Place and Crime - Environmental Criminology

Place and crime is the organizing concept of environmental criminology, capturing the finding that criminal events cluster overwhelmingly at a small number of specific locations rather than distributing evenly across neighborhoods, cities, or even the individuals who commit and suffer them. Within the Environmental Criminology silo, this article introduces place as a distinct unit of criminological analysis, tracing how criminologists came to treat specific addresses, intersections, and street segments as legitimate objects of study in their own right rather than as mere backdrops to offender behavior. The place-based perspective represents a fundamental reorientation of criminological inquiry away from questions of who commits crime and why toward questions of where crime occurs and what it is about those specific locations that makes them so persistently attractive to offending, a reorientation with far-reaching implications for both criminological theory and criminal justice practice.

Introduction

For much of the twentieth century, mainstream criminology organized itself almost entirely around the offender, asking what biological, psychological, or sociological factors distinguish people who commit crime from people who do not, a framing that treated the physical location of a criminal event as largely incidental to the causal story. The place-based perspective that emerged from environmental criminology beginning in the 1970s and 1980s inverted this framing, asking instead why crime concentrates so heavily at certain addresses and street segments while leaving the overwhelming majority of locations, even within high-crime neighborhoods, essentially crime-free across long periods of observation.

This article traces the emergence of place as a criminological unit of analysis, examines the empirical evidence documenting crime’s concentration at specific locations, explores the theoretical mechanisms environmental criminologists have proposed to explain that concentration, and considers the methodological and policy implications of taking place seriously as a criminological variable in its own right, implications explored in greater depth across the companion articles that make up this Environmental Criminology silo.

The Emergence of Place as a Criminological Unit of Analysis

From Offender-Centered to Place-Centered Criminology

Criminology’s traditional offender-centered orientation, rooted in the Positivist School’s search for individual and social causes of criminality, dominated the discipline through the Chicago School’s ecological research and into the sociological criminology of Sutherland, Merton, and their successors, all of which asked fundamentally why particular individuals or groups become involved in crime (Brantingham & Brantingham, 1981). Even the Chicago School’s own ecological work, which mapped delinquency rates across urban zones, treated the neighborhood rather than the specific address or street segment as its unit of analysis, aggregating crime counts across areas large enough to contain thousands of residents and hundreds of distinct physical locations, a level of aggregation that obscured the substantial variation in crime risk existing within any given neighborhood.

Patricia and Paul Brantingham’s foundational work in environmental criminology, beginning in the late 1970s, argued that this neighborhood-level aggregation concealed more than it revealed, since even the highest-crime neighborhoods contain a great many addresses that experience no criminal victimization across years of observation alongside a small number of addresses that generate disproportionate shares of neighborhood crime (Brantingham & Brantingham, 1981). This observation motivated a shift toward finer-grained units of analysis, first to census blocks and eventually to individual street segments and addresses, a methodological progression that revealed patterns of crime concentration invisible at the neighborhood level of analysis.

The Brantinghams’ subsequent development of crime pattern theory extended this place-centered orientation by proposing that individuals develop cognitive maps of their routine activity spaces, the areas encompassing their homes, workplaces, and the paths connecting them, and that criminal opportunities encountered within these familiar activity spaces are disproportionately likely to be acted upon relative to opportunities encountered in unfamiliar territory (Brantingham & Brantingham, 1993). This activity-space framing supplied a further theoretical rationale for expecting crime to concentrate at specific, identifiable locations rather than distributing randomly across an urban area, since the locations offenders are most likely to encounter and exploit criminal opportunity are precisely those falling within their own routine, non-criminal daily movements.

Environmental Criminology’s Founding Contributions

C. Ray Jeffery’s 1971 book Crime Prevention Through Environmental Design and Oscar Newman’s 1972 study Defensible Space independently arrived at a compatible conclusion from architectural and urban-planning rather than sociological starting points, arguing that the physical design of buildings and neighborhoods directly shapes opportunities for crime and that modifying that design could meaningfully reduce criminal victimization independent of any change in the surrounding population’s underlying criminal propensity (Newman, 1972). Newman’s research on public housing developments found that buildings sharing similar resident populations and surrounding neighborhood conditions nonetheless displayed sharply different crime rates depending on specific design features, including the visibility of common areas and the clarity of territorial boundaries between public and private space, providing early empirical support for the claim that place itself, independent of who occupies it, shapes criminal opportunity.

