Ep 12. Crime data isn't great. Dr. Matt Nobles explains how a strong research methodology can address these problems.

People assume there is good data about crime available from official sources. This isn't true and most crime data is a mess which is why I maintain a database of school shootings.

Host: David Riedman, founder of the K-12 School Shooting Database

Guest: Dr. Matt Nobles, Criminologist and Methodologist, University of Central Florida

  • All research projects start with finding data or evidence, and then applying a research methodology to answer the question.

  • Federal crime data is incomplete, published ~2 years after crimes occur, and doesn’t add up when multiple sources are cross-referenced.

  • Before 2000, there wasn’t a federal mandate for colleges and universities to report crimes on campus. Dr. Nobles’ first major research project was analyzing unreported sexual assaults on campus.

  • There is not a Higher Education School Shooting Database because it’s very hard to define the boundaries of a university campus (e.g., is a shooting during college night—specifically targeting college students—at a bar next to campus a higher ed school shooting?)

  • Without standardization of crime data, we don’t know the characteristics of crimes, we can’t measure the impacts, we don’t know if rates are going up/down, and we can’t develop useful public policy.
