Purpose
After completing Competency #5, you will be able to identify common types and sources of demographic and community information. You will also be able to define and characterize the population potentially impacted by contamination at a site, including any sensitive and special populations.

Courses and Training Videos
Modules
- Online Public Health Assessment Training (PHAT) - PHAT is a series of online and interactive modules that explain the fundamentals of the public health assessment (PHA) process. For this competency, please review PHAT Module 2.
- PHAT Module 2: Public Health Assessment Overview - In Module 2, section 3, you will find valuable information on how to communicate effectively and tailor your outreach efforts to communities using various communication channels. By exploring this section, you can learn how to work formally and informally with community leaders and organizations.
Guidance
Online Public Health Assessment Guidance Manual (PHAGM)
PHAGM describes methods and resources that you can use to evaluate environmental exposures associated with environmental contamination. You can request the maps and figures displaying information graphically through the ATSDR's geographic information system (GIS).
- Potentially Exposed Populations - This section of PHAGM provides you with information on how to characterize and estimate the number of people in the potentially exposed populations for a site.
- Common Types of Land Use and Natural Resources Information - In this table in PHAGM, you can find a list of the different types of land use and examples of natural resources information.
- Common Types of Demographic and Community Data - In this table in PHAGM, you can find a list of common types of demographic and community data.

Checklist
- Site Information Checklist - Use this checklist to see a list of the issues and medium-specific concerns that you should consider when reviewing data as part of the PHA process.
Geospatial Research Analysis and Services Program (GRASP)
GRASP supports ATSDR by providing geospatial analyses and visualizations. This helps environmental health professionals like you, and communities, to better understand environmental, sociodemographic, and other issues related to chemical exposures across the United States.
- GRASP Figures (Examples) - If you are an ATSDR health assessor, please contact GRASP directly to request services. If you are a health assessor in the APPLETREE program, reach out to your ATSDR Technical Project Officer who will enter a request for GRASP services on your behalf.
