Project on Human Development in Chicago Neighborhoods 2021

The Project on Human Development in Chicago Neighborhoods (PHDCN) is a landmark longitudinal survey study that began over 25 years ago. The 2021 PHDCN is being conducted by NORC at the University of Chicago in collaboration with Robert J. Sampson, Henry Ford II Professor of the Social Sciences at Harvard University and PHDCN-2021 Principal Investigator.

PHDCN is a large-scale, interdisciplinary study of the complex influences exerted on human development by community and family. Directed by researchers from Harvard University—who developed a coordinated approach to the study of human development—it aims to advance science and enrich policy with new strategies for crime prevention and fostering community health.

The purpose of the 2021 data collection is to follow up with a sample of the original PHDCN birth cohorts since the most recent wave of data collection in 2012-13. PHDCN participants all originally lived in the city of Chicago, but some have since moved elsewhere. The study covers a range of topics, including neighborhood safety, interactions with law enforcement, and family health and well-being. Ultimately, the project seeks to assess the effects of violence on long-term social, economic, and health outcomes. Data collection will occur during spring and summer 2021 in three phases, including web, telephone, and in-person survey modes.

Public policy has been influenced by PHDCN findings, including the evaluation of community policing in Chicago, youth violence reduction, and efforts to build community capacity. The project has produced many products for public use, such as data, articles, and the book Great American City: Chicago and the Enduring Neighborhood Effect.
