This guide addresses effective responses to the problem of graffiti — the wide range of markings, etchings and paintings that deface public or private property.† In recent decades, graffiti has become an extensive problem, spreading from the largest cities to other locales. Despite the common association of graffiti with gangs, graffiti is widely found in jurisdictions of all sizes, and graffiti offenders are by no means limited to gangs.
† Although graffiti is also found within public or private property (such as in schools), this guide primarily addresses graffiti in places open to public view.
Because of its rising prevalence in many areas — and the high costs typically associated with cleanup and prevention — graffiti is often viewed as a persistent, if not an intractable, problem. Few graffiti offenders are apprehended, and some change their methods and locations in response to possible apprehension and cleanups.
As with most forms of vandalism, graffiti is not routinely reported to police. Many people think that graffiti is not a police or "real crime" problem, or that the police can do little about it. Because graffiti is not routinely reported to police or other agencies, its true scope is unknown. But graffiti has become a major concern, and the mass media, including movies and websites glamorizing or promoting graffiti as an acceptable form of urban street art, have contributed to its spread.
Although graffiti is a common problem, its intensity varies substantially from place to place. While a single incident of graffiti does not seem serious, graffiti has a serious cumulative effect; its initial appearance in a location appears to attract more graffiti. Local graffiti patterns appear to emerge over time, thus graffiti takes distinctive forms, is found in different locations, and may be associated with varying motives of graffiti offenders. These varying attributes offer important clues to the control and prevention of graffiti.
For many people, graffiti's presence suggests the government's failure to protect citizens and control lawbreakers. There are huge public costs associated with graffiti: an estimated $12 billion a year is spent cleaning up graffiti in the United States. Graffiti contributes to lost revenue associated with reduced ridership on transit systems, reduced retail sales and declines in property value. In addition, graffiti generates the perception of blight and heightens fear of gang activity.
Graffiti is not an isolated problem. It is often related to other crime and disorder problems, including:
Understanding the factors that contribute to your problem will help you frame your own local analysis questions, determine good effectiveness measures, recognize key intervention points, and select appropriate responses.
There are different types of graffiti. The major types include:
In areas where graffiti is prevalent, gang and tagger graffiti are the most common types found. While other forms of graffiti may be troublesome, they typically are not as widespread. The proportion of graffiti attributable to differing motives varies widely from one jurisdiction to another.† The major types of graffiti are discussed later.
† A count in a San Diego area with a lot of graffiti showed that about 50 percent was gang graffiti; 40 percent, tagger graffiti; and 10 percent, nongroup graffiti (San Diego Police Department 2000). In nearby Chula Vista, Calif., only 19 percent of graffiti was gang-related (Chula Vista Police Department 1999). Although the counting methods likely differ, these proportions suggest how the breakdown of types of graffiti varies from one jurisdiction to another.
Graffiti typically is placed on public property, or private property adjacent to public space. It is commonly found in transportation systems — on inner and outer sides of trains, subways and buses, and in transit stations and shelters. It is also commonly found on vehicles; walls facing streets; street, freeway and traffic signs; statues and monuments; and bridges. In addition, it appears on vending machines, park benches, utility poles, utility boxes, billboards, trees, streets, sidewalks, parking garages, schools, business and residence walls, garages, fences, and sheds. In short, graffiti appears almost any place open to public view.
In some locations, graffiti tends to recur. In fact, areas where graffiti has been painted over — especially with contrasting colors — may be a magnet to be revandalized.† Some offenders are highly tenacious — conducting a psychological battle with authorities or owners for their claim over an area or specific location. Such tenacity appears to be related to an escalating defiance of authority.
† Most sources suggest that paintover colors should closely match, rather than contrast with, the base. Contrasting paint-overs are presumed to attract or challenge graffiti offenders to repaint their graffiti; the painted-over area provides a canvass to frame the new graffiti.
Graffiti locations are often characterized by the absence of anyone with direct responsibility for the area. This includes public areas, schools, vacant buildings,2 and buildings with absentee landlords. Offenders also target locations with poor lighting and little oversight by police or security personnel.
