Our Voice: Citizen Science for Health Equity

The Our Voice Initiative empowers community members to drive change in their local environments. Using the Discovery Tool mobile app, these “citizen scientists” document features of their communities that impact their ability to lead healthy lives. They then review their own findings, prioritize areas for change, and mobilize to promote improvements that will support community health.

This 2-minute video describes the Our Voice approach.

What is health equity?

Health equity means that everyone can live a healthy and vital life, regardless of economic or social circumstances.

Our Voice in Action

Pam Jiner is a Citizen Scientist  and “Street Fighter” who has used the power of data to advocate for infrastructure improvements in her Denver, Colorado community. Through her work as a Program Director for Montebello Walks and as a member of GirlTrek, Pam has engaged over a hundred community members to take action. Using the Our Voice Discovery Tool app gave her an appreciation for the importance of data in driving change. Pam recently presented her work at the 2021 APHA conference. 

Camille Llanes-Fontanilla, Executive Director of SOMOS Mayfair in East San José, speaks about the Our Voice collaboration that helped to shape the organization’s Equity Platform. SOMOS Mayfair supports children, organizes families, and connects neighbors to uplift the dreams, power, and leadership of community and address systemic inequities.


In late 2010, researchers from the Stanford Prevention Research Center identified a number of challenges to healthful living for seniors. In response, the center established Neighborhood Eating and Activity Advocacy Teams (NEATT) to organize seniors and improve their access to healthful food.

The NEAAT Study was conducted by the Healthy Aging Research & Technology Solutions (HARTS) Lab (Director, Dr. Abby C. King) at the Stanford Prevention Research Center, within the Stanford University School of Medicine.

Who are citizen scientists?

Citizen scientists are ordinary people who use community data to activate change.

Our Voice Impact

"This experience has changed my life.  I see inadequacies everywhere I go as it relates to pedestrian access and safety.  I even stop [at] construction sites to remind them to be considerate of the handicapped in our community.  Thank you all so much for this awareness and empowerment to require change."
