NOTE: For Substate Region definitions, see Section D.
NOTE: To compute the pooled 2004-2006 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 2004, 2005, and 2006 individual response rates.
NOTE: The total responded column represents the combined sample size from the 2004, 2005, and 2006 NSDUHs.
NOTE: The population estimate is the simple average of the 2004, 2005, and 2006 population counts for persons aged 12 or older. Due to rounding, the sum of the substate region population counts within a State may not exactly match the State population count listed in the table.
DU = dwelling unit.
