Question

In 2009, 24.3% of the U.S. population are under 18 years old. Choose one American at random. What is the probability that the American is 18 years old and over?

Answer 1

In the United States, the widespread use of tobacco began more than a century ago, and the epidemic of tobacco-caused diseases and premature mortality associated with tobacco use has continued to the present day. The purpose of the current chapter is to document key patterns and trends in tobacco use in the United States among youth (12–17 years of age), young adults (18–25 years of age), and adults age 26 years of age or older. The chapter indicates overall progress in the United States, but describes the persistence of a high prevalence of tobacco use among segments of the population.
