State-level trends in urban-rural differences in cigarette smoking in the United States
Using 2018–2024 Behavioral Risk Factor Surveillance System data, this study reveals that rural adults in the United States consistently exhibit higher cigarette smoking rates than urban adults across most states, with disparities persisting or widening over time despite adjustments for demographic and educational factors.

Imagine the United States as a giant, sprawling neighborhood where some houses sit right next to each other in busy city centers, while others are scattered far apart in quiet, open country. For decades, scientists have been watching a curious trend in this neighborhood: people living in the quiet country spots seem to smoke more cigarettes than their neighbors in the bustling cities. This isn't just a small difference; it's a growing gap. Think of it like a race where the city runners are slowing down their smoking habit, but the country runners are either keeping their pace or slowing down much more slowly. This matters because smoking is a major cause of serious health problems, like lung cancer. If the gap keeps getting wider, it means the people in the country are carrying a heavier health burden than those in the city, and understanding why this is happening is the first step to fixing it.
This paper acts like a giant, state-by-state detective story, zooming in on every single state in the US to see exactly how this smoking gap has changed between 2018 and 2024. The researchers used a massive survey tool called the Behavioral Risk Factor Surveillance System (BRFSS), which is like a giant, annual census that asks hundreds of thousands of adults about their health habits. They didn't just look at the raw numbers; they played a game of "what if." First, they looked at the raw difference between city and country smokers. Then, they asked, "Is this just because country people are older, or have less schooling, or are a different race?" They built a series of mathematical models to strip away these factors one by one, like peeling layers off an onion, to see if the "country" factor itself was still the reason for the smoking.
Here is what the investigation found: The gap is real, and it's stubborn. In the vast majority of states—about 88% to 90% depending on how you count—people living in rural counties had higher odds of smoking than those in urban counties. Even after the researchers adjusted for age, sex, race, and education, the rural residents still smoked more in most places. In fact, in about 60% of the states, the difference remained significant even after accounting for education. This suggests that while demographics play a part, they aren't the whole story; something else about living in the country is keeping smoking rates higher.
The most surprising part of the story is how the gap is changing over time. The researchers found that in 14 specific states, the gap between city and country smokers is actually getting wider. It's not that country smoking is skyrocketing; rather, city smoking is dropping faster than country smoking. Imagine two people walking down a hill: the city walker is sprinting down, while the country walker is strolling slowly. The distance between them is growing. In states like Arizona, Wisconsin, and Montana, the odds of smoking for city dwellers dropped significantly year after year, but for their rural neighbors, the decline was much slower or didn't happen at all.
The paper explicitly rules out the idea that this is just a numbers game of who is older or less educated. While those factors explain some of the difference, they don't explain the majority of it, and they certainly don't explain why the gap is widening in those 14 states. The authors suggest that this points to other forces at play, possibly related to how tobacco control policies (like smoke-free laws or taxes) are enforced differently in rural areas compared to cities. They found that no state managed to shrink the gap during this time period. Instead, the trend suggests that without targeted help, the rural areas are being left behind in the fight against smoking. The study concludes that we need to look closely at what makes rural life different from city life regarding smoking, because the usual explanations don't fully solve the mystery.
