The Relationship Between Crime and Stop,Question, and Frisk Rates in New York City Neighborhoods

The current study builds on prior research in an analysis of the relationship between monthly violent and property crime rates in New York City census tracks and the New York City Police Department’s highly contentious stop, question, and frisk (SQF) policy. We find that higher doses of SQF are associated with small crime reductions generally and specific crime reductions for stops of blacks, Hispanics, and whites. But the way the policy was implemented precludes strong causal conclusions. Now that a federal court has intervened and SQF is undergoing change, the court monitor, New York Police Department, and city officials should partner with researchers in experimental evaluations to determine the optimal mix and dosage of enforcement strategies that safeguard the rights and liberties of citizens while enhancing public safety.     

THE IMPACT OF ORDER‐MAINTENANCE POLICING ON NEW YORK CITY HOMICIDE AND ROBBERY RATES: 1988‐2001*

Local officials and national observers have attributed the New York City drop in violent crime during the 1990s to the aggressive enforcement of public order, but relevant research is limited and yields contrasting conclusions regarding the effects of order‐maintenance policing (OMP) on violent crime trends in New York City. The current study investigates the effects of order‐maintenance arrests on precinct‐level robbery and homicide trends in New York City with more reliable crime and arrest data, longer time series, and more extensive controls for other influences than used in prior research. We find statistically significant but small crime‐reduction effects of OMP and conclude that the impact of aggressive order enforcement on the reduction in homicide and robbery rates in New York City during the 1990s was modest at best.     

On the Limits of Social Control: Structural Deterrence and the Policing of “Suppressible” Crimes

The present study examined the relationships between patterns of police arrests and subsequent variations in robbery, burglary, and aggravated assault in New York City police precincts from 1989 to 1998. Grounded in the structural deterrence theoretical perspective, and using a two‐stage fixed‐effects statistical framework, the study found that while controlling for indicators of social disorganization, increases in arrest vigor (i.e., arrests per officer for violent crimes in each precinct and raw arrest counts) predicted decreases in robbery and burglary, but that the relationships were non‐linear: as arrest vigor increased, robbery and burglary crime decreased; when arrest thresholds were reached, however, both robbery and burglary crime rates became positively associated with arrest aggressiveness. Conversely, variations in aggressive arrest patterns had no significant effect on aggravated assault, supporting the suppressible crimes arguments that primarily economically motivated crimes, and those that tend to occur in public settings, are most likely deterred by aggressive police practices.     

A tale of three cities: Crime and displacement after Hurricane Katrina

When Hurricane Katrina struck New Orleans in August 2005, it greatly disrupted both the physical and social structures of that community. One consequence of the hurricane was the displacement of large numbers of New Orleans residents to other cities, including Houston, San Antonio, and Phoenix. There has been media speculation that such a grand-scale population displacement led to increased crime in communities that were recipient of large numbers of displaced New Orleans residents. This study was a case study of three cities with somewhat different experiences with Katrina's diaspora. Time series analysis was used to examine the pre- and post-Katrina trends in six Part I offenses (murder, robbery, aggravated assault, rape, burglary, and auto theft) to assess any impact of such large-scale population shifts on crime in host communities. Contrary to much popular speculation, only modest effects were found on crime. Social disorganization theory was used to frame both the analysis and the interpretation of these results.     

INFORMAL SURVEILLANCE AND STREET CRIME: A COMPLEX RELATIONSHIP*

The systemic crime model predicts that informal surveillance of space reduces street crime. Conversely, community decline theory posits that street crime reduces informal surveillance by increasing residents' perception of risk and fear. Moreover, functions of crime theory suggests that some types of crime may increase surveillance. Using data for 100 urban neighborhoods, the analysis examines these predictions and disentangles reciprocal effects. Baseline recursive equations indicate that informal surveillance is inversely associated with robbery/stranger assault, and that robbery/stranger assault is inversely associated with informal surveillance. In contrast, burglary rates are not affected by informal surveillance, but burglary has a positive effect on surveillance when robbery/stranger assault is controlled. Simultaneous equations indicate that robbery/stranger assault has a moderately strong inverse effect on informal surveillance, and that it is mediated by residents' perceptions of risk. When risk perception is controlled, informal surveillance has an inverse effect on robbery/stranger assault. The latter analysis also indicates that burglary increases surveillance, suggesting that some types of crime serve positive functions. The results, therefore, lend support to systemic, community decline, and functions of crime theory, and they suggest that the relationship between informal surveillance and crime is complex. Implications for community crime research are discussed.     