These architectural and planning-oriented contributions converged with the Brantinghams’ more explicitly criminological environmental criminology and with Lawrence Cohen and Marcus Felson’s routine activity approach to form a broader intellectual movement treating place as a criminologically consequential variable, a convergence that Ronald Clarke’s subsequent situational crime prevention framework, examined in the companion article on CPTED in America elsewhere in this silo, would later systematize into a comprehensive framework for place-based crime reduction (Clarke, 1980).

Jane Jacobs’s earlier 1961 study The Death and Life of Great American Cities, though written as urban planning criticism rather than criminology, anticipated several of these place-based insights by nearly a decade, arguing that vibrant, well-used public spaces characterized by what she termed natural surveillance, the informal watchfulness generated by shopkeepers, residents, and passersby going about their ordinary business, discouraged crime and disorder more effectively than either architectural fortification or increased formal policing (Jacobs, 1961). Jacobs’s emphasis on mixed land use, pedestrian activity, and the informal social control generated by an active, well-populated streetscape directly anticipated Newman’s later, more systematically criminological articulation of defensible space and would eventually inform the natural surveillance principle examined in dedicated depth in the companion article on natural surveillance and crime prevention elsewhere in this silo.

The Empirical Concentration of Crime at Place

Early Documentation of Crime Hot Spots

Lawrence Sherman, Patrick Gartin, and Michael Buerger’s landmark 1989 study of calls for police service in Minneapolis provided some of the earliest and most influential quantitative documentation of crime’s concentration at specific addresses, finding that just over three percent of all addresses and intersections in the city generated over fifty percent of all calls for police service across the year studied, a degree of concentration considerably more extreme than criminologists working at the neighborhood level had previously appreciated (Sherman, Gartin, & Buerger, 1989). This finding, replicated across numerous subsequent studies employing varied cities, time periods, and crime types, established what has become one of criminology’s most consistently replicated empirical regularities, examined in greater analytical depth in the companion article on Crime Concentration elsewhere in this silo.

David Weisburd’s subsequent research extended this documentation considerably, proposing what he termed the law of crime concentration at place, the empirical finding that a remarkably consistent proportion of a city’s crime, typically somewhere between four and six percent of street segments, accounts for approximately fifty percent of total crime across cities of vastly different sizes, structures, and historical periods, a consistency Weisburd argued rivaled the strength of well-established regularities in the natural sciences (Weisburd, 2015). Jerry Ratcliffe’s subsequent methodological work on hot spot identification cautioned that this striking degree of concentration also depends considerably on how researchers define a hot spot, whether through simple visual inspection of point-pattern maps, kernel density estimation, or more formal statistical clustering techniques, and that different identification methods can generate meaningfully different conclusions about the precise boundaries and stability of any given hot spot (Ratcliffe, 2004).

Stability of Crime Concentration Over Time

Beyond documenting crime’s concentration at a single point in time, subsequent research has found that this concentration remains remarkably stable across years and even decades, with the specific addresses and street segments generating disproportionate crime in one year typically continuing to do so in subsequent years, a stability finding with significant implications for both theory and policy (Weisburd, 2015). Elizabeth Groff, David Weisburd, and Sue-Ming Yang’s longitudinal analysis of crime trajectories across Seattle street segments found that while city-wide crime rates fluctuated considerably across the sixteen-year period they examined, the relative ranking of individual street segments by crime volume remained substantially stable, with high-crime segments generally remaining high-crime and low-crime segments generally remaining low-crime even as aggregate city-wide crime rose and fell (Groff, Weisburd, & Yang, 2010).

This temporal stability finding proved theoretically significant because it suggested that crime concentration reflects durable features of specific locations rather than transient conditions or randomly shifting offender behavior, reinforcing the case for treating place itself, rather than merely the people who happen to occupy it at any given moment, as a stable and criminologically consequential unit of analysis warranting sustained empirical attention in its own right. James Wilson and George Kelling’s influential, if separately debated, account of neighborhood disorder similarly emphasized the durability of place-level conditions, arguing that visible signs of physical and social disorder at specific locations could persist and even compound over time absent active intervention, a durability argument that, whatever its independent merits as a theory of disorder specifically, reinforced the broader environmental criminology premise that place-level conditions exhibit meaningful stability warranting sustained rather than one-time analytical and policy attention (Wilson & Kelling, 1982).

