Asians were the fastest-growing racial group in the United States from 2000-2010, growing by nearly 30 percent in most states, according to a new report by the U.S. Census Bureau released today: 

The population that identified as Asian, either alone or in combination with one or more other races, grew by 45.6 percent from 2000 to 2010, while those who identified as Asian alone grew by 43.3 percent. Both populations grew at a faster rate than the total U.S. population, which increased by 9.7 percent from 2000 to 2010.

This map, made with ArcGIS, visualizes that population with a dot density map. Each dot represents 3,000 residents per county:
