Q to start my sociology project-what % of U.S.A.adult(over 21) smoke cigarttes?

Answer 1

According to the report of the 2002 National Health Interview Survey (NHIS),  in 2002, approximately 22.5% of adults were current smokers. the 2002 NHIS adult core questionaire was administered by personal interview to a nationally representative sample (n = 31,044) of the U.S. civilian, noninstitutionalized population aged >18 years; the overall survey response rate was 74.3%.

In 2002, an estimated 45.8 million adults (22.5%; 95% CI = ?0.6) were current smokers; of these, an estimated 37.5 million (81.8%) smoked every day, and 8.3 million (18.2%) smoked some days

The prevalence of smoking was higher among men (25.2%) than women (20.0%) and inversely related to age, from 28.5% for those aged 18--24 years to 9.3% for those aged >65 years
