Tobacco Use Supplement-Current Population Survey


The Tobacco Use Supplement to the Current Population Survey (TUS-CPS) is an NCI-sponsored survey of tobacco use that is administered as part of the US Census Bureau's Current Population Survey. The Centers for Disease Control and Prevention (CDC) was a co-sponsor with NCI from 2001-02 through 2006-07.

Data Years Available: 
Mode of Collection: 
The tobacco supplement is person level. It consists of both self-responses and proxy responses. According to the instructions on the survey questionnaire, if the household is eligible for the supplement, the interviewer attempts to interview each individual (18 years or older) in the household, with respect to the tobacco supplement questions. Proxy responses are acceptable only in certain situations (4th call back, respondent will not return before closeout, the household is getting irritated.) Note: In order for an individual to be eligible for the supplement, the individual’s basic CPS questionnaire must have been completed.
Selected Content: 
The TUS-CPS is a key source of national, state, and sub-state level data from US households regarding smoking, use of tobacco products, and tobacco-related norms, attitudes, and policies. It uses a large, nationally representative sample that contains information on about 240,000 individuals within a given survey period.
Population Covered: 
Civilian, non-institutionalized population ages 18 years and older (data for the 1992-2006 TUS-CPS are for persons 15 years and older).

The basic CPS sample is selected from multiple frames using multiple stages of selection. The sample design is state-based, with the sample in each state being independent of the others. One person generally responds for all household members. Employment information is collected on the job held in the reference week, defined as the 7-day period, Sunday through Saturday, that includes the 12th of the month. Labor force data are published only for persons aged 16 and older; no upper age limit is used. Full-time students are treated the same as nonstudents. The March CPS supplement is expanded to include Armed Forces members living in a household that includes at least one civilian and additional Hispanic households that are not included in the monthly labor force estimates. The additional Hispanic sample is drawn from the previous November's basic CPS sample. All CPS data files are weighted; information on weighting procedures is available in the Technical Documentation section of the CPS website.
Census Bureau staff conducts the Tobacco Use Supplement (TUS) to the Current Population Survey (CPS) periodically. As of 2011, supplements were sponsored in May 2010, August 2010 and January 2011; in May 2006, August 2006 and January 2007; in February, June and November 2003; in June 2001, November 2001 and February 2002; in September 1998, January 1999, and May 1999; in September 1995, January 1996, and May 1996; and in September 1992, January 1993, and May 1993. An abbreviated TUS was also conducted in January 2000 and May 2000.

Response Rates and Sample Size: 

• State sample sizes range from 2,100 for the District of Columbia to 18,700 for California;
• The national sample size is approximately 240,000 individuals within a given survey period.
O For the 2010-11 data the sample size is 229, 456 (January 2011 82,736; August 2010 62,540; May 2010 84,180)
•About 64% of respondents complete the TUS-CPS by telephone and 36% complete it in person; and
•Mostly self-reports (about 20% are by proxy for a few measures of use).
Since the basic CPS nonresponse rate is a household-level rate and the Tobacco Use supplement nonresponse rate is a person-level rate, we cannot combine these rates to derive an overall nonresponse rate. Nonresponding households may have fewer persons than interviewed ones, so combining these rates may lead to an overestimate of the true overall nonresponse rate for persons for the Tobacco Use supplement. In order for an individual to be eligible for the supplement, the individual’s basic CPS questionnaire must have been completed. The TUS response rate is calculated as the percentage of those who completed the TUS to those who were eligible to complete it.
• For the May 2010 basic CPS, the household-level nonresponse rate was 7.6 percent.
• The person-level nonresponse rates for the Tobacco Use supplement were 17.8 percent for the total (self and proxy responses) and 37.7 for self-response only.
