America's Dirty Secret
Here is a paradox hiding in plain sight on American streets. Between 2020 and 2025, the total quantity of litter along the nation's roadways and waterways fell by 34 percent. Cigarette butts — for decades the single most littered item in the country — dropped by 62 percent. By the numbers, America's streets are meaningfully cleaner than they were five years ago.
And yet: only 17 percent of Americans believe litter in their community has improved. Fifty-five percent say it feels about the same. Many would say it feels worse.
That gap between the data and the lived experience is not a trick of perception. It is an economic story — about what kinds of litter are growing, who bears the costs of disorder, why enforcement rarely works, and what it actually takes to make a city feel clean. The 2026 Keep America Beautiful National Litter Study, the most comprehensive assessment of its kind, gives us the numbers. Economics gives us the explanation.
The Free-Rider Problem, Scattered Across Every Block
Start with the most fundamental question: why do people litter at all?
The economic answer is not that litterers are bad people. It is that clean streets are a public good — non-excludable and non-rival, available to everyone regardless of who contributes to their upkeep. That structure creates a near-perfect free-rider problem. Every person who disposes of their trash properly bears a small private cost (the effort of finding a bin) while producing a diffuse public benefit (a slightly cleaner street). Every person who litters captures a private benefit (convenience) while imposing a tiny cost on everyone else. Individually rational; collectively ruinous.
The 2026 KAB public attitudes survey makes this mechanism visible at national scale. A remarkable 90 percent of Americans say it is their personal responsibility to help reduce litter. And yet 74 percent admit to having littered at some point in their lives, with 13 percent having done so in the past month. The gap between what people believe and what they do is not hypocrisy — it is the free-rider problem operating exactly as economic theory predicts.
The same survey found that people are significantly more likely to litter when they assume someone else will clean it up, and when no disposal option is nearby. Forty percent of self-reported recent litterers cited the absence of a trash or recycling bin as their primary reason. Fifty-eight percent cited pure convenience. This is the economics of marginal cost: when the cost of compliance rises — no bin in sight, full hands, nowhere obvious to put it — the rate of defection rises too.
The implication is important. Appealing to people's values, while not useless, runs directly against the incentive structure of a public good. What actually changes behavior is lowering the compliance cost — more bins, better placement, cleaner and more accessible infrastructure — or raising the cost of defection through credible enforcement. On both counts, American cities have a long way to go.
Why the Numbers Improve but the Streets Don't Feel Like It
The 34 percent aggregate decline in roadway and waterway litter is real — but it conceals a more complicated picture. Not all categories of litter are falling. Cardboard litter increased by 50 percent between 2020 and 2025, mirroring the explosion of e-commerce packaging. Litter from tires, tire treads, and vehicle debris grew by more than 36 percent. Construction and demolition debris is rising. These are precisely the types of litter that are large, visually intrusive, and concentrated along the commercial corridors and busy roads that urban residents see every day.
Meanwhile, the categories that drove the aggregate decline — cigarette butts, paper, plastic bottles — tend to be small. And small is the dominant mode of American litter: 84 percent of all litter items measure under four inches in length. The national count of 35 billion pieces of litter remaining across roadways, waterways, and coastal areas is composed overwhelmingly of tiny fragments that are individually invisible but collectively form the grim texture of a neglected public space.
There is also the matter of coastal litter, measured for the first time in this study. Coastal environments average 16,800 litter items per mile — compared to 2,204 per mile on roadways and 1,300 on waterways. These are the recreational spaces that shape Americans' felt sense of their environment. A beach or shoreline thick with small plastic fragments, foam pieces, and debris from upstream tells a different story than a clean roadway count.
35 billion pieces of litter remain across America's roadways, waterways, and coastal areas on any given day — even after a 34 percent reduction from 2020.
In short, the measures that are improving are not the ones most visible to daily urban life. The measures that are worsening — cardboard, vehicle debris, coastal accumulation — are exactly what people see, smell, and navigate around. The data is improving; the experience is not.
A Problem That Falls Hardest on Those Who Can Least Afford It
Litter is not distributed evenly. It accumulates where the infrastructure to manage it is thinnest, the enforcement is lightest, and the political leverage to demand better service is weakest — which is to say, in lower-income neighborhoods.
A peer-reviewed study of New York City's litter bin inventory found that census tracts with higher median household incomes have significantly more litter bins than lower-income neighborhoods (Overflowing Disparities, BMC Public Health, 2022). This is the infrastructure gap made literal: wealthier areas have more places to put trash properly, while poorer areas — where the KAB survey indicates littering rates are higher precisely because of infrastructure scarcity — have fewer. More foot traffic, fewer bins, less frequent pickup: the conditions for visible disorder are baked into the physical landscape of low-income urban space.
The feedback loop from there is punishing. Visible litter and disorder depress property values. Lower property values shrink the local tax base. A thinner tax base constrains the municipal sanitation budget. A squeezed sanitation budget means less pickup, less infrastructure, less enforcement — and more litter. The Keep America Beautiful organization estimates the national annual cost of litter prevention and management at over $10 billion, a burden disproportionately borne by municipalities with the least fiscal capacity to absorb it.