Theoretical Mechanisms Explaining Crime’s Concentration at Place

Routine Activity and the Convergence of Necessary Elements

Cohen and Felson’s routine activity approach supplies one of the most influential theoretical accounts of why crime concentrates at specific places, proposing that a criminal event requires the convergence in space and time of a motivated offender, a suitable target, and the absence of a capable guardian, a convergence that some locations, by virtue of their specific physical and social characteristics, host far more frequently than others (Cohen & Felson, 1979). This convergence-based account directly explains crime concentration at place, since locations that reliably bring together offenders, targets, and inadequate guardianship, such as certain bars, transit stops, or poorly monitored parking facilities, should predictably generate disproportionate criminal opportunity relative to locations where these elements rarely align. Derek Cornish and Ronald Clarke’s complementary rational choice perspective supplied a decision-theoretic account of why offenders exploit exactly these convergence-rich locations, proposing that offenders engage in a bounded, situationally constrained assessment of the effort, risk, and reward a given criminal opportunity presents, an assessment that certain physical and social features of place can systematically shift toward or away from favoring offending (Cornish & Clarke, 1986).

Marcus Felson’s later elaboration of this framework introduced the related concepts of crime generators and crime attractors, examined in dedicated depth in the companion article on Crime Generators and Crime Attractors elsewhere in this silo, distinguishing locations that produce crime opportunities simply by drawing large numbers of people together, regardless of their criminal intent, from locations that specifically draw motivated offenders because of their known criminal opportunities (Felson, 1995). Felson’s broader treatment of crime and everyday life extended this convergence-based reasoning to argue that mundane changes in routine daily activity, including shifts in work schedules, shopping patterns, and leisure activity, could substantially alter aggregate crime rates by systematically reshaping when and where potential offenders, targets, and guardians converge, without requiring any change whatsoever in the underlying population’s criminal motivation (Felson, 1998).

Guardianship, Territoriality, and Place Management

Beyond the convergence of offenders and targets, environmental criminologists have emphasized the role of place management and guardianship in explaining why some locations resist crime despite otherwise favorable conditions for offending, with John Eck and David Weisburd’s influential framework identifying place managers, including property owners, employees, and residents with a stake in a location’s orderly functioning, as a distinct category of control operating alongside more general guardianship (Eck & Weisburd, 1995). Effective place management, involving active monitoring, prompt maintenance, and clear communication of behavioral expectations, appears to substantially reduce a location’s crime risk independent of its surrounding neighborhood context, helping explain why crime concentration persists even within demographically similar areas. Robert Sampson and W. Byron Groves’s neighborhood-level research on collective efficacy, while conducted primarily at a broader spatial scale than the individual place-management research Eck and Weisburd’s framework addresses, found a structurally compatible pattern, since neighborhoods characterized by stronger informal social control and mutual trust among residents displayed substantially lower crime rates independent of structural disadvantage, reinforcing at a broader scale the same guardianship logic operating at the level of individual places (Sampson & Groves, 1989).

Ralph Taylor’s research on territorial functioning further identified how residents’ and users’ sense of ownership and responsibility for a specific physical space shapes their willingness to intervene when disorder or crime occurs there, with strong territorial identification associated with more active informal guardianship and correspondingly reduced crime risk, a psychological and social mechanism operating alongside the more structural place-management factors Eck and Weisburd identified (Taylor, 1988). Danielle Reynald’s later empirical research on guardianship in action extended this territorial framework by directly observing residents’ actual monitoring and intervention behavior rather than relying solely on survey-based attitudinal measures, finding that residents’ willingness to intervene varied considerably depending on both their perceived territorial responsibility for the specific location and the perceived seriousness of the observed behavior, a refinement that has informed more precise measurement of guardianship as a place-level protective factor (Reynald, 2011).

Methodological Implications of the Place-Based Perspective

Units of Analysis and the Modifiable Areal Unit Problem

Taking place seriously as a criminological variable has required environmental criminologists to grapple directly with what geographers term the modifiable areal unit problem, the methodological challenge that statistical relationships observed at one level of spatial aggregation, such as the neighborhood, may not hold, or may even reverse, when the same data are reaggregated to a different spatial unit, such as the street segment or individual address (Weisburd, 2015). This methodological challenge has motivated environmental criminologists to argue explicitly for street segments and individual addresses as the theoretically appropriate unit of analysis for studying crime concentration, rather than treating unit selection as a matter of convenience dictated by whatever data happen to be readily available.

