About Mapping Criminal Organizations

Analysis of organized crime and criminal violence has been limited by a lack of high-quality data on key attributes of organized criminal groups, including their origins, structure, where they operate, and their alliances and rivalries with one another. The Mapping Criminal Organizations project (MCO) aims to fill this gap for Mexico and develop methods that can be replicated in other countries.

Defining and tracking organized criminal groups is an inevitably complex endeavor. MCO therefore combines methods and sources, from hand-coding data to scraping and processing entire archives using machine learning and natural language processing techniques, to collect and organize data at multiple levels. In its current stage, the project is producing five types of data:

  • State-month data on presence (minor, significant, major), all states, based on hand coding.

  • Municipality-year data on presence (minor, significant, major), some metropolitan areas, based on hand coding.

  • Municipality-year data on presence, all municipalities, based on machine-aided data collection and classification.

  • Group histories tracking the origin, composition, and evolution of criminal groups.

  • Group dyad data on relationship status (allied, enemy) by period.

These elements complement each other. A common core of qualitative research and documented decisions identifies a universe of groups and factions to track through time even as they change names, split and merge, and change affiliations. Hand-coded data helps train and validate our algorithm-based datasets. Automated methods help identify sources and priorities for our hand-coded work.

This project is supported by the Center for U.S.–Mexican Studies at UCSD’s School of  Global Policy and Strategy, the Empirical Studies of Conflict Project, and the Data-Driven Social Science Initiative at Princeton University. It has also received funding from the Mamdouha S. Bobst Center for Peace and Justice at Princeton University.

Patrick Signoret

(Founder and Lead Investigator)

 

Patrick Signoret is a PhD Candidate in the Department of Politics at Princeton University and Research Fellow at UCSD’s Center for U.S.-Mexican Studies. His research interests include public security, organized crime, development, and Latin American politics. His dissertation analyzes competing criminal organizations and state security forces to explain subnational variation in violence trends in Mexico, ultimately seeking to explain when and how order and peace arises in violent criminal contexts.

(Co-founder and Investigator)

 

Marco Alcocer is a PhD Candidate in the Department of Political Science at the University of California, San Diego. His research investigates how government crackdowns affect the activities, structure, and behaviors of criminal organizations, and how, in turn, criminal organizations seek to capture different levels of the government to influence policy and its implementation.

Cecilia Farfan-Mendez

(Field Data Collection Expert)

 

Dr. Cecilia Farfán-Méndez is head of security research programs at the Center for U.S.-Mexican Studies at the University of California, San Diego. Her research examines when and why drug trafficking organizations pursue additional criminal enterprises, the methods used in money laundering, and their different propensities for violence.