Some targets and locations appear particularly vulnerable to graffiti:
In addition, two types of surfaces attract graffiti:
While making graffiti does not offer material reward to offenders, contrary to public opinion, it does have meaning. Rather than being a senseless destruction of property, graffiti fulfills certain psychological needs, including providing excitement and action, a sense of control and an element of risk. The different types of graffiti are associated with different motives, although these drives may overlap.† Distinguishing between types of graffiti and associated motives is a critical step for developing an effective response.
† The description of types of graffiti and motives of graffiti offenders draws from broader typologies and motives associated with vandalism. See, for example, Coffield (1991) and Cohen (1973).
Historically, much conventional graffiti has represented a youthful "rite of passage" — part of a phase of experimental behavior. Such graffiti is usually spontaneous and not malicious in nature; indeed, spontaneous graffiti has often been characterized as play, adventure or exuberance. Spontaneous graffiti may reflect local traditions and appear on "fair targets" such as abandoned buildings or schools. Communities have often tolerated such graffiti.
The motives for some types of conventional graffiti may include anger and hostility toward society, and the vandalism thus fulfills some personal psychological need.3 The graffiti may arise from boredom, despair, resentment, failure, and/or frustration, in which case it may be vindictive or malicious.
A related type of graffiti is ideological. Ideological graffiti expresses hostility or a grievance — often quite explicitly. Such graffiti is usually easily identified by its content, reflecting a political, religious, ethnic, or other bias. Offenders may strategically target certain locations to further the message.
In contrast to conventional and ideological graffiti, the primary motive for gang graffiti is tactical; the graffiti serves as a public form of communication — to mark turf, convey threats or boast of achievements.4
Some tagger graffiti may involve creative expression, providing a source of great pride in the creation of complex works of art. Most taggers seek notoriety and recognition of their graffiti — they attach status to having their work seen. Thus, prolonged visibility due to the sheer volume, scale and complexity of the graffiti,† and placement of the graffiti in hard-to-reach places†† or in transit systems, enhance the vandal's satisfaction.5 Because recognition is important, the tagger tends to express the same motif — the graffiti's style and content are replicated over and over again, becoming the tagger's unique signature.
† This includes complex, artistic graffiti known as masterpieces.
†† Taggers in California used climbing equipment to tag freeway overpasses, knowing their tags would be highly visible for extended periods, until the road was shut down for paint-overs (Beatty 1990). Hardto-reach places also provide an element of danger of apprehension or physical risk, contributing to the vandal's reputation.
Participation in graffiti is often inadvertently encouraged through police contacts, media attention and public recognition of it through advertising or art displays — all can serve to enhance the offender's reputation or notoriety.6

† Copycat graffiti looks like gang graffiti, and may be the work of gang wanna-bes or youths seeking excitement.
†† Offenders commonly use numbers as code in gang graffiti. A number may represent the corresponding position in the alphabet (e.g., 13 = M, for the Mexican Mafia), or represent a penal or police radio code.
††† Stylized alphabets include bubble letters, block letters, backwards letters, and Old English script.
†††† Tagbangers, a derivative of tagging crews and gangs, are characterized by competition with other crews. Thus crossedout tags are features of their graffiti.
††††† The single-line writing of a name is usually known as a tag, while slightly more complex tags, including those with two colors or bubble letters, are known as throw-ups.
Graffiti offenders are typically young and male. In one study, most offenders were ages 15 to 23; many of the offenders were students. Offenders may typically be male, inner-city blacks and Latinos, but female, as well as white and Asian, participation is growing.7 The profile clearly does not apply in some places where the population is predominantly white. Tagging is not restricted by class lines.
