Northwestern’s HDSP PhD equips scholars to trace how families, schools, labor markets, and public programs interact across the lifespan—shaping who thrives and who falls behind. Students fuse developmental psychology, economics, sociology, and data science: coding quasi-experimental evaluations of early-childhood interventions, mining longitudinal tax-linkage panels for mobility trends, and running participatory action research with youth climate activists. A policy-practicum series mentors candidates in translating regressions into legislation, op-eds, and civic-tech dashboards. Graduates become university faculty, foundation scientists, and government analysts spearheading evidence-based reforms.
