BALTIMORE, MD, May 13, 2025 – As communities across the United States continue to confront the devastating toll of mass shootings, new research reveals a staggering economic dimension to these tragedies.

This will begin the decennial effort of congressional mapping when state legislative or independent redistricting committees draw maps in anticipation of the midterm elections in 2022. The high stakes involved in drawing such maps typically lead to partisanship divides, making the entire process highly contentious and controversial.