In Sydney, Australia, graffiti offenders, while mostly boys, include girls; offenders are typically ages 13 to 17.8 In San Diego, all the taggers identified within a two-mile area were male, and 72 percent were 16 or younger.9 Graffiti offenders typically operate in groups, with perhaps 15 to 20 percent operating alone.10 In addition to the varying motives for differing types of graffiti, peer pressure, boredom, lack of supervision, lack of activities, low academic achievement, and youth unemployment contribute to participation in graffiti. Graffiti offenders often use spray paint, although they may also produce graffiti with large markers or by etching, the latter especially on glass surfaces.† Spray paint is widely available, easily concealed, easily and quickly used on a variety of surfaces, available in different colors with different nozzles to change line widths — these factors make spray paint suitable for a range of offenders.††
† Other tools for graffiti include shoe polish, rocks, razors, glass cutters, and glass etching fluid. Glass etching fluids include acids, such as Etch Bath and Armour Etch, developed as hobby products for decorating glass. Vandals squirt or rub the acids onto glass.
†† Vandals may adapt or modify tools and practices to cleaning methods. In New York City, when transit system personnel used paint solvents to remove graffiti, offenders adapted by spraying a surface with epoxy, writing their graffiti and then coating the surface with shellac, which proved very difficult to remove.
The making of graffiti is characterized by anonymity — hence relative safety from detection and apprehension. Most offenders work quickly, when few people are around. Graffiti predominantly occurs late on weekend nights, though there is little systematic evidence about this. In British transit studies, graffiti incidents typically occurred in off-peak or non-rush hours.11 In Bridgeport, Conn., graffiti incidents were concentrated from 5 p.m. to 4 a.m. Thursdays through Sundays.12 A San Diego study showed that routes leading away from schools were hit more frequently, suggesting a concentration in after-school hours Monday through Friday. Offenders tagged school walls daily.13
There is widespread concern that participation in graffiti may be an initial or gateway offense from which offenders may graduate to more sophisticated or harmful crimes. Graffiti is sometimes associated with truancy, and can involve drug and/or alcohol use. Graffiti offenders who operate as members of gangs or crews may also engage in fighting.
You must combine the basic facts provided above with a more specific understanding of your local problem. Analyzing the local problem helps in designing a more effective response strategy.
The following are some critical questions you should ask in analyzing your particular problem of graffiti, even if the answers are not always readily available. If you fail to answer these questions, you may select the wrong response.
† See Otto, Maly and Schismenos (2000) for more information about this technology, as used in Akron, Ohio.
†† Maps of graffiti have been used to map gang violence and gang territory. See, for example, Kennedy, Braga and Piehl (1997) [PDF].
† Photographs of offenders and their address information can also be linked to maps.
†† Police in some cities have posed as film crews, interviewing taggers about their practices.
Research shows that graffiti can be substantially reduced, and sometimes eliminated. The following are potentially useful measures of the effectiveness of responses to graffiti. To track possible displacement, such measures should be routine:
Some jurisdictions track the numbers of arrests made, gallons of paint applied or square feet covered, amount of graffiti removed, or money spent on graffiti eradication;14 these measures indicate how much effort has been put into the antigraffiti initiative, but they do not tell you if the amount or nature of graffiti has changed in any way.† You should choose measures based on the responses chosen; for example, if paint sales are limited, you should place more emphasis on tracking the type of graffiti tool used. Tools do change; for example, some offenders have begun using glass etching fluid.
† Because many anti-graffiti strategies are quite expensive, a costbenefit analysis will provide a baseline measure of benefits associated with specific costs of different strategies.
It is widely believed that graffiti is easily displaced,† but evidence of such displacement is scant. The notion that graffiti is an intractable problem that is easily displaced has been fueled by haphazard and piecemeal crime prevention measures.15 Useful measures of graffiti will assess the extent to which graffiti is reduced or moved to different locations, or reflect a change in offenders' tactics. While graffiti offenders can be persistent and adaptive, there is no reason to assume that displacement will be complete; indeed, successful responses may have a widespread effect.
† The response to graffiti in the New York subway system resulted in some reported displacement to buses, garbage trucks, walls, and other objects in the city (Butterfield 1988; Coffield 1991).
Your analysis of your local problem should give you a better understanding of the factors contributing to it. Once you have analyzed your local problem and established a baseline for measuring effectiveness, you should consider possible responses to address the problem.
