States with a highly educated populace and higher taxes on cigarettes have fewer smokers, according to a new Gallup study of poll data.
The study found that one out of five American adults smoke, a number that has held relatively steady in recent years. Utah had the fewest smokers, at just 13 percent, while Kentucky and West Virginia tied for first place at 31 percent.
The South and Midwest dominated in smoker-heavy states. Besides Kentucky and West Virginia, Tennessee, Indiana, Arkansas, Missouri, Ohio, Louisiana, South Carolina and Alabama all had populations in which 25 percent or more people smoked. States that were under the national smoking average of 21 percent included: California, Idaho, Montana, the District of Columbia, New Jersey, Minnesota, Hawaii, Massachusetts, Arizona and Maryland.
Higher rates of smoking correlated with lower rates of formal education, according to the Gallup organization. West Virginia, Kentucky, Arkansas, Indiana, Tennessee and Oklahoma, for example, are all states where fewer than 25 percent of residents have college degrees. Massachusetts, Connecticut, Maryland, New Jersey and the District of Columbia, all areas with high rates of education, had some of the lowest rates of smoking.
Cigarette taxes are also associated with low smoking rates, though it’s not clear whether taxes discourage smoking or whether states with fewer smokers are more likely to pass high cigarette taxes. In states where smoking was well above average, the average state cigarette tax was $0.66 a pack. In average states, it was $1.59, and in below-average states, it was $2.02.
States that discourage smoking with regulations against smoking in public places also had lower smoking rates.
Questions 29 to 31 are based on the passage you have just heard.

31. What can be inferred from the passage?
