Events such as climate change, extreme weather, floods, wildfires, and significant economic changes affect some populations more than others. Populations at Risk is a free tool to easily create reports about populations more likely to experience adverse social, health, or economic outcomes in selected areas of the United States. Variables used include indicators such as race, ethnicity, housing, poverty, and education, among others. Produced in Excel or PDF format, reports may be created at the community, county, or state scale and may compare several geographies. Reports may also be run for American Indian, Alaska Native, and Native Hawaiian geographies. Data are derived from the U.S. Census Bureau and are updated annually.


Urban planners and managers interested in using the Census’ American Community Survey (ACS) to provide social, health, and economic data along with race, age, gender, poverty, and other socioeconomic measures.
