Worst Crime Areas in Puerto Rico
SET THE HISTORICAL SCENE
Understanding the present‑day crime map requires a look back at the island’s transition from Spanish rule to U.S. territory, the collapse of the sugar economy, and the waves of migration that concentrated poverty in specific barrios.
Each of these turning points left a footprint on community structure, policing practices, and informal economies, creating a layered backdrop that still influences crime rates in places like Río Piedras, Santurce, and Caguas.
