North Dakota saw the biggest one-year jump in population, growing 2.28 percent. Only seven states saw their populations dip in the past year, with West Virginia leading the fall with a 0.25 percent overall drop. Shale-rich North Dakota up and coal-filled West Virginia down? Guess that shouldn't have surprised anyone following the energy sector. Keep in mind though this data only goes through July 1, 2015, and oil-rich states haven't had the best run in the quarters since.
Trump supporters, hold your ears: Some of the rise in the U.S. population last year was due to international migration. According to Census bureau data, net international migration in the U.S. as a percentage of total 2014 population was 0.36 percent in the 12 months ended July 1, 2015, with Hawaii more than double that rate at 0.71 percent. A total of seven states - New York, Florida, Massachusetts, New Jersey, Connecticut, Maryland and Hawaii - saw net international migration of more than 0.5 percent of their total populations. West Virginia and Montana saw the smallest inflow of new international residents, each with just 0.07 percent. No states ended the one-year period with net outflow abroad.
