¹ Total sample size is the combined sample size from the 1999, 2000, and 2001 NSDUHs. ² Population Estimate is the simple average of the 1999, 2000, and 2001 population counts for persons aged 12 or older. The sum of the substate region population counts within a State may not exactly match the State population count listed in the table due to rounding.
