A Behavioral Study of the Radicalization Trajectories of American "Homegrown" Al Qaeda-Inspired Terrorist Offenders, 2001-2015 [UNITED STATES] (ICPSR 36452)
These data are part of NACJD's Fast Track Release and are distributed as they were received from the data depositor. The files have been zipped by NACJD for release, but not checked or processed except for the removal of direct identifiers. Users should refer to the accompanying readme file for a brief description of the files available with this collection and consult the investigator(s) if further information is needed.
The study aimed to develop and empirically test a dynamic risk assessment model of radicalization process characteristics of homegrown terrorists inspired by Al Qaeda's ideology. The New York Police Department (NYPD) model developed by Mitchell D. Silber and Arvin Bhatt was chosen as the basis for creating a typology of overt and detectable indicators of individual behaviors widely thought to be associated with extremism. Specific behavioral cues associated with each stage of radicalization were coded and used to estimate the sequencing of behaviors and the duration of the average radicalization trajectory. Out of 331 homegrown American Jihadists (Group A), 135 were selected for further examination of their radicalization (Group B). Data were collected from public records ranging from social media postings by the offenders themselves to evidence introduced in the adjudication of the offenses for which the offenders were incarcerated. Life histories were compiled for Group B, whose detailed biographies were used to chart the timelines of their radicalization trajectories.
The collection includes an Excel file which contains one data table for Group A (10 variables, n=331) and two data tables for Group B (32 variables, n=135 and 5 variables, n=135, respectively). An accompanying codebook file details the variables in these tables. There is also a document with approximately 1 page narratives for each of the 135 individuals in Group B. A file containing a key indicating the names of the subjects is not available with this collection.

Terrorism and Preparedness Data Resource Center (ICPSR 192)
The Terrorism and Preparedness Data Resource Center (TPDRC) is housed at the University of Michigan's Inter-university Consortium for Political and Social Research (ICPSR). TPDRC archives and distributes data collected by government agencies, nongovernmental organizations (NGOs), and researchers about:
The nature of intra- (domestic) and international terrorism incidents, organizations, perpetrators, and victims
Governmental and nongovernmental responses to terror, including primary, secondary, and tertiary interventions
Citizen's attitudes towards terrorism, terror incidents, and the response to terrorism
It also organizes and streamlines access to extant research and administrative data from across the world that are relevant to the study of terrorism and the response to terrorism for descriptive and scientific analysis by academics and researchers.
The TPDRC also includes the Terrorism and Preparedness Survey Archive (TaPSA). As part of TPDRC, TaPSA archives national and international survey data and related research materials about terrorism, homeland security, and preparedness.
