According to the 2010 Census, the Asian population grew faster than any other race group in the United States between 2000 and 2010. This was observed for the population who reported Asian alone (increased 43 percent), as well as for the population who reported Asian alone or in combination with another race (increased 46 percent). The Asian population continued to be concentrated in the West, and the Chinese population was the largest detailed Asian group.

This report provides a portrait of the Asian population in the United States and discusses that population’s distribution at the national level and at lower levels of geography. It is part of a series that analyzes population and housing data collected from the 2010 Census.

The data for this report are based on the 2010 Census Redistricting Data (Public Law 94-171) Summary File, which was the first 2010 Census data product released with data on race and Hispanic origin, including information on the Asian population, and was provided to each state for use in drawing boundaries for legislative districts. Data for this report also come from the 2010 Census Summary File 1, which was one of the first 2010 Census data products to provide information on selected detailed groups, such as Asian Indians, Koreans, and Filipinos.
