Crime is down in America.  Violent crime, including homicide and robbery, have all fallen dramatically throughout the 1990s.  Property crime is down substantially, including the categories of motor vehicle theft and burglary.  No matter which indicator one uses, whether the National Crime Survey or the Uniform Crime Reports, crime is down.  Moreover, no matter how one analyzes the data, the one consistent factor that everyone has to agree upon is that crime, or at least crime rates, are down.  For instance, the latest available data from the Federal Bureau of Investigation’s Uniform Crime Reports shows that all categories of crime have continued this downward trend (F.B.I. 2000).  The rate of crime per 100,000 population from 1998 to 1999 dropped 7.6 percent.  The rate of change from 1995 to 1996 was down 3.6 percent, to 1997 it was down 6.6 percent, to 1998 it was down 12.4 percent, and to 1999 it was down 19.1 percent (F.B.I. 2000).  And in relation to overall crime trends, according to the F.B.I., the “crime index rate for 1999 is the lowest–4,267 per 100,000 of the Nation’s inhabitants–since 1973” (F.B.I. 2000, 6).  Everyone has come to recognize and celebrate this downward trend.  However, while analyzing this data, identifying the downward trend, and recognizing what is assuredly a remarkable and unprecedented phenomenon is important, the truly important question that one must ask is “why?”
 

This author has been asked on a number of occasions by family and friends what has caused the downward trend.  Although not necessarily the most polite response, I usually answer their question with a question by asking them what they think has caused the downward trend.  In general, the answers I receive include more police officers on the street, community policing (which I always enjoy hearing), building more prisons, and that we “won” the war on drugs.  Eventually they return to their original question and I usually answer the key is demographics.  For the most part they find it interesting, but have little desire to go beyond basic understandings of age, gender, and race.  In regards to my criminal justice students I tend to expand upon what I mean by demographics, which has included the changing makeup of age, gender, and race, but  also the changes in politics, economics, and the social environment.  We explore the increase in political action regarding crime during the 1980s and 1990s (policies for more cops, more courts, more prisons), the economic boom of the 1990s (which has helped fund more cops, more courts, and more prisons), and the changing makeup of the drug culture, domestic violence, gun control, and a host of other social conditions that have come to bear on the changing “demographics” which have contributed to this downward trend.  In sum, we analyze a very complex but interrelated web of events that have contributed to this intriguing phenomenon.
 

Although this type of answer, whether the simple approach (it’s demographics) or the more detailed approach (it’s a combination of factors), have seemed to be somewhat accurate in relation to the evidence available, much of it has been theoretical abstraction of existing data, until now.  In the fall of 2000, Cambridge University Press published an edited collection of all-new research attempting to explain this phenomenon and it is appropriately titled, The Crime Drop in America.  It is edited by two well respected individuals in the field, Alfred Blumstein (Director of the National Consortium on Violence Research) and Joel Wallman (Program Officer at the Harry Frank Guggenheim Foundation), and features articles written by such noted researchers as William Spelman, Richard Rosenfeld, John Eck, and James Alan Fox.  This publication provides both realistic and rational explanations for the downward crime trend by relying on in-depth reviews of recent research that have analyzed crime data, combined with cutting-edge research of its own, to give what is clearly the most definitive explanation to the question “why?”  Up-front, this book is designed to become the seminal work in understanding the “crime drop” and it lives up to its expectations.
 

If anyone is familiar with Alfred Blumstein’s writings or presentations, they will find familiar territory in the first two chapters.  In Chapter one, co-authored with Joel Wallman, the authors provide a general overview of the crime drop, a review of the major sources of crime data, and they couch the crime-drop in terms of a four-decade change in the crime trends.  They then explore the various roles that certain factors have played in the recent crime drop experiences during the 1990s, setting the stage for the chapters that follow.  In the second chapter, Blumstein  provides a disaggregated analysis of the violent crime trends in America by focusing primarily on both homicide and robbery.  A number of the possible factors explaining both the rise in crime during the 1980s and the subsequent drop in the 1990s are explored and these include changing demographics and the role that handguns and drugs played during this time period. Blumstein concludes, in general, that the increase in the 1980s had to do with the escalating rates of homicide by and against black males and an increase in the use of handguns by this same group.  Reductions in the prevalence of this phenomenon than, have contributed to the reduction in crime during the 1990s.
 

