The Panel on Research on Future Census Methods was formed to examine alternative designs for the 2010 census and to assist the Census Bureau in planning tests and analyses to help assess and compare the advantages and disadvantages of them. Designing the 2010 Census: First Interim Report, examines whether the auxiliary information that is planned to be collected (and retained) during the 2000 census could be augmented to help guide the Census Bureau in its assessment of alternative designs for the 2010 census.
