Miners and food service workers have something in common: They both like to smoke. Teachers and business professionals, however, are among America's least likely smokers. Welcome to the new "collar-color divide," says John Gever at ABC, in which white-collar workers are much less likely to smoke than their blue-collar counterparts. Those are among the findings in a new study by the Centers for Disease Control and Prevention, which from 2004 to 2010 interviewed more than 113,000 Americans about smoking. Here, a look at more of the conclusions, by the numbers:

Percentage of U.S. adults who smoked regularly in 2010, according to the CDC 

Percentage of U.S. adults who smoked regularly in 2005

$193 billion
Annual cost associated with lost productivity and health care for smoking-related illnesses, according to Reuters

Percentage of mining workers who smoke. The industry sits atop the CDC's rankings. And remember, says Gever, workers are "already at risk for respiratory diseases because of their occupational exposures." 

Percentage of food service workers who smoke — tied with miners atop the CDC's list

Percentage of construction workers who smoke

Percentage of education workers who smoke — the lowest number on the CDC list

Percentage of business management workers who smoke

Percentage of finance and insurance workers who smoke

Percentage of "health care and social assistance" workers who smoke

Percentage of Americans with no high school diploma who smoke

Percentage of Americans with a bachelor, master, or other graduate degree who smoke

Percentage of white Americans who smoke — the highest rate of any ethnic group

Percentage of black Americans who smoke

Percentage of 18- to 24-year-olds who smoke — the highest rate of any age group

Percentage of those 65 and older who smoke — the lowest rate of any age group. In our "post-Mad Men world," Gever says, higher smoking rates are associated with "being poor or near-poor, uninsured, white, young, and male."
