    Violent crimes are costly. Murders, rapes, assaults, and robberies impose concrete economic costs on the victims who survive as well as the families of those who lose their lives, in the loss of earnings and their physical and emotional tolls. Violent crimes also impose large costs on communities through lower property values, higher insurance premiums, and reduced investment in high-crime areas. In addition, violent crimes impose significant costs on taxpayers, who bear the financial burden of maintaining the police personnel and operations, courts, jails, and prisons directed toward these crimes and their perpetrators.

    Fortunately, the incidence of violent crimes in the United States has fallen sharply over the last 20 years. From 1960 to 400 1990 the rates of these crimes rose sharply as did their attendent costs. Over that period murder rates nearly doubled, rates of rape and robbery increased fourfold, and the rate of assault quintupled. Since the early 1990s, however, rates of most violent crimes have been cut nearly in half. (see Figure 1)

    The good news: Falling crime rates

    Yet rates of most violent crimes in the United States remain high compared to the 1950s and 1960s and to other advanced societies today. The U.S. murder rate, for example, has fallen to a 50-year low, but that rate is still nearly three times the level in Canada and more than four times the level in the United Kingdom. Among all of the world’s developed countries, the United States today, on a per capita basis, ranks second in murders, fourth in rapes, and sixth in robberies.

    The Bureau of Justice Statistics reports that the majority of all violent crimes involve the use of weapons, and in two-thirds of all homicides and 41 percent of all robberies, the weapon is a handgun. (see Table 1)

    Most violent crimes involve weapons

    Moreover, from 2005 to 2010 the nationwide incidence of homicides declined by 12.5 percent, the number of robberies decreased by nearly 9 percent, and the number of aggravated assaults declined by 7 percent. The share of crimes committed with guns in all three categories, however, remained constant.

    By most measures, violent crime continues to impose significant costs on Americans and their communities. The costs borne by the American public for this level of criminal activity are significant. Medical care for assault victims, for example, costs an estimated $4.3 billion per year. We spend $74 billion per year on incarcerating 2.3 million criminals, including some 930,000 violent criminals.

    Moreover, the costs of the pain and suffering borne by the victims of violent crimes is several times greater than the more direct costs of those crimes. As a result, successful efforts to reduce violent crime can produce substantial economic benefits for individuals, communities, and taxpayers.

    This report presents the findings and conclusions of a yearlong project to examine and analyze the costs of violent crimes in a sample of eight major American cities and estimate the savings and other benefits that would accompany significant reductions in those crimes. This analysis draws on data pinpointing the incidence and location of murders, rapes, assaults, and robberies. The data were provided by the police departments of Boston, Chicago, Dallas, Houston, Jacksonville, Milwaukee, Philadelphia, and Seattle.

    We examined a broad range of both direct and intangible costs associated with those violent crimes based on their incidence in each of the eight cities in 2010. The direct costs reported here are those borne by the residents and city governments of the eight cities, although additional costs are also borne by state and federal governments and the taxpayers who finance them. Finally, we calculated the benefits to those residents associated with substantial reductions in violent crime, including the impact on residential home values and a variety of savings to the city governments.

    In today’s tight fiscal and economic environment, the mayors and city councils of every city—along with state and the federal governments—are searching for ways to reduce their spending and expand their revenues. The common challenge is to achieve sustainable fiscal conditions without hobbling government’s ability to provide the vital goods and services that most Americans expect, all without burdening businesses and families with onerous new taxes. This analysis provides another way available to many American municipalities: Secure budget savings, higher revenues, and personal income and wealth gains by reducing violent crime rates.

    To calculate the extent of those savings and benefits, we analyze a broad range of direct costs associated with the violent crime in the eight cities sampled here. These direct costs start with local spending on policing, prosecuting, and incarcerating the perpetrators of those crimes. These costs also encompass out-of-pocket medical expenses borne by surviving victims of violent crime as well as the income those victims must forgo as a result of the crimes. These costs also include the lost incomes that would otherwise be earned by the perpetrators of violent crimes had they not been apprehended—as distasteful as it is to calculate the foregone income of rapists or armed robbers who are arrested, convicted, and incarcerated. These direct, annual costs range from $90 million per year in Seattle to around $200 million per year in Boston, Jacksonville, and Milwaukee, to more than $700 million in Philadelphia and nearly $1.1 billion for Chicago.

    This report also examines certain intangible costs associated with violent crime, including the pain and suffering of the surviving victims of violent crime and the costs to the families of murder victims. Across the eight cities examined here, the total annual costs of violent crimes, including these intangible costs as well as the more direct ones, range from more than $300 million per year in Seattle to more than $900 million in Boston, to some $3.7 billion per year in Philadelphia and $5.3 billion for Chicago.

    Based on this analysis we also estimate the budgetary savings that each of the eight cities should expect to achieve if their rates of violent crime declined by either 10 percent or 25 percent. These savings include lower expenditures on law enforcement and the justice system, as well as the additional revenues that each city could expect to collect from applying local taxes to the income earned by those who otherwise would have been victims or perpetrators of those crimes.

    All told, the estimated savings for municipal budgets from a 25 percent reduction in violent crime range from $6 million per year in Seattle to $12 million per year in Boston and Milwaukee, to $42 million per year in Philadelphia and $59 million for Chicago. We also estimate the value of other benefits associated with reduced rates of violent crime, including lower out-of-pocket medical costs for those who otherwise would have been victims as well as their averted pain and suffering.

    The largest economic benefits, however, arise from the impact of lower rates of violent crime on the housing values in the cities sampled here. To estimate this effect, we use data covering several years on the incidence of violent crimes by zip code in each city and changes in housing values in the same zip codes over the same period. Five of the eight cities were able to provide data by zip code covering at least six years. Our analysis of those data found that a reduced incidence of murders in a particular zip code is followed by a predictable and significant increase in housing values in the same zip code in the next year.

    On average, a reduction in a given year of one homicide in a zip code causes a 1.5 percent increase in housing values in that same zip code the following year. We applied these findings to available data on the value of the housing stock in the metropolitan areas of all eight cities. The estimated increases in the value of the housing stock for the eight cities and their immediate metropolitan areas, following a 10 percent reduction in homicides, range from $600 million in Jacksonville and the surrounding area to $800 million in the Milwaukee area, to $3.2 billion in Philadelphia and the surrounding suburbs, and $4.4 billion in the Boston area. Unfortunately, inconsistent reporting of other types of violent crime—rapes, assaults, and robberies—preclude a reliable analysis of the impact on housing values of changes in the incidence of those crimes.