The following response strategies provide a foundation of ideas for addressing your particular problem. These strategies are drawn from a variety of research studies and police reports. Several of these strategies may apply to your community's problem. It is critical that you tailor responses to local circumstances, and that you can justify each response based on reliable analysis. In most cases, an effective strategy will involve implementing several different responses. Law enforcement responses alone are seldom effective in reducing or solving the problem. Do not limit yourself to considering what police can do: give careful consideration to who else in your community shares responsibility for the problem and can help police better respond to it.
Graffiti is not solely a police problem. The police role should be one of support and assistance. Effective responses to graffiti may combine management practices, design and maintenance, and involve the general public, individual victims, criminal justice officials such as prosecutors and judges, and others. Responses to graffiti should be comprehensive and coordinated, while costs and available resources should be carefully evaluated.
Responses to graffiti must be thorough and consistent, as some offenders may be highly opportunistic, adaptive and tenacious. Responses should include ways to monitor graffiti and address changes in time, location and methods of applying it.
Rapid identification and removal of graffiti has been shown to reduce its occurrence.† This approach directly addresses the motives of many offenders by reducing the notoriety associated with graffiti's visibility. The two-step process involves routine monitoring to quickly spot graffiti, and rapid removal of the graffiti. In New York's successful approach to transit graffiti, it was initially removed within two hours of identification.†† In St. Petersburg, Fla., business owners are required to remove graffiti within 48 hours.16
† This "law of diminishing vandalism" is that persistence in cleaning up pays off. See SloanHowitt and Kelling (1990); Scott (1989); Cheetham (1994); Clarke (1978) [PDF]; and Governing (1994).
†† If graffiti cannot be removed quickly, trains are taken out of service. For train stations, graffiti is removed within 72 hours. Similar quick cleanups have occurred in Philadelphia (Scott 1989). In London, graffiti is cleaned from large stations within 24 hours.
† Police usually encourage citizens to call 911 regarding graffiti in progress; they discourage citizens from confronting offenders. Citizens can report graffiti not in progress to hotlines.
Some jurisdictions pay graffiti reporters' cell phone charges. In London, people can use free telephones in transit stations to report offenses. In other jurisdictions, transit riders are encouraged to report graffiti and offenders. Numerous jurisdictions offer a cash reward of $200 to $1,000 if a tip leads to a conviction.
In some jurisdictions, graffiti reports may be suppressed due to concerns about retaliation by gang members or taggers. Widespread public participation in both open and anonymous reporting usually addresses these concerns, but police should be aware of this potential problem.
The experiences of the New York City Transit System illustrate varying approaches to graffiti. Graffiti began to appear on subway trains in the 1960s; by 1970, it was a huge problem. The public was fearful, and ridership on trains declined.
The motive for the graffiti was "getting up" and getting noticed; there were no indications the graffiti was gang-related. Instead, the graffitists or taggers sought to build their reputation through the sheer quantity of their graffiti. As competition among them increased, they distinguished themselves through writing style, embellishment, graffiti size, and location — either in unusual spots or in previously unmarked spots. One prolific vandal produced 10,000 graffiti markings.
Despite the severity of its ongoing fiscal crisis, New York City adopted a variety of anti-graffiti strategies in the 1970s: punishing offenders by making them clean up trains marked with graffiti; using fencing with razor wires to protect the vast train yards; and developing materials to ease graffiti removal, materials that were later found to be environmentally hazardous. The methods all failed to substantially reduce the amount of graffiti.
In 1984, the city adopted a system to monitor trains and clean those marked with graffiti within two hours; otherwise, they took the cars out of service. They also began to store clean trains in highly secure yards that featured 24-hour-a-day work crews, enhanced lighting, routine fence maintenance, and undercover police. The initiative focused on the most problematic times, locations and train lines; initially, all trains were monitored, but random checks were later successfully used to maintain clean trains. In addition, repeat offenders were targeted for parental contact and enhanced penalties.
In contrast to the earlier initiatives, this anti-graffiti effort began with a handful of trains (those detected with graffiti) and built up to cover the entire system. Importantly, rather than focusing on using the criminal justice system, this approach addressed the offenders' underlying motives. Immediately removing graffiti-marked trains from service severely limited the vandals' exposure.
