The figures included in this short article are from the 2005 American Community Survey (ACS) released by the U.S. Census Bureau in late 2006. The 2005 ACS data set involves estimates based on surveys distributed to only a subset of the U.S. population and is thus problematic in some respects. This concise article is intended to provide basic 2005 demographic, educational and socioeconomic data related to Cambodian, Hmong, Lao and Vietnamese in the United States. It is not intended as a comprehensive explanatory research paper of factors underlying contemporary demographic, educational, and socioeconomic trends in these four ethnic communities. These topics should ideally be the focus of additional quantitative and qualitative research. Most of the figures used in this article are from the “Cambodian alone or in any combination,” “Hmong alone or in any combination,” “Lao alone or in any combination,” and “Vietnamese alone or in any combination population” profiles including in the 2005 ACS.
