Learn more about what makes DataSF tick
Our mission is to empower use of data. At DataSF, we seek to transform the way the City works through the use of data. We believe use of data and evidence can improve our operations and the services we provide. This ultimately leads to increased quality of life and work for San Francisco residents, employers, employees and visitors.
We are a data-driven City. Leadership and employees use data to continuously improve City services and operations. City staff has the support, skills and capacity to collect, manage, and use data effectively and efficiently. Our data is understood, documented and of high quality. Our data infrastructure provides data that is usable, timely, and accessible. Published data supports broad and unanticipated uses of City Data and supports trust, transparency and accountability.
These are the core team that work on DataSF programs, services and initiatives related to open data, data analytics and data science.
