Michael D. Maltz (born 1938) is an American electrical engineer, criminologist and Emeritus Professor at University of Illinois at Chicago in criminal justice, and adjunct professor and researcher at Ohio State University.
Michael Maltz was born in Brooklyn, New York on December 18, 1938. He attended Stuyvesant High School in New York City, graduating in 1955, and Rensselaer Polytechnic Institute, graduating with a degree in electrical engineering in 1959. Maltz earned a Ph.D. in electrical engineering from Stanford University in 1963.
In 1967, his son David Maltz was born, followed by twin sons Joel and Robert -- Joel died in 1974. He married Marcia Farr in 1984. His stepdaughter Julianna Whiteman was born in 1975,
Maltz was a professor (1972–2002) at University of Illinois at Chicago in criminal justice and in Information and Decision Sciences, and is currently an adjunct professor of sociology and researcher at Ohio State University. He was also the editor of the Journal of Quantitative Criminology from 1996 to 2000. In addition, he was a visiting fellow for research and policy studies at the US Bureau of Justice Statistics, from 1995 to 2000.
In 1985 Maltz was awarded the Lanchester Prize [1] by the Operations Research Society of America, recognizing his book Recidivism [2] as that year's "best contribution to operations research and the management sciences published in English". This book also won the Leslie T. Wilkins Award for the Outstanding Book in the Fields of Criminology and Criminal Justice. In 1996 Maltz received a [Fulbright Scholarship,] which he spent at El Colegio de Michoacán in Mexico.
Michael Maltz's research focuses on the application of operations research and data visualization to the field of criminology. In addition to authoring books on recidivism and crime mapping, he has been a strong advocate of ensuring that inferences made from data are not attributable to biases in the data used, nor to the way they were collected, nor to the methods used to analyze them. This interest has surfaced most publicly in his critique of John Lott's More Guns, Less Crime (see "A Note on the Use of County-Level Crime Data" and "Measurement and Other Errors in County-Level UCR Data: A reply to Lott and Whitley" below) based primarily on a detailed analysis of the validity of the Uniform Crime Reports data set that Lott used to draw his conclusions. A further critique, of the way Lott responded to his analysis, was contained in a blog entry.
He led an effort to clean the FBI-collected Uniform Crime Reports crime data, which is available in a zip file on the web from the Historical Violence Database, housed at Ohio State University.
A particularly lucid explanation of the pitfalls of improper use of statistics in social science (and, in particular, criminology) is contained in his article "Deviating from the Mean: The Declining Significance of Significance".
Maltz has published numerous books and articles on techniques for making valid and useful inferences from data. Among his books are two which are available on his academia.edu website (see below):

More Guns, Less Crime is a book by John R. Lott Jr. that says violent crime rates go down when states pass "shall issue" concealed carry laws. He presents the results of his statistical analysis of crime data for every county in the United States during 29 years from 1977 to 2005. Each edition of the book was refereed by the University of Chicago Press. As of 2019, the book is no longer published by the University of Chicago Press. The book examines city, county and state level data from the entire United States and measures the impact of 13 different types of gun control laws on crime rates. The book expands on an earlier study published in 1997 by Lott and his co-author David Mustard in The Journal of Legal Studies and by Lott and his co-author John Whitley in The Journal of Law and Economics, October 2001.

