Query SystemThe L.A. HealthDataNow! project was established by epidemiologists of the Department of Public Health (DPH) to close the gap on data accessibility. Utilizing tools commonly used by DPH analysts, programs can not only provide their data in an automated and flexible manner, but they can also incorporate automated statistical analysis into the query system. Ultimately, the goal of this project is to extend this query system to all DPH programs that have similar interests to make their public health data more accessible.
