NOTE: For Substate Region definitions, see Section D.
NOTE: To compute the pooled 2006-2008 weighted response rates, the three samples were combined, and the individual-year weights were used for the pooled sample. Thus, the response rates presented here are weighted across 3 years of data rather than being a simple average of the 2006, 2007, and 2008 individual response rates.
NOTE: The total responded column represents the combined sample size from the 2006, 2007, and 2008 NSDUHs.
NOTE: The population estimate is a projection from Claritas that is the simple average of the 2006, 2007, and 2008 population estimates for persons aged 12 or older. Because of rounding, the sum of the substate region population estimates within a State may not exactly match the State population estimates listed in the table.
DU = dwelling unit.
