Data Sharing

“…Reproducibility is essential for confidence in social scientific results. Since the simplest test of reproducibility is reanalysis by another researcher, the homicide data used to support our conclusions ought to be available for others to examine.”

Roland ChiltonFormer President of the American Society of Criminology

The Center for Homicide Research shares data with qualified individuals and organizations at no cost to the requestor. Each year Center staff is contacted by graduate level students seeking data for research projects and dissertation study. CHR provides research data to individuals who meet criteria as set by the Principal Researcher. This requires that the student in question be enrolled in an educational program. In some cases independent researchers not part of a program will also be considered, as will law enforcement crime analysts, and news journalists. The requestor should be able to show that they have the knowledge and capability to analyze and interpret the data, intelligently and cautiously, taking into account all the advantages and shortcomings of the dataset. Data will be granted on a case-by-case basis. Commercial use is not authorized. Data with all identifiers are available to law enforcement agencies.

To be considered for data sharing, a research proposal must be submitted to the Principal Researcher in a format requested by the Center. Proposals need not be long, but ought to be well thought out. Once approved, the requestor must submit a signed contract (provided by CHR), which lays out the agreement regarding restrictions on data use. This agreement will be provided by Center Staff and will help to ensure security and confidentiality of any sensitive data. The data can then be transmitted to the requestor. Access to foundational data (i.e., the actual reports) is rare, though sometimes available.

Format of the data varies and comes in Microsoft Excel, Microsoft Access, or SPSS. Coding sheets or codebooks will be provided, as will available data documentation. Because some of the data has been collected by third parties, there is no guarantee as to the authenticity or accuracy of that data. It will be received “as is.” Many of the datasets come with victim name, and in some instances, offender name. This facilitates the collection of further records through data linking. This is an advantage since data from ICPSR does not allow for linking under their terms of service. Further information about research sample methodologies should be obtained from the original gatherer of the data.

Data that is available from some other source, such as ICPSR (Inter-University Consortium on Political and Social Research), should be obtained from that source first. Non-CHR datasets or lists are publicly available compilations of data.