This unit-of-analysis debate carries direct implications for the geographic information systems and crime-mapping methods examined in the companion article on GIS and Crime Mapping elsewhere in this silo, since the choice of spatial unit fundamentally shapes what patterns a given mapping or analytical approach can detect, with overly aggregated units systematically obscuring the fine-grained concentration patterns environmental criminology has identified as its central empirical phenomenon. Wesley Skogan’s earlier research on neighborhood disorder, though conducted primarily at the neighborhood rather than street-segment level, nonetheless anticipated the value of finer spatial resolution by documenting that physical and social disorder, including vandalism, litter, and public drinking, varied considerably even within neighborhoods researchers had previously treated as relatively homogeneous units, a within-neighborhood variability that later street-segment research would document with considerably greater spatial precision (Skogan, 1990).

Micro-Place Research Designs

The place-based perspective has also motivated distinctive research designs specifically suited to studying crime at fine spatial resolution, including systematic social observation protocols in which trained observers directly assess physical and social conditions at specific addresses, and longitudinal panel designs tracking the same street segments across extended time periods to distinguish stable, place-based crime risk from transient fluctuation, examined further in the companion article on Micro-Places and Crime elsewhere in this silo (Groff, Weisburd, & Yang, 2010). These methodological innovations have allowed researchers to move beyond simply documenting that crime concentrates at place toward identifying the specific physical, social, and management characteristics that distinguish high-crime from low-crime locations sharing otherwise similar neighborhood contexts.

This methodological progression, from neighborhood-level ecological correlation through address-level hot spot mapping to systematic observation of place-level physical and social characteristics, illustrates how the place-based perspective has matured from an initially descriptive empirical observation into a genuinely explanatory research program capable of generating testable predictions about which specific interventions should reduce crime at which specific types of locations.

Policy and Practice Implications of Place-Based Criminology

Hot Spots Policing and Targeted Resource Allocation

The empirical concentration of crime at a small number of identifiable locations carries an immediately apparent policy implication: police and other crime-prevention resources can be allocated far more efficiently by targeting the specific hot spots generating disproportionate crime rather than distributing patrol and prevention resources evenly across an entire jurisdiction, an implication examined in dedicated depth in the companion article on Hot Spots Policing elsewhere in this silo (Sherman, Gartin, & Buerger, 1989). Anthony Braga’s meta-analytic synthesis of hot spots policing evaluations found consistent evidence that focused police attention on identified crime hot spots produces meaningful crime reductions at those specific locations, with the strength of this evidence contributing substantially to hot spots policing’s status as one of contemporary policing’s most empirically supported strategic innovations (Braga, 2001). Braga’s subsequent updated meta-analysis, incorporating a considerably larger and more methodologically rigorous body of evaluation studies accumulated over the following decade, confirmed and strengthened this original finding, reporting consistent crime-reduction effects across studies employing randomized and quasi-experimental designs alike and finding little evidence that these effects were driven primarily by weaker, non-randomized studies (Braga, Papachristos, & Hureau, 2014).

This resource-allocation implication extends beyond policing specifically to inform broader place-based crime prevention strategy, examined in the companion article on Place-Based Crime Prevention elsewhere in this silo, since municipal code enforcement, business licensing, and physical environment modification can similarly be targeted toward identified high-crime locations rather than applied uniformly across a jurisdiction. Ronald Clarke’s subsequently expanded situational crime prevention framework, cataloguing twenty-five distinct techniques organized around increasing effort, increasing risk, reducing reward, reducing provocation, and removing excuses, supplied practitioners with a systematic menu of place-specific interventions extending well beyond policing alone, a framework examined in fuller detail in the companion article on CPTED in America elsewhere in this silo (Clarke, 1997).

Displacement Concerns and Diffusion of Benefits

Place-based crime prevention strategies have faced persistent skepticism grounded in displacement theory, the concern that concentrating prevention resources at specific hot spots simply displaces criminal activity to nearby, less-monitored locations rather than genuinely reducing overall crime, a concern examined in detail in the companion article on Crime Displacement and Diffusion of Benefits elsewhere in this silo (Guerette & Bowers, 2009). Rob Guerette and Kate Bowers’s systematic review of displacement research found that displacement, when it occurs at all, typically proves considerably smaller in magnitude than the crime reduction achieved at the targeted location, and that many place-based interventions instead generate a diffusion of benefits, in which crime reduction spreads to nearby untreated locations rather than crime itself displacing to them. Their review, synthesizing 102 evaluations of situational crime prevention interventions, found that diffusion of benefits was reported more frequently than displacement across the studies examined, a finding that directly challenged the assumption, common among earlier critics of place-based prevention, that displacement should be expected as a near-automatic consequence of any successful place-targeted intervention (Guerette & Bowers, 2009).

