"The U.S. population rose by just 0.72% in 2013, the lowest growth rate in more than 70 years. Not only has the country become less-attractive to immigrants than in years past, with net immigration down from nearly 1.2 million as of 2001 to 843,145 last year, but also the U.S.'s domestic birth rate has dropped to a multi-decade low.
While the population of most of the country's metro areas grew at a low pace in recent years, in a small number of metro areas the population actually shrank. Looking at the most recent years, the U.S. population rose by just 2.4% between April 2010 and July 2013, but in 30 metro areas the population shrank by at least 1%. The population in Pine Bluff, Arkansas, fell a nation-leading 4.4% in that time. Based on recently released U.S. Census Bureau estimates, 24/7 Wall St. examined the cities with shrinking populations."
