DU = dwelling unit.
NOTE: To compute the pooled 2007-2008 weighted response rates, two samples were combined, and the individual year weights were used for the pooled sample. Thus, the response rates presented here are weighted across 2 years of data rather than being a simple average of the 2007 and 2008 individual response rates. The 2007-2008 population estimate is the average of the 2007 and the 2008 population.
NOTE: The 2007-2008 data may differ from data published prior to 2012 due to updates (see Section 1.5 of the report on State Estimates of Substance Use and Mental Disorders from the 2009-2010 NSDUHs).

NOTE: To compute the pooled 2008-2009 weighted response rates, two samples were combined, and the individual year weights were used for the pooled sample. Thus, the response rates presented here are weighted across 2 years of data rather than being a simple average of the 2008 and 2009 individual response rates. The 2008-2009 population estimate is the average of the 2008 and the 2009 population.
NOTE: The 2008-2009 data may differ from data published prior to 2012 due to updates (see Section 1.5 of the report on State Estimates of Substance Use and Mental Disorders from the 2009-2010 NSDUHs).

NOTE: Computations in this table are based on a respondent's age at screening. Thus, the data in the Total Responded column(s) could differ from data in other NSDUH tables that use the respondent's age recorded during the interview.
NOTE: To compute the pooled weighted response rates, the two samples were combined, and the individual-year weights were used for the pooled sample. Thus, the response rates presented here are weighted across 2 years of data rather than being a simple average of the individual response rates. The population estimate is the average of the population across the 2 years.
NOTE: The 2007-2008 and 2008-2009 data may differ from data published prior to 2012 due to updates (see Section 1.5 of the report on State Estimates of Substance Use and Mental Disorders from the 2009-2010 NSDUHs).

NOTE: Computations in this table are based on a respondent's age at screening. Thus, the data in the Total Responded column(s) could differ from data in other NSDUH tables that use the respondent's age recorded during the interview.
NOTE: To compute the pooled weighted response rates, the two samples were combined, and the individual-year weights were used for the pooled sample. Thus, the response rates presented here are weighted across 2 years of data rather than being a simple average of the individual response rates. The population estimate is the average of the population across the 2 years.
NOTE: The 2007-2008 and 2008-2009 data may differ from data published prior to 2012 due to updates (see Section 1.5 of the report on State Estimates of Substance Use and Mental Disorders from the 2009-2010 NSDUHs).
