Finalist and winning proposals for the Data for Security Contest Bogota

DUFLOS, a team formed by Jose Luis Beltrán Gonzalez, Helen Granados Rodriguez and Andrés Felipe Leguizamón López, Economics students, under the supervision of Professor Sergio León Álvarez Fernández, developed the CHANGUA Index (Adjusted and Normalized Heterogeneous Calculation with a Gender, Urbanism and Business Activity perspective), a tool that uses item response theory (MIRT) and spatial statistics (Moran Index and Lisa Maps) to perform territorial analysis by neighborhoods of the perception of insecurity in Bogotá.

DATANOVA, a team formed by Helen Stefany Penagos Galvis, Sharek Marin and Valentina Rodríguez Niño, Data Science students, and under the mentorship of Professor Alber Ferney Montenegro Vargas, conducted an analysis of the relationship between perception of insecurity, victimization and business climate in Bogota, using data from the Perception and Victimization Surveys (EPV) and Business Climate (ECN) for the period 2022 and 2023. The report concludes by recommending the implementation of specific security programs, tailored according to business size and sensitive to gender differences, to improve cooperation between businesses and authorities, thus strengthening a safe and equitable business environment in Bogota.

LA RED, a team formed by María Fernanda Contreras Acevedo, Brayan David Flórez and Fernanda Forero Arbeláez. Based on the 2024 Strategic Corridors, the subjective and objective perception of insecurity in relation to works such as the First Metro Line and the extension of Calle 13 was evaluated, differentiating effects by sex and forms of victimization. With the Mobility and Urban Environments Survey, the experience of citizens in intervened areas was incorporated, observing changes in mobility and trust. The Business Climate Survey made it possible to explore the impact of victimization on business security decisions. The approach allows capturing individual perceptions and population trends, in dialogue with studies on urban planning and citizen security.

DATA WATCHWOMEN, a team formed by Juan Andrés Escobar Mora, Brayan David Trujillo Perdomo and Nicol Juliana Puerta Suarez, students of Statistics and Graphic Design, and the tutoring of the teacher Denize Torres. The purpose of their work was to examine how perceived security and crime rates affect the business environment in Bogota, from a gender perspective. From the proposed data and secondary sources, they found how victimization and the perception of insecurity affect the stability and growth of companies, especially in those where women occupy leadership positions.

DATAGÉNERO, a team formed by Sharon Violeta Cuellar Centeno, Valentina Rivera Piedrahita, Catalina Escobar Rodríguez, students of Statistics, Sociology and Graphic Design, and the tutoring of professor Lida Fonseca. The study analyzes gender differences in the reporting of crimes in the business environment. Based on data from the Perception and Victimization Survey (EPV) 2023, it examines the factors that influence the decision to report, showing that women report less frequently than men. This difference is mainly explained by three factors: fear of reprisals, distrust of institutions and the perception of impunity. These three axes form the basis for the study's recommendations. In order to identify patterns and trends, explanatory statistical models were applied, with the aim of proposing strategies to strengthen security and confidence in reporting mechanisms.
