IGNITE Study
Brief
Persistent differences in health across neighborhoods remain a major public policy challenge in the United States. In many cities, people living in under-resourced areas experience poorer physical and mental health, greater economic hardship, and shorter life expectancies than those in more affluent neighborhoods, even when they live just a few miles apart. These differences arise from interconnected social and economic conditions—including limited access to quality services, economic insecurity, and environmental stressors—that operate at multiple levels and across time. Addressing such complex disparities likely requires multiple complementary investments that improve both the places where people live and the resources available to them, rather than relying on single, isolated interventions.

About the Project
The IGNITE Study—a joint project between Opportunity for Health, the Penn Urban Health Lab, and multiple community partners—is testing this “big push” approach through a cluster-randomized controlled trial in 58 low-income neighborhoods in Philadelphia, where life expectancy gaps of up to 20 years have been documented. We, along with our community partners, are implementing a multi-component intervention that combines place-based improvements, such as vacant lot greening, tree planting, and trash removal, with financial supports at the household level, including financial counseling, a one-time microgrants, help accessing public benefits, and tax preparation services. By working across community, organizational, and individual levels, the study aims to tackle the root causes of health inequities through coordinated environmental and economic investments.
IGNITE is designed to measure a range of health, economic, and social outcomes over a 24-month follow-up period, including overall health status, psychological distress, access to care, financial well-being, food security, and crime. The primary health outcomes—such as self-rated health, days of impaired health, and mental health indicators—will be assessed alongside economic and social measures like participation in public support programs and time spent in green spaces. Results from the trial are expected after the study’s estimated completion in mid-2026, and will help clarify whether bundled, place-based and financial strategies can meaningfully improve well-being and reduce disparities at the neighborhood level.
IGNITE is funded by the National Institutes for Health.