† The type of surface graffiti is placed on is a major factor because graffiti-removal products may damage some surfaces. The type of marking agent is also a factor: some paints are reversible. There is a wide range of graffiti removal products available, including chemical sprays, aerosols, gels, and poultices. Cleaners are either alkaline or acidic; the latter can damage masonry, and neutralizing techniques must be incorporated when using either. Physical removal methods include low- and high-pressure water cleaning, often with detergents, and sandblasting. Physical removal is more expensive, and is typically used for large areas where other methods have failed.There are four major types of removal or cover-ups:
The source of labor for removing graffiti may vary. Cleanup squads may consist of volunteers, employees or adjudicated offenders. Graffiti removal may be coercive. A large number of jurisdictions hold the property owner responsible for graffiti removal. Sanctioning victims requires that they clean graffiti up quickly or get fined.17 Citizens may get paint or physical assistance from volunteers, if needed. Cities can use nuisance ordinances, zoning codes or graffiti ordinances to force owners to clean up quickly, which may be necessary for absentee owners. Alternatively, some cities clean up graffiti and then bill the owner. Some cities do the first cleanup for free; the owner then has responsibility for subsequent cleanups.
Numerous jurisdictions use graffiti removal as a court-ordered sanction for offenders and other misdemeanants. In some jurisdictions, such sanctions require victim restitution, reflecting a restorative justice approach.
Because graffiti offenders usually operate in darkness, where there is little chance of being seen, few are apprehended. Increasing the likelihood of their being detected increases the risk of apprehension.
† Some of these products may produce toxic fumes in case of fire.
†† These coatings must be reapplied; the surface dissolves when graffiti is cleaned off.
††† These surfaces are harder to mark, but are difficult to clean.
† These washable walls are used in larger London train stations.
†† The alternative, polycarbonate surfaces become hazy.
Some materials cannot be effectively protected from graffiti. Graffiti-prone surfaces can be replaced with standard-sized, inexpensive materials. These include transparent, replaceable glass or polycarbonate panels in bus shelters, and replaceable polycarbonate covering signs.
††† Some of these measures impose social costs by making areas look like war zones. Access controls with forbidding appearances may be better left to isolated areas.
In some cases, signs have been moved out of reach of vandals, while bus stops and other frequently vandalized targets have been relocated. Environmental design to limit access to graffiti surfaces can best be incorporated into planning and construction, but may also be adapted to existing structures. An example of effective environmental design is the recessed walls of the Washington, D.C., metro system; subway walls are physically separated from the public.
Police or security patrols, guards and dogs may supplement access control. Access to residential or commercial properties may be restricted to those with resident or employee identification cards, while visitor access may be controlled through entry phones.
Much like environmental design, situational design reduces the opportunity for graffiti. The absence of toilets, seating, fast food, and lockers in transit stations effectively discourages potential offenders from loitering. In Hong Kong, a limited life to transit tickets encourages people to quickly move through stations before their tickets expire, thus discouraging loitering. In Washington, D.C., the subway system generally closes at midnight on weekdays and somewhat later on weekends, thus limiting opportunities for vandalism. Since graffiti often takes place late at night, limiting hours reduces opportunities for vandalism at times when there are typically few other riders or employees to deter the offender or witness the offense.
Some graffiti offenders are prolific; a small group typically accounts for a large portion of all offenses. Efforts that focus on chronic offenders show promise. Chronic offenders can be identified through graffiti investigations. Since offenders tend to replicate their graffiti, it has unique characteristics, like a signature, and different incidents or tags can be linked to a single offender. Some taggers practice their tags in notebooks or take photographs to document their efforts; these may be used as evidence to link offenders to graffiti incidents.
Some police conduct surveillance of known offenders and/or high-risk hot spots, collaborate with schools to detect offenders, and monitor chronic offenders, particularly those on probation. Police may use extensive intelligence databases to record information about graffiti content, locations and offenders. Such databases may include photographs or video of graffiti, mug shots of offenders, and maps of graffiti locations.