Crime mapping is used by analysts in law enforcement agencies to map, visualize, and analyze crime incident patterns. It is a key component of crime analysis and the CompStat policing strategy. Mapping crime, using Geographic Information Systems (GIS), allows crime analysts to identify crime hot spots, along with other trends and patterns.
In the United States, the relationship between race and crime has been a topic of public controversy and scholarly debate for more than a century. Crime rates vary significantly between racial groups, however, academic research indicates that the over-representation of some racial minorities in the criminal justice system can in part be explained by socioeconomic factors, such as poverty, exposure to poor neighborhoods, poor access to public and early education, and exposure to harmful chemicals and pollution. Racial housing segregation has also been linked to racial disparities in crime rates, as blacks have historically and to the present been prevented from moving into prosperous low-crime areas through actions of the government and private actors. Various explanations within criminology have been proposed for racial disparities in crime rates, including conflict theory, strain theory, general strain theory, social disorganization theory, macrostructural opportunity theory, social control theory, and subcultural theory.
Environmental criminology focuses on criminal patterns within particular built environments and analyzes the impacts of these external variables on people's cognitive behavior. It forms a part of criminology's Positivist School in that it applies the scientific method to examine the society that causes crime.
Operation Ceasefire (also known as the Boston Gun Project and the Boston Miracle) is a problem-oriented policing initiative implemented in 1996 in Boston, Massachusetts. The program was specifically aimed at youth gun violence as a large-scale problem. The plan is based on the work of criminologist David M. Kennedy.
Quantitative methods provide the primary research methods for studying the distribution and causes of crime. Quantitative methods provide numerous ways to obtain data that are useful to many aspects of society. The use of quantitative methods such as survey research, field research, and evaluation research as well as others. The data can, and is often, used by criminologists and other social scientists in making causal statements about variables being researched.
Lawrence W. Sherman is an American experimental criminologist and police educator who is the founder of evidence-based policing.
Cultural criminology is a subfield in the study of crime that focuses on the ways in which the "dynamics of meaning underpin every process in criminal justice, including the definition of crime itself." In other words, cultural criminology seeks to understand crime through the context of culture and cultural processes. Rather than representing a conclusive paradigm per se, this particular form of criminological analysis interweaves a broad range of perspectives that share a sensitivity to “image, meaning, and representation” to evaluate the convergence of cultural and criminal processes.
Criminology is the interdisciplinary study of crime and deviant behaviour. Criminology is a multidisciplinary field in both the behavioural and social sciences, which draws primarily upon the research of sociologists, political scientists, economists, legal sociologists, psychologists, philosophers, psychiatrists, social workers, biologists, social anthropologists, scholars of law and jurisprudence, as well as the processes that define administration of justice and the criminal justice system.

Weisburd was the founding editor of the Journal of Experimental Criminology, and is now the general editor of the Journal of Quantitative Criminology.
Crime displacement is the relocation of crime as a result of police crime-prevention efforts. Crime displacement has been linked to problem-oriented policing, but it may occur at other levels and for other reasons. Community-development efforts may be a reason why criminals move to other areas for their criminal activity. The idea behind displacement is that when motivated criminal offenders are deterred, they will commit crimes elsewhere. Geographic police initiatives include assigning police officers to specific districts so they become familiar with residents and their problems, creating a bond between law-enforcement agencies and the community. These initiatives complement crime displacement, and are a form of crime prevention. Experts in the area of crime displacement include Kate Bowers, Rob T. Guerette, and John E. Eck.
Defensive gun use (DGU) is the use or presentation of a firearm for self-defense, defense of others or, in some cases, protecting property. The frequency of incidents involving DGU and their effectiveness in providing safety and reducing crime are controversial issues in gun politics and criminology, chiefly in the United States. Different authors and studies employ different criteria for what constitutes a defensive gun use which leads to controversy in comparing statistical results. Perceptions of defensive gun use are recurring themes in discussions over gun rights, gun control, armed police, open and concealed carry of firearms.

Experimental criminology is a field within criminology that uses scientific experiments to answer questions about crime: its prevention, punishment and harm. These experiments are primarily conducted in real-life settings, rather than in laboratories. From policing to prosecution to probation, prisons and parole, these field experiments compare similar units with different practices for dealing with crime and responses to crime. These units can be individual suspects or offenders, people, places, neighborhoods, times of day, gangs, or even police officers or judges. The experiments often use random assignment to create similar units in both a "treatment" and a "control" group, with the "control" sometimes consisting of the current way of dealing with crime and the "treatment" a new way of doing so. Such experiments, while not perfect, are generally considered to be the best available way to estimate the cause and effect relationship of one variable to another. Other research designs not using random assignment are also considered to be experiments because they entail human manipulation of the causal relationships being tested.

Duwe holds a bachelor's degree from the University of Kansas and a Ph.D. in Criminology and Criminal Justice from Florida State University.
Public criminology is an approach to criminology that disseminates criminological research beyond academia to broader audiences, such as criminal justice practitioners and the general public. Public criminology is closely tied with “public sociology”, and draws on a long line of intellectuals engaging in public interventions related to crime and justice. Some forms of public criminology are conducted through methods such as classroom education, academic conferences, public lectures, “news-making criminology”, government hearings, newspapers, radio and television broadcasting and press releases. Advocates of public criminology argue that the energies of criminologists should be directed towards "conducting and disseminating research on crime, law, and deviance in dialogue with affected communities." Public criminologists focus on reshaping the image of the criminal and work with communities to find answers to pressing questions. Proponents of public criminology see it as potentially narrowing "the yawning gap between public perceptions and the best available scientific evidence on issues of public concern", a problem they see as especially pertinent to matters of crime and punishment.
Qualitative research in criminology consists of research in the criminology field that employs qualitative methods. There are many applications of this research, and they can often intersect with quantitative research in criminology in order to create mixed method studies.
