Populations and Vulnerabilities

Populations and Vulnerabiltities Indicators

The Tracking Network uses several national sources, including federal agencies, to obtain state and local data about population characteristics. This information is based on populations as a whole rather than individual members of a particular population. Therefore, individual health risk factors are not included in this information.

Demographics

This indicator includes population estimates (number and percent) of people by race, ethnicity, age, gender, single-parent households, speaking English less than “very well’, and aged 65 years and older and living alone. Data are presented at Census tract, county, and/or state level for all states.

Health Status

This indicator includes data on number and percent of people uninsured; number and percent of people over age 5 years with a disability; and percent of population diagnosed with diabetes. Data are presented at Census tract, county, and/or state level for all states.

Life Expectancy at Birth

This indicator shows the average annual life expectancy at birth for a population over a 5-year period. Data are presented at county and state level for all states. These data are estimates and cannot be used to predict an individual's life span.

Social Vulnerability Index

This indicator shows relative vulnerability of every U.S. Census tract on 14 social factors including poverty, lack of vehicle access, and crowded housing. The factors are grouped into four related themes. Each Census tract receives a ranking for each variable, each theme, and an overall ranking. These data can be used by public health officials and local planners to better prepare communities to respond to emergency events like severe weather, floods, disease outbreaks, or chemical exposure. Depending on the year, data are available at the Census tract and county level for all states.

Socioeconomic Status

This indicator includes data on poverty, household income, employment status, and high school (or equivalent) graduation status. Data are presented at Census tract, county, and/or state level for all states.