Could Innovations in Policing have Contributed to the New York City Crime Drop even in a Period of Declining Police Strength?: The Case of Stop,Question and Frisk as a Hot Spots Policing Strategy

Available data make it impossible to reach strong conclusions about the role of policing in the New York crime decline. Instead, we examine whether innovations implemented in New York fit with what is known about effective policing strategies. Our main analysis focuses on how the New York City Police Department (NYPD) could have continued to contribute to the crime drop over the last decade when the number of police declined significantly. We examine geographic data on crime and stop, question and frisks (SQFs) to show that SQFs are concentrated at crime hot spots. We also show that the NYPD increased these specific hot spots policing strategies despite declining numbers. In our discussion, we speculate on whether this “doing more with less” could be an explanation for the continued crime drop in New York, noting the limitations of drawing conclusions from existing data. We also raise concerns about possible backfire effects of SQF hot spots approaches.     

Using Space–Time Analysis to Evaluate Criminal Justice Programs: An Application to Stop-Question-Frisk Practices

Objectives

Effects of place-based criminal justice interventions extend across both space and time, yet methodological approaches for evaluating these programs often do not accommodate the spatiotemporal dimension of the data. This paper presents an example of a bivariate spatiotemporal Ripley’s K-function, which is increasingly employed in the field of epidemiology to analyze spatiotemporal event data. Advantages of this technique over the adapted Knox test are discussed.

Methods

The study relies on x–y coordinates of the exact locations of stop-question-frisk (SQF) and crime incident events in New York City to assess the deterrent effect of SQFs on crime across space at a daily level.

Results

The findings suggest that SQFs produce a modest reduction in crime, which extends over a three-day period. Diffusion of benefits is observed within 300 feet from the location of the SQF, but these effects decay as distance from the SQF increases.

Conclusions

A bivariate spatiotemporal Ripley’s K-function is a promising approach to evaluating place-based crime prevention interventions, and may serve as a useful tool to guide program development and implementation in criminology.

     

THE IMPACT OF ECONOMIC CONDITIONS ON ROBBERY AND PROPERTY CRIME: THE ROLE OF CONSUMER SENTIMENT*

Despite its long history in criminology, research on the relationship between macroeconomic conditions and rates of common crime remains limited. That is in part because many analysts doubt that any systematic relationship exists and in part because of disagreement with regard to the validity of the indicators typically used to measure economic conditions. We argue in this article that good theoretical reasons exist to expect macroeconomic effects on crime rates, but many theories imply that collective perceptions of economic hardship should have effects on crime that are independent of those of more “objective” economic indicators. To evaluate this argument, we examine the relationships between the Index of Consumer Sentiment and regional robbery, burglary, larceny, and motor vehicle theft rates in the United States between 1970 and 2003, which was a period of large swings in both consumer sentiment and instrumental crime. Controlling for several factors thought to influence temporal variation in crime rates, we find that consumer sentiment had significant effects on robbery and property crime rates over the period that were largely independent of the effects of unemployment and economic growth. We also find that consumer sentiment accounted for a sizable fraction of the crime decline during the 1990s and yields reasonably accurate predictions of changes in the four offenses in 2004 and in two of the four offenses in 2005. We conclude that the effects of collective economic perceptions should become an important focus of future research on crime trends.     

TREND AND DEVIATION IN CRIME RATES: A COMPARISON OF UCR AND NCS DATA FOR BURGLARY AND ROBBERY*

Trends and year-to-year deviations in UCR and NCS data on burglary and robbery are examined for the period 1973 to 1985. We find strong correspondence between year-to-year deviations in UCR crime rates and NCS victimization rates for both crime types. The difference between the two data series lies primarily in their contrasting trends, although there is some evidence that trends in UCR and NCS crime rates have been converging in recent years. Ex post forecasts reveal that the UCR/NCS relationships estimated from the 1973–1985 data continued through 1986 and 1987. Although the UCR rates in 1986 were somewhat influenced by unusual increases in the proportion of crimes reported to the police that year, changes in crime reporting for the period as a whole have had little effect on UCR burglary and robbery rates. We conclude that, within the two serious crime types examined in this study, there is strong consistency between the alternative data sources on variations in crime rates over time.     

Police Strikes and Conventional Crime

Employing FBI "Return A Record Card" data, this study examines the impact of municipal police strikes on reported rates of burglary, robbery, larceny, and auto theft in 11 U.S. cities. Relationships reflecting the view that police presence is essential for crime prevention and social order are examined for variation duration of police strike, city size, and offense category. Overall, analysis yields very limited support for the police presence argument, suggesting that strikes have neither a significant nor a systematic impact on rates of reported crime. Implications of findings for the formulation of police policy are discussed.     