The Blumstein article provides an excellent lead-in to the next chapter (Chapter 3) which is authored by Garen Wintemute who presents a learned article consisting of a detailed analysis of recent research conducted on gun violence.  It does this by disaggregating the various studies into categories that assesses the victims of gun violence, the perpetrators, the places they occur, the weapons used, and the access that people (mainly juveniles) have to guns.  It then looks at guns as a consumer product by reviewing the available research conducted on the manufacturers, sellers, and consumers of guns to understand how guns have come to be utilized in crimes.  The chapter then concludes with an assessment of what works, what doesn’t, and what looks promising, such as restrictions on gun sales, gun bans, and comprehensive intervention programs like those implemented in Boston, Massachusetts.   One comes away from this chapter not so much with a definitive explanation of how much gun interventions have reduced crime in the 1990s, but rather with a fuller understanding of the various relationships between guns and crime and the multiple points of intervention that have been and can be taken.
 

Perhaps one of the most controversial chapters is the following chapter authored by William Spelman which attempts to understand the relationship of prison expansion with the crime drop (Chapter 4).  This chapter is not necessarily controversial in and of itself, but it deals with an issue that has remained controversial since it was first proposed and that is the elasticity of incarceration, which Spelman defines as “the percentage change in the crime rate associated with a one-percent change in the prison population.”  Spelman does an excellent job reviewing all of the key studies, both simulation and econometric studies, conducted over the past decade utilizing both national and state data.  He then shows from these studies that the elasticity ratio for violent crime tends to range from -.10 to -.50 with a general assessment of -.30 being the most probable figure.  This means for every one percent increase in prison population, crime rates would (or should) drop by thirty percentage points.  Spelman then expands upon past research by taking into consideration various factors related to imprisonment over the past two decades as well as the changes in adult violent crime and concludes that the crime drop would have most likely occurred without the prison expansion of the 1980s and 1990s, but it would have been approximately 27 percent smaller than it has been.  Spelman’s article is then the only article in the book to attempt to definitively state that approximately 25 percent of the crime drop can in fact be explained by the prison build-up.
 

Chapter five, authored by Richard Rosenfeld,  returns to the issue of homicide, but focuses more exacting on adult homicide from 1980 to 1995.  The article, in a way, becomes a reaffirmation that the demographic of age is largely responsible for the drop in the crime rate because of the aging baby boomers coupled with the desistance phenomenon.  Rosenfeld also reviews other demographics and, like Blumstein, acknowledges the impact of black male victim-offender rates creating a rise in homicide during the 1980s, then a decline in the 1990s.  Rosenfeld also reiterates the effect that incarceration had on the specific crime of homicide, echoing Spelman’s article with his analysis of homicide.  However, Rosenfeld then proposes that some of the drop in crime was related to declining domesticity and intimate partner homicide.  He argues that the decline in marriage during this time period reduced the level of intimate partner homicide, thus contributing to the reduction in homicides experienced in the 1990s.  The theory, while plausible, falls short of proof for the very reason the author cites, “reliable trend data on the number of boyfriends and girlfriends in the population do not exist, and so it is difficult to determine whether the rate of nonmarital homicide is rising or falling” (p. 152).  In other words, although marital rates of homicide may be falling, we do not know for a fact if nonmarital rates increased during this same time period.  This seems to be too far an advancement for current research on domestic violence and homicide rates and perhaps a more simplistic theory (and one more likely to be supported by evidence) such as domestic violence awareness during the 1980s and 1990s has successfully helped to reduce the occurrence of intimate partner homicides, would have been more appropriate.  This is, as far as the author can tell, the only aspect of the entire publication that postulates a theoretical explanation for the crime drop without good quality research to support its assertions.  While the theory remains intriguing, it lacks the necessary evidence to be included as a key explanation to the crime drop.
 

The next chapter (Chapter 6) is co-authored by Bruce D. Johnson, Andrew Golub, and Eloise Dunlap and analyzes the relationship between drugs and inner-city violence in New York city.  Although they use a case study example as the basis for their article, they continually tie the relationship of drugs and violence to what was occurring throughout the United States in the 1980s and 1990s.  Their findings show a trend in the use of three specific drugs: heroin, cocaine, and marijuana.  What the authors conclude is that the use of these three drugs has gone in cycles.  They dub the 1960s as the “heroin injection era,” the 1980s as the “cocaine/crack era,” and the 1990s as the “marijuana/blunt era.”  Since more violent crime has been associated with heroin and crack then with the use of marijuana they demonstrate that violent crime associated with heroin rose in the late 1960s and violent crime associated with cocaine, specifically crack, rose in the mid- to late 1980s.  Enter the 1990s, the preferred drug by those born in the 1970s has been the use of blunts (marijuana rolled into cigar leaves), for which marijuana is not generally associated with violent crime.  As a result, the authors argue that this fact, coupled with other social factors associated with drug use (e.g., domestic violence, guns, etc.) has contributed to the reduction of crime in the 1990s.
 