Numerous responses have been incorporated into efforts to control graffiti. Most have not been carefully evaluated, and are thus of unknown effectiveness. Any response can be effective if it increases the difficulties of offending and reduces the rewards for it. Many responses, however, are quite difficult to enforce.
Controlling graffiti tools. A number of jurisdictions have tried to control the tools used for graffiti. Boston and other cities have banned the sale of large, wide-tipped markers. In addition, bans on spray paint sales to minors have been widely used in recent years.† Some jurisdictions require stores to be licensed for and to limit spray paint sales, and require buyers to furnish their name and address. In some jurisdictions, juvenile possession of spray paint or large, indelible markers without supervision is a misdemeanor.
† Chicago has had such a ban since 1980.
Efforts have been made to reduce shoplifting of spray paint by placing stock away from exits and removing it from open displays. Instead, stock is often stored behind counters, in storerooms or in locked display cases. Some jurisdictions require stores to place markers in full view of clerks. Industry efforts have also been made to regulate graffiti tools. Spray valves can be modified, and restricted-use caps limited, so that offenders cannot change caps.†† Some jurisdictions encourage proper disposal of contractor painting materials so that graffiti offenders cannot access them.
†† Graffiti offenders prefer interchangeable caps, allowing them to combine thick and thin lines. Wide caps or other caps from oven cleaners or spray starch are especially desirable.
While there have been no evaluations of efforts that limit graffiti tools, enforcing local ordinances that do so can be difficult. Although restrictions on possession of supplies may provide an additional enforcement tool, graffiti offenders are rarely apprehended. In many tagging groups, one person carries the graffiti supplies, making it more difficult to obtain the evidence that may be necessary for a conviction.
††† Nugent (1998) describes a graffiti wall in Washington, D.C.'s Lafayette Park; Coffield (1991) notes the painting of a Southampton, England, garage.
Similarly, some jurisdictions have commissioned murals to cover up graffiti or improve the community's appearance. These murals are often located where graffiti has posed a problem. Graffiti offenders appear to respect the artwork on such murals, but the surfaces can be protected with antigraffiti coating. Murals and walls showcase artists' work and may reduce incentives to vandalize. Similar initiatives to divert offenders have included art classes or programs for reformed offenders, some of which involve a contract or pledge not to produce further graffiti. These efforts may be effective in reducing the amount of graffiti in specific locations.
Some anti-graffiti programs involve educating youth about the harms and costs of graffiti. The youth-targeted message that graffiti is uncool is conveyed through subway and bus posters, and television and radio commercials. Sports figures may endorse the message to add potency to it.
In some cases, former graffiti offenders create murals with anti-graffiti messages, give public talks, counsel other offenders, and organize graffiti cleanups.
Many jurisdictions use graffiti cleanup for community service to avoid adjudication, as a condition of probation, or as part of a disposition or sentence. Some communities have restorative justice initiatives in which face-to-face victim-offender reconciliation occurs, a contract is signed, and offenders pay restitution.
In some jurisdictions, students are suspended or expelled from school for graffiti offenses. A large number of jurisdictions have involved courts in treating graffiti incidents seriously, systematically imposing fines, community service and even jail time on chronic offenders.
New anti-graffiti technologies include the following:
Since developing or purchasing new technologies may be quite costly for most jurisdictions, such responses should be carefully evaluated first. New technologies to respond to graffiti will likely continue to become available.
† In some limited studies of bathroom graffiti (Mueller et al. 2000; Watson 1996), posting signs warning of sanctions, containing positive messages appealing to altruism, or conveying neutral messages — "Please do not write on these walls" — resulted in a decline in graffiti.
The table below summarizes the responses to graffiti, the mechanism by which they are intended to work, the conditions under which they ought to work best, and some factors you should consider before implementing a particular response. It is critical that you tailor responses to local circumstances, and that you can justify each response based on reliable analysis. In most cases, an effective strategy will involve implementing several different responses. Law enforcement responses alone are seldom effective in reducing or solving the problem.
