Health Viewer

The Health Viewer is an interactive, online mapping application (Geocortex Viewer for Silverlight) and contains up-to-date data from a variety of Los Angeles County Department of Public Health programs:

  • 2011 Birth data (e.g. Live Births, Low Birth Weight)

  • 2011 LA County Health Survey data (Adult and Child Section)

  • 2012 Infectious Disease Rates ( e. g. Pertussis, Salmonellosis)

  • 2011 Sexually Transmitted Diseases (e.g. Chlamydia, Gonorrhea)

  • 2010 Age-adjusted Mortality Rates (e.g. Coronary Heart Disease, Stroke)

Users will be able to visualize, query and identify features on the map; as well as print, save and share projects as an image, pdf or as an internet link.  No personal health information (PHI) is available on this site.  All PHI have been removed and data summarized to the health district level (some data are available at the city and community level).


Before using this application, be sure to read the GIS disclaimer below and/or when you launch the Health Viewer application (along the left task pane; click 'x' to close).  If you need additional help, click here: Training Manual and Videos (based on the Los Angeles County GIS Viewer; same Silverlight platform as Health Viewer).
