West Bay Sacramento / Sierra Central Valley Peninsula Coast East Bay


Why was this site created and how can the site be utilized? 
The concept of the website came from an in-depth community health needs assessment (CHNA) conducted in the Sacramento Region. There are currently six regional maps accessible on the site (click on a region using the map on the left) where users can obtain ER, hospitalization, and mortality rates for a number of diseases and health indicators at the zip code level. The region maps give users several points of view of an area's health status. Users can view chronic diseases and health indicators from a regional level, as well as view rates at more localized levels, i.e. choosing a zip code(s) to generate a detailed fact sheet.

What is the CHVI? 
The Community Health Vulnerability Index (CHVI) is a composite indicator representing socio-economic barriers to health access for communities. It was created by scaling nine variables obtained from Thomson Reuters from 0 to 1. These were summed with equal weights and then ranked. A higher number ranking reflects those areas with the least modeled barriers, or less vulnerability. A lower number ranking indicates the areas with more modeled barriers, or higher vulnerability. The CHVI is the default overlay when a region is selected.

What data is available from this site? 
The region maps are populated with 2011 ER and hospitalization data obtained from OSHPD. The demographic fact sheets contain ER and hospitalization rates broken down by ethnicity/race, gender, and age. The CHVI data and percent of the population that is uninsured in each zip code is from Thomson Reuters.

Where does the data come from? 
The main sources of quantitative data, which populates the region maps, are: Ca. Dept. of Public Health, OSHPD, Thomson Reuters, and the U.S. Census.
