New research shows the Dakotas have the fastest growing Hispanic population in the U.S. Pew Research Center says Hispanics have played a significant role in driving U.S. population growth over the past decade. They say several states with Hispanic populations of less than 100,000 had some of the fastest increases from 2010 to 2019. North Dakota saw its Hispanic population more than double with a 129% increase to 31,500 in 2019. It is the fastest growth of any state. South Dakota is second, up 66% to 37,400. However, South Dakota and North Dakota still have the smallest Hispanic populations in the country, as well as the youngest by median age. In South Dakota, that median age for the Hispanic population is 23. In North Dakota, it’s 24.