Cashlessness and Street Crime: A Cross-national Study of Direct Deposit Payment and Robbery Rates

Substantial variation in national crime rates suggests social structure and cultural context influence offending and victimization. Several prominent criminological theories anticipate a positive association between the prevalence of cash in a society and its rates of pecuniary crime. We examined the association between one form of “cashlessness” and national robbery rates across nations (n = 67), controlling for several structural covariates of national crime rates. We obtained data on robbery from the United Nations Office on Drugs and Crime, and data on government-based cashlessness from the Global Financial Inclusion Database. We found nations with higher levels of government-based cashlessness had lower robbery rates (β = ?.41, p = .02). We also undertook several sensitivity analyses, including tests for a relationship with commercial cashlessness and for crimes like homicide and burglary. Our results suggest technological advancements that reduce cash in a society may have implications for a nation’s robbery rates.     

Studying New York City’s Crime Decline: Methodological Issues

Methodological issues that must be considered in doing research on the New York City crime drop include the choice of a spatial unit of analysis, the choice of a mathematical representation of the processes responsible for the drop, and the choice of estimators. This paper considers the strengths and weaknesses of a time series analysis of data for New York alone, a panel analysis for the city’s precincts, and a panel analysis for a sample of cities, for studying the drop. The possibilities and limitations of precinct-level data are illustrated with annual precinct data for New York between 1988 and 2001. The paper considers static and dynamic fixed effects panel models estimated in various ways, including difference and systems generalized method of moments. These analyses find no evidence that misdemeanor arrests reduced levels of homicide, robbery, or aggravated assaults. Felony arrests reduced robberies, but only to a modest degree. Most of the decline in these three felonies had other causes.     

Did Post-Floyd et al. Reforms Reduce Racial Disparities in NYPD Stop,Question, and Frisk Practices? An Exploratory Analysis Using External and Internal Benchmarks

Various methodological approaches to constructing external and internal benchmarks have been applied to estimate racial bias in police stop, question, and frisk (SQF) patterns. We apply an external benchmark of the race of the residential population and an internal benchmark of similarly-situated stops to estimate if racial disparities in New York City SQF data were impacted by the Floyd, et al. v. City of New York court settlement. We find that after the settlement, the racial composition of census tracts were no longer significant predictors of the stop rate after controlling for reported crime, socioeconomic factors, and police precincts. We further find that differences in SQF outcomes and hit rates between Blacks and Hispanics and similarly-situated others diminished substantially after the settlement. These findings suggest that court reforms may be an effective method for reducing racial disparities in SQF patterns.     

Juror decision making for juveniles tried as adults: the effects of defendant age,crime type,and crime outcome

This study examined the influences of the crime type (person or property) and the crime outcome (mild or severe) on mock jurors’ verdict and sentencing decisions for adult defendants and juvenile defendants tried as adults. Jurors read a trial summary depicting a defendant charged with aggravated robbery or second-degree burglary. The crimes had either mild or severe damage inflicted on the person or property, and the defendant's age was presented as 14 or 24. Neither the defendant age nor the crime outcome affected jurors’ verdicts; however, jurors were more likely to convict a defendant charged with a crime against a person. Jurors recommended longer sentences for an adult defendant, a defendant charged with a crime against a person, and a defendant charged with a crime with a severe outcome. The discussion explored these outcomes and the role of bias in jurors’ perceptions of defendants.     

Guardianship and residential burglary

Guardianship is a key element in the routine activities approach to understanding crime. This paper examines the effects of guardianship on residential burglary. Several features distinguish these analyses from prior work: 1) both primary and proxy guardianship are included: 2) a more direct indicator of primary guardianship is used; and 3) the effects of guardianship on both the initial risk of burglary and the probability that the crime will be completed are examined. The findings suggest that the effects of guardianship on residential burglary may have been underestimated in prior research. The analyses also show that a complete understanding of the effects of guardianship—especially proxy guardianship—on the entire burglary process will require simultaneous consideration of victimization and offending perspectives.     

