The Transparency Stack: LA County's Open-Source Model for Public-Facing Analytics and Trust

Accepted

We will discuss ACE’s (Analytics Center of Excellence) framework for government transparency, detailing how they use tools like Python for shared analysis, GitHub for collaborative code and methodology sharing, and the Justice Hub for public data dissemination. This commitment to open-source not only fosters trust but also directly enables reproducible, high-impact policy analyses, offering a replicable model for other large-scale government data initiatives. The Analytics Center of Excellence (ACE) within the Los Angeles County CEO’s office maintains partnerships with local criminal justice agencies, making information and methodology publicly accessible. This model is underpinned by an open-source mindset.
