This data visualization takes a detailed look at annual percentage change in state population over the last decade and shows variation in growth patterns. Red hues indicate growth, and blue hues indicate decline.  In recent years, North Dakota and the District of Columbia have had the highest growth rates, in percentage terms, in the country. States such as Nevada and Arizona, fast-growers a decade ago, have had some moderation in their growth rates but the states continue to increase in population.
