The proportion of American adults who smoke cigarettes has hit a new low, new federal data show. And among those who do smoke, fewer are lighting up every day, and even they are smoking fewer cigarettes.

A national health survey conducted by the Centers for Disease Control and Prevention found that 17.8 percent of adults — or 42.1 million people — were “current cigarette smokers” in 2013. That’s the lowest percentage since the annual survey began keeping track in 1965, according to the authors of a study published Wednesday in the CDC’s Morbidity and Mortality Weekly Report.

But Americans still have a ways to go to meet the nation’s Healthy People 2020 target, the study notes. That target, set by the Department of Health and Human Services, aims to limit the adult smoking rate at no more than 12 percent.

Smoking is the leading cause of premature death in the United States, killing 480,000 Americans each year and costing the economy $289 billion in annual health costs and lost productivity, the report’s authors noted.

The data in the report come from the National Health Interview Survey, an in-person survey conducted every year with a representative sample of American adults who aren’t serving in the military or institutionalized. Participants were considered current smokers if they said they had smoked at least 100 cigarettes in their lifetime and at the time of the interview smoked some days or every day. (The surveyors didn’t attempt to verify smoking status by analyzing tobacco metabolites in blood or urine samples, but other studies have found that self-reports are accurate.)

The data show not only that fewer Americans are smoking cigarettes but also that the ones who are smoking are smoking less. The proportion of current smokers who are daily smokers fell from 80.8 percent in 2005 to 76.9 percent in 2013, researchers found. That translates to 32.4 million adults who smoke every day.

And even those daily smokers are smoking less. In 2007, daily smokers puffed on an average of 16.7 cigarettes per day. By 2013, that figure had dropped to 14.2.

Here’s another way to look at it: The proportion of daily smokers who smoked between 1 and 9 cigarettes each day grew from 16.4 percent in 2005 to 23.3 percent in 2013, and the proportion who smoked 10 to 19 cigarettes each day rose from 36 percent to 40.3 percent during the same period. As a result, the share of daily smokers who smoked 20 or more cigarettes per day dropped from 47.6 percent to 36.4 percent over those eight years.
