida to surpass New York for the first time, but it didn't happen. New York, which supplies many snowbird retirees to the Sunshine State, still has a slight advantage over Florida as third most-populous state, with about 98,000 more residents. But Florida, the figures show, is growing more than three times as quickly as New York.
California and Texas remain No. 1 and 2, respectively, with the largest populations.