Urban economists and criminologists have long debated the "broken windows" theory — the idea that visible disorder like litter causes more serious crime and social decay. The causal claim has been contested: Northeastern University researchers found in a major meta-analysis that studies accounting for neighborhood income levels saw much weaker disorder-crime links than those that did not, suggesting poverty drives both disorder and crime rather than disorder driving crime. But even setting aside the causation question, the correlation between litter, disinvestment, and economic decline is real and self-reinforcing. As one analysis of Los Angeles put it: once people believe "this is just how the city is," it lowers expectations for both residents and government — making the cycle of disorder even harder to break.
Why Enforcement Is Broken — and What Actually Works
The intuitive policy response to littering is to fine people more. It almost never works — for a straightforward economic reason.
Standard deterrence theory holds that a rational agent will avoid an illegal act when the expected penalty (the fine multiplied by the probability of being caught) exceeds the private benefit. For littering, that calculation almost always favors littering. In New York City, fines range from $50 to $250. In Singapore, first-offense fines run $300 to $1,000, with potential jail time for repeat offenders. Toronto starts at $365. American fines are low — but the bigger problem is that the probability of being caught is close to zero. Most U.S. states require a law enforcement officer to witness the act before issuing a citation. With police departments treating littering as the lowest-priority enforcement matter, the expected cost of dropping a coffee cup on the sidewalk is functionally nothing. A research study of litter law enforcement in Pennsylvania and South Carolina concluded directly that higher fines are not considered a deterrent, and that community service and cleanup requirements outperform punitive fines.
What the KAB data show, though, is that targeted infrastructure and behavioral programs can produce large results where enforcement cannot. The 62 percent drop in cigarette butt litter since 2020 — far outpacing the one-to-three percentage point decline in smoking rates during the same period — was driven in substantial part by dedicated butt-disposal receptacles and clear, point-of-disposal messaging. Keep America Beautiful's Cigarette Litter Prevention and Recycling program achieves an average 50 percent reduction in cigarette butt litter in participating communities. The mechanism is simple economics: lower the cost of compliance. When a bin is right there, the rational calculus flips.
Cities that have sustained cleanliness over time tend to share three institutional features. First, sanitation budgets insulated from annual appropriations politics — not subject to the kind of mid-year $106 million slash that New York City executed in 2020, which immediately reduced litter basket pickup by 60 percent and eliminated highway sweeping. Second, dense, accessible disposal infrastructure distributed equitably across neighborhoods. Third — and most durably — social norms internalized from early education, which substitute for costly enforcement by making littering genuinely uncommon rather than merely formally prohibited.
What Norms Can Do That Fines Cannot (The Japan Lesson)
The sharpest international comparison is between Yokohama, Japan and Singapore — two wealthy, dense Asian cities, similar in income, opposite in their approach to cleanliness.
Singapore maintains clean streets through top-down enforcement: high fines, professional cleaning staff, heavy government expenditure. Japan achieves comparable or greater cleanliness through bottom-up norm internalization: cleaning is taught in schools as a civic virtue, volunteers outnumber paid sanitation workers in many neighborhoods, and the social cost of visibly littering is high. A study by Ong and Sovacool published in Resources, Conservation & Recycling found that Singapore spends millions annually on litter removal while Japan spends relatively little — because in Japan, citizens do the work voluntarily, because they believe it is their responsibility and their neighbors would notice if they did not.
This is not a cultural mystery impervious to policy. It is the outcome of deliberate institutional choices made over decades. Japan embedded cleanliness into the school curriculum. It designed neighborhoods so that cleaning one's immediate space (the street outside your shop or apartment) was a clear individual responsibility. It built a culture where the social cost of free-riding on public cleanliness — the shame, the neighbor's disapproval — exceeded the private benefit of convenience.
The United States, by contrast, is what researchers call a "loose-culture" country: social norms carry lower enforcement weight, deviations are less sanctioned, and the free-rider problem in public goods therefore operates with fewer natural checks. Americans overwhelmingly agree, in surveys, that littering is wrong and that reducing it is everyone's responsibility. But agreement is not the same as norm internalization — and the gap between the two is where 35 billion pieces of litter live.
Progress Is Possible — But Not Inevitable
The 2026 KAB study's headline finding — that litter is down significantly — is genuinely good news, and it deserves to be recognized as such. Coordinated programs work. Infrastructure investment works. Behavior change campaigns, when they are specific and tied to point-of-disposal infrastructure, work. The cigarette butt story is proof.
But the same study makes clear that progress is fragile. Municipal budgets are cut; programs disappear; gains evaporate. Cardboard and vehicle debris fill the void left by declining cigarette butts. Coastal environments accumulate litter faster than anyone is cleaning them up. And the neighborhoods that most need clean streets — that have the fewest bins, the least frequent pickup, the lowest property values and therefore the highest stakes — are the neighborhoods receiving the least investment.
The economics of litter point in a consistent direction. Clean streets are a public good, and public goods require deliberate institutional support to be maintained. That means sanitation budgets protected from the political cycle, equitable distribution of disposal infrastructure, enforcement redesigned around behavioral evidence rather than deterrence mythology, and — most ambitiously — investment in the social norms and civic culture that make the free-rider problem less tempting to solve in the cheapest possible way.
Clean cities are not wealthy cities. They are cities that have decided to act like the problem is solvable — and have built the institutions to prove it.
