WISQARS Health Equity Data

Notations

** indicates unstable value (<20 deaths);
-- indicates suppressed value (<10 deaths in sub-national geographic areas or missing metric);
--* indicates secondary suppression (value suppressed to prevent derivation of suppressed values)

Notes

• County-level age-adjusted fatal injury rates per 100,000 population are ranked by quartile (low, mid-low, mid-high and high). Age-adjusted fatal injury rates are calculated using the direct method and the 2000 U.S. standard population.
• The Social Vulnerability Index (SVI) percentile ranking values are ranked from 0 to 1 in quartiles as low (0.0-0.2500), mid-low (0.2501-0.5000), mid-high (0.5001-0.7500), and high (0.7501-1.0). Higher SVI ranking values correspond to higher vulnerability.
• The County Health Rankings and Roadmaps data quartiles are based on the values of indicators selected from the dataset. The quartile distribution will vary based on the composition of the variable and what is identifying. For all quartiles, the low represents counties whose data fall in the lowest 25%, representing counties with the lowest vulnerability risk, while the high represents counties whose data fall in the highest 25%, representing counties with the highest vulnerability risk. See here for more information.
• The SVI or CHRR ranking for a county will differ depending on whether national or state-specific data are selected. For state-specific data, counties are ranked relative to other counties in the state. For national-level data, counties are ranked relative to all counties in the United States (including the District of Columbia).
• Beginning in 2022, county-level information on death rates and SVI for Connecticut is not available due to changes in the counties/planning regions. For more information, see the Federal Register.
• The total death count displayed includes deaths to those of unknown age.
• Population estimates are aggregated for multi-year reports to produce rates.

Data Sources

• Fatal injury data are from the National Center for Health Statistics-CDC annual mortality data files.
• Population estimates are from the U.S. Census Bureau.
• Social Vulnerability Index (SVI) data are calculated by CDC/ATSDR using U.S. Census Bureau data.
• County Health Rankings and Roadmaps data are calculated by the University of Wisconsin Population Health Institute.

Detailed fatal injury data are available in WISQARS. Additional information on Social Determinants of Health (SDOH) is also available.

This tool is based on an analytic paper that examined the Social Vulnerability Index and unintentional injury rates in the United States from 2015-2019.
