Purpose: The Vulnerable and At-Risk Populations Resource Guide (VARP) is intended to help decrease the time it takes for local health departments to identify and locate relevant information regarding at-risk populations in order to assist their planning and preparedness activities. Tool Description: The VARP Guide is an online resource to assist local health departments preparedness planning for vulnerable and at-risk populations. Based on individual responses to a short series of questions, the VARP Guide provides links to population-specific resources and tools to help local health departments work with vulnerable population groups to build or maintain partnerships. The tips and resources contained in the VARP Guide provide information related to: 1. Identifying Vulnerable and At-Risk Populations 2. Planning for Vulnerable and At-Risk Populations 3. Building Community Partnerships 4. Customizing maps to illustrate vulnerable populations at the census tract level according to the Social Vulnerability Index for Disaster Management (Flanagan et al. 2011) Who should use it?: The VARP Guide was designed for use by local health department staff responsible for vulnerable populations planning and response as well as their partners. Any jurisdiction can use the tool, but it is most helpful for smaller/low resourced departments. In addition, the VARP Guide is currently being implemented in North Carolina, Washington State (Seattle), New Mexico, West Virginia, and Georgia. If implementation in other states is funded, it could be expanded to all locations covered by the US Census. Benefits: By making it easier for local health departments to identify where at-risk populations are more prevalent, it is ultimately hoped that they will receive more attention. By doing so, they can be better served during an emergency scenario
