    The files contained in this archive are the "best" option for Social Vulnerability Index in Southeast Texas. The files are based on the 2020 CDC/ATSDR SVI: "ATSDR’s Geospatial Research, Analysis, & Services Program (GRASP) created the Centers for Disease Control and Prevention and Agency for Toxic Substances and Disease Registry Social Vulnerability Index (CDC/ATSDR SVI or simply SVI, hereafter) to help public health officials and emergency response planners identify and map the communities that will most likely need support before, during, and after a hazardous event."

    This archive includes census tract and block group shapefiles with three selected Social Vulnerability Indices (SVIs) that span a range of methodological approaches and institutional origins. The CDC/ATSDR SVI is a nationally produced, deductive index widely used in disaster management (Flanagan et al. 2011; Flanagan et al. 2018). The Hazard Reduction and Recovery Center (HRRC) SVI, developed at Texas A&M University, was first outlined in Van Zandt et al. (2012) and was validated using post-disaster survey data. SVInsight, developed by the University of Texas, employs an inductive, PCA-based approach, and emphasizes context-specific customization (Bixler et al. 2021; Preisser et al. 2022; Preisser et al. 2023; Preisser et al. 2025). These indices differ in structure, indicator selection, and scale of application, providing a useful basis for comparative analysis in Southeast Texas. In total there are 5 SVI options (census tract CDC, HRRC, and SVInsight+ census block group HRRC and SVInsight). Note that the primary variables to use are C202090012 Index Total CDC Overall Percentile Ranking for Texas H202090012 Index Total HRRC TAMU Statewide Percentile Rank U202090012 Index Total SVInsight Factor Analysis Scaled 0 to 1 Normalized Across Texas For basic analysis the CDC SVI has been determined to be the "best" option. Though, it is recommended to compare results using all 5 SVI options. CDC (2022). CDC/ATSDR SVI data and documentation download.
