Geographic Mapping

In addition to having a better understanding of the people and organizations you are targeting in your planning, also it can be essential to understand where vulnerable populations segments live, work and gather.

Depending on the type of emergency you are responding to or planning for, you may need different data. For example, if you are planning for mass vaccination it would be helpful to have a map of children to determine numbers of pediatric doses. Or maybe you need to schedule interpretation services in a certain geographic area, maps of your top languages by who does not speak English very well, would aid in this effort.


Using 2000 Census data, high level maps were created with assistance of King County’s Geographic Information Systems (GIS) department. We created several different maps including: populations aged 75+ years; populations aged 5 and older with a sensory disability; and linguistically isolated households.

The North Carolina Preparedness and Emergency Response Research Center (NCPERRC) at the UNC Gillings School of Global Public Health developed a quick online resource guide to provide a customized list of resources with accompanying jurisdictional maps to aid local health departments preparedness planning for vulnerable and at-risk populations.