American Indians and sentencing disparity: An Arizona test

Although a proliferation of research exists examining the extent to which African American criminal defendants receive more harsh sentences relative to Caucasians, comparatively little research has examined the issue of discrimination in relation to other minority groups. This article examines disparities in sentence length received between American Indian and Caucasian inmates incarcerated in Arizona state correctional facilities. Regression analyses were used to predict the sentences received by American Indian and Caucasian inmates convicted of six crimes (homicide, sexual assault, robbery, assault, burglary, and larceny). After prior felony record and other demographic variables were controlled in these crime-specific models, the crimes of robbery and burglary were the only crimes in which American Indians received longer sentences than Caucasians convicted of the same offense. Caucasian defendants received significantly longer sentences than American Indians for cases of homicide. A defendant's prior felony record was the only variable that consistently increased the length of sentence received by defendants across all types of crime. These findings are discussed and interpreted using various theoretical arguments.     

Crime and the transformation of capitalism

This study investigates factors that enhance criminal behavior. Typically, explanations for increasing crime rates discuss various familial and community attributes; i.e., single parent households and poverty rates. When crime has increased, these attributes are cited as being responsible. This we believe is an incorrect assumption. In particular, we argue the factors that are cited by these authors merely reflect transformations within the greater economic structure. As a result, the familial and community attributes suggested as causing crime are seen as intervening variables; which are either attentuated or amplified in their ability to control criminal behavior by the condition of the economy itself. Within this study, five urban cities (New York, Detroit, Newark, Boston, and Philadelphia) are observed over a twenty eight year period. Structural change is measured by industrial employment and crime is measured by three indices: burglary, robbery and murder. Our investigation reveals a strong relationship between declining industrial employment and increasing crime rates. In addition, we find that the magnitude of this relationship is subject to variation. This variation is dependent upon whether or not the industrial decline experienced was steady or vacilating between high and low levels. These findings support the contention that familial units and other communal organizations are merely intervening variables between large-scale structural changes and criminal behavior. Moreover, it suggests that unless anti-crime efforts (increasing the size of the police forces, increasing state expenditures for law enforcement, etc.) are accompanied by strategies of industrial reorganization, they will have no impact on reducing crime rates.     

A two southern state comparison of the relationship between UCR crime rates and the anticipation of victimization

The purpose of this study is to investigate the relationship between UCR crime rates and a surveyed population’s anticipation of victimization within the next year. Separate surveys were conducted within the states of Tennessee and Texas. In both surveys, self-reported questionnaires were mailed to a random sample of 2,000 individuals drawn from the population of persons holding valid driver’s licenses within that state. A comparison was made between six Part I (rape, robbery, assualt, burglary, theft, and vehicle theft) UCR crime rates of the two states and the expectation of imminent victimization, as shown by the statewide surveys. Several past studies have suggested that there is little relationship between the official incidence of crime and the perceived likelihood of victimization. However, this study presents evidence in support of a positive relationship between UCR crime rates and the anticipation of victimization. In addition, it was found that the greater the anticipation of victimization level the more likely the respondents were to utilize defensive security devices (target hardening).     

Crime,public opinion and trial courts: An analysis of sentencing policy

Much recent research on public opinion and trial courts demonstrates a link between local attitudes and sentencing in highly visible criminal cases. However, such crimes are not typical of most trial court work. Our research examines relationships between public opinion, crime rates, and sentencing in routine cases, including armed and unarmed robbery, burglary, larceny, and possession of narcotics. The research includes over 6000 cases and measures public opinion in all twenty of Florida's trial court circuits. Except for possession of narcotics, no significant correlations were discovered between public opinion and sentencing, but high crime rates generally produced lenient sentences. The research questions the impact of public opinion on most litigation and suggests that judicial elites usually act without concern for local public opinion.     

RACE AND CRIME IN POSTWAR AMERICA: DETERMINANTS OF AFRICAN-AMERICAN AND WHITE RATES, 1957–1988*

The idea that crime and deviance are explained mostly by access to opportunities—especially those provided by employment, income, education, and family stability—is one of the most powerful assumptions about crime in postwar America. However, despite its importance, the actual relationship between opportunity measures and crime during this period remains little understood. while cross-sectional studies of these issues have become common, few longitudinal studies exist and those that do include a limited number of variables. Moreover, despite important differences in the history and experiences of African-Americans and whites during this period, researchers have assumed similar dynamics by race. In this paper, we use annual time-series data from 1957–1988 to examine the effects of economic well-being, educational attainment, and family stability on rates of robbery, burglary, and homicide for blacks and whites. Our results show that these measures have different—usually opposite—effects on black and white crime rates during the period. In general, measures of opportunity have expected effects on white but not black rates. We consider the implications for policy and research.
