ASTHO’s Public Health Legal Mapping Center

Public health and law are interwoven, shaping how communities interact and people experience the world around them. Legal mapping is the scientific process of analyzing state laws concerning a legal topic at either a particular point in time (cross-sectional) or its change over a period (longitudinal). This page features ASTHO’s legal mapping work to plot the legal landscape for public health priorities. These interactive maps and tables aim to explore trends, track shifts in the law over time, and assist in understanding intricate public health law and policy questions.

Currently, ASTHO legal maps cover policies to prevent or reduce overdose and to strengthen public health infrastructure.
