The value of quantitative analysis for a critical understanding of crime and society has often been questioned. This paper joins the debate by reviewing quantitative evidence on key criminological topics: the causes of crime, public opinion on crime, and the operation and impact of the criminal justice system. This evidence highlights the importance of economic deprivation and racial prejudice and discrimination for understanding U.S. crime and justice and points to the ineffectiveness of the nation's ''get tough'' approach to crime control.

It dominates the discipline of criminology, having characterized 73.1% of the articles published in five leading criminology journals (including 81% of the articles in the leading journal, Criminology) from 1998 through 2002 (Tewksbury et al. 2005). Although the extent of quantitative work does vary by journal (Tewksbury et al. 2005), its importance in criminology and related disciplines is obvious.Despite or perhaps because of this fact, quantitative analysis has long been criticized for several shortcomings. It has been charged with being, among other things, arcane, atheoretical, anti-humanistic, hierarchical, superficial, inherently conservative, and antithetical to a critical understanding of crime and society (Cicourel
