Mortality Dataset :: About This Dataset

The LA 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.


How are mortality data being used?

Mortality Data are derived from information listed on death certificates and are an important source of health information that is readily available to researchers and public health professionals.  This data source has the advantage of being collected continuously and it captures virtually all deaths that occur in Los Angeles County.  The law not only requires that a death certificate be completed for all deaths, but also requires that a physician or medical examiner certifies the underlying cause of death (the disease or condition that initiated the chain of events leading to death).  Cause of death and demographic information in the mortality data can be combined with population data to calculate mortality rates for different medical conditions and for different demographic groups.  Mortality rates are an excellent tool to quickly assess the relative burden of disease across groups and allow government, private, and non-profit groups to make better decisions about resource allocation and program planning.


How often are mortality data updated?

Generally, as soon as new data becomes available. However, there can be a considerable lag time between events occurring and data being processed. For example, mortality data for a given year is usually not cleaned up and ready for analysis until one to two years later. Thus, even though we make every effort to provide you with the most up to date datasets, some of them may contain statistics from one or two years ago. We hope this isn't too great of an inconvenience!


When will more datasets become available to query?

Datasets will be added to LA HealthDataNow! on an ongoing basis. If you cannot find the information you are looking for, please contact the Department of Public Health at phinfo@ph.lacounty.gov for further assistance.
