In September 2005, the Governor of Guam named the Bureau of Statistics and Plans (BSP) as the liaison agency for the 2010 Census. Through a cooperative partnership with the U.S. Census Bureau, the Bureau of Statistics and Plans established Guam’s 2010 Census Interagency Committee in February 2006. Comprised of representatives from the data user community including the government, business, academic, private and non-profit sectors, the purpose of the Committee is to address issues related to the planning of the 2010 Census for Guam.

In May 2006, representatives from the U.S. Census Bureau met with members of the Interagency Committee to begin formal discussions and planning for the 2010 Census for Guam. At the meeting a preliminary timeline of some of the Committee activities in preparation for the Census was presented.