The next chapter (Chapter 7), co-authored by John E. Eck and Edward R. Maguire, looks at the claims that the police, through such programs as community policing, adding 100,000 cops, and zero-tolerance policing; are responsible for the reduction in crime.  They acknowledge the long-held proposition that the police do not directly effect crime rates at the beginning of their article, but then argue that this proposition needs to be revisited.  In doing so, they first analyzed key studies over the past thirty years regarding this relationship and were forced to conclude that there is no consistent body of evidence that explains the impact of the police.  Second, they analyzed research conducted on many of the current innovations in policing to determine if there has been any consensus on their relationship with reducing crime and again the authors conclude there is no consistent evidence to be found.  Finally, they re-analyze what impact police might have on crime and conclude that, if any, it is when they focus on a specific place or on a specific  group of people.  By and large, they conclude, police do not have an independent impact on crime (such as through community policing, etc.) but are most likely one variable among numerous social variables.
 

The next chapter (Chapter 8), authored by Jeff Groger, utilizes an econometric model to explain the recent downturn in violent crime rates.  His analysis takes a look at well traveled territory, namely the relationship between the labor market and crime.  Utilizing an age-wage profile, what he finds is that “when wages are low, crime is high, and when wages are high, crime is low” (2000, 272).  Groger immediately acknowledges the deficiencies of such modeling, but argues for its use to allow the reader to begin thinking in terms of the labor market.  He then explores the drug market and demographic variables associated with violent crime.  At best, his findings are suggestive that the labor-market and drug-market assisted in the crime drop.  In other words, with a better economy in the 1990s, more young people were able to share in the economic benefits, hence choices to enter the labor-market and not the drug-market were increased.  Therefore, crime dropped because of the expanding economy.
 

The final chapter (Chapter 9), authored by James Alan Fox, looks at the relationship between demographics and U.S. homicide during the past thirty years.  Analyzing the variables of gender, race and age, Fox concludes that demographics did it fact play a part in the crime drop of the 1990s, but not necessarily a large and significant one.  Buried within this article is a very interesting analysis of the recent and controversial findings, still yet unpublished by Donohue and Levitt, that hypothesized the crime drop could be attributed with the legalization of abortion by the Supreme Court case Roe v. Wade.  A number of factors, all related to the demographics utilized in Fox’s analysis, demonstrates that the findings, while interesting, are in need of far more research to make such sweeping claims.  Fox then looks to the future using demographic forecasts and, attempting to be more realistic than most claims of a future crime wave, does argue that crime at some point in the near future, will most likely begin to take an upward trend.  After all, nothing good can last forever and it is unrealistic to believe that the trend could continue to the point we would have no crime or even “negative” crime.
 

As stated, the book ends with the chapter by Fox on demographics and homicide and tends to leave one thinking about a whirlwind of explanations.  The reader is left with the assessment that 25 percent of the drop was the result of the prison expansion movement and that the significant drops in crime during the 1990s was also a result of changing drug use, increased gun control/intervention efforts, changes in adult and juvenile homicide rates, changes in policing, the labor market, and basic demographics.  In other words, the crime drop was caused by a host of key factors mostly resulting from changes in political, economic, and social conditions, thus creating an intricate web of causes affecting the crime rates since 1992.  While this perception is most likely very accurate and there is some evidence now to support this assessment, thanks to the publication The Crime Drop, one is left wondering which was more important and which direction should we take to continue this trend or, at a minimum, hold the line at which we stand?  The publication then, would have been better served had Blumstein and Wallman pulled the findings together or concluded with an overall assessment.  Despite this one inadequacy, this book should find its way into the hands of anyone interested in understanding why crime has dramatically fallen over the past eight years.  More importantly, however, this book should find its way into the hands of every criminal justice professor teaching and explaining to students the causes of this downward trend.  This is currently, succinctly stated, an important book.
