The 2015 ACS data came out from the Census Bureau in mid-September and gave us lots to chew on for the state of North Dakota. The four counties reported in the 1 year data are Burleigh, Cass, Grand Forks, and Ward. All three counties gained population from 2014. Cass increased the most with 4,507 more people, while Burleigh increased by 2,488, Ward by 1,891, and Grand Forks increased by 778.