This displacement and diffusion research has proven important for defending place-based crime prevention against a natural theoretical objection, since a purely offender-centered account of crime might predict that motivated offenders, if prevented from offending at one location, would simply relocate their criminal activity elsewhere, while the empirical evidence instead suggests that place-specific opportunity structures exert genuine causal influence on whether and where criminal behavior actually occurs, a finding consistent with the broader theoretical mechanisms this article has examined throughout.

Cross-National Replication and the Generality of Place-Based Findings

Testing Crime Concentration Beyond the United States

The empirical concentration of crime at a small number of specific locations, first documented systematically in American cities including Minneapolis and Seattle, has since been replicated across a wide range of national and cultural contexts, including cities in the United Kingdom, Australia, Israel, and continental Europe, suggesting that the underlying mechanisms producing crime concentration operate independent of any specific national policing system, legal tradition, or urban form (Weisburd, 2015). This cross-national replication matters considerably for environmental criminology’s theoretical claims, since a finding confined to American cities alone might plausibly reflect some peculiarity of American urban development, gun availability, or policing practice rather than a genuine, cross-culturally consistent criminological regularity.

David Weisburd’s comparative synthesis of this cross-national literature found that the specific proportion of street segments accounting for approximately half of a city’s crime varied only modestly across the national contexts examined, typically falling within the four-to-six percent range first documented in American research, a degree of cross-national consistency that has strengthened the case for treating crime concentration as reflecting general features of how criminal opportunity distributes across urban space rather than as an artifact specific to any single country’s particular social or institutional conditions. Elizabeth Groff’s own comparative work extended this cross-national documentation to smaller and mid-sized cities beyond the large metropolitan areas that supplied much of the earliest concentration research, finding that the underlying concentration pattern held even in considerably smaller urban contexts with different street network structures and population densities, further reinforcing the generality of the place-based perspective this article develops (Groff, Weisburd, & Yang, 2010).

Extending the Place-Based Perspective to New Crime Types

While early place-based research concentrated heavily on predatory street crime, including robbery and assault, subsequent research has extended the place-based perspective to a considerably broader range of offense categories, including drug distribution, prostitution, and even certain forms of white-collar and cyber-enabled offending, generally finding that concentration patterns comparable to those documented for conventional street crime hold across this broader range of offense types as well (Eck & Weisburd, 1995). This extension has reinforced environmental criminology’s claim to theoretical generality, suggesting that the convergence-based mechanisms routine activity theory specifies operate across a considerably wider range of criminal behavior than the conventional predatory street crime that supplied much of the field’s original evidentiary base.

This broadening extension of place-based research carries direct relevance for the offense-specific applications examined throughout the remainder of this encyclopedia’s treatment of environmental criminology, including its application to drug markets, retail crime, and school safety, each of which draws on the same foundational insight that criminal opportunity concentrates predictably at identifiable locations whose specific physical and social characteristics can be documented, analyzed, and, where appropriate, modified to reduce criminal opportunity.

Conclusion

Place and crime together constitute environmental criminology’s foundational reorientation of criminological inquiry, redirecting sustained empirical and theoretical attention toward the specific physical locations where crime concentrates rather than treating location as an incidental backdrop to offender-centered explanation. Sherman, Gartin, and Buerger’s landmark documentation of crime concentration in Minneapolis, extended through Weisburd’s law of crime concentration and Groff, Weisburd, and Yang’s demonstration of its temporal stability, established one of criminology’s most consistently replicated empirical regularities, while routine activity theory and place-management frameworks have supplied compelling theoretical accounts of the underlying mechanisms producing that concentration.

This place-based perspective has generated methodological innovations in spatial unit selection and micro-place research design while informing consequential policy applications, including hot spots policing and broader place-based crime prevention, whose empirical support has been strengthened rather than undermined by careful research into displacement and diffusion effects. The place-based perspective’s continued influence across the many specific applications examined throughout this encyclopedia’s broader treatment of environmental criminology confirms its status as one of contemporary criminology’s most theoretically generative and practically consequential reorientations.
