Social Vulnerability Index (SVI) Multi-Geographic Level Dataset 2012-2021 Description This dataset provides a comprehensive compilation of Social Vulnerability Index (SVI) calculations across multiple geographic levels in the United States from 2012 to 2021. The data was generated using the findSVI R package, which extends the CDC/ATSDR SVI methodology to additional geographic levels and more recent American Community Survey (ACS) data. This archive serves as a crucial preservation of social vulnerability metrics, ensuring continued access to this important public health planning tool. Data Coverage Temporal Coverage Years: 2012-2021 Annual data available for all geographic levels Geographic Coverage Geographic levels included: CBSA (Core Based Statistical Areas) Combined Statistical Areas Congressional Districts Counties County Subdivisions Metropolitan/Micropolitan Statistical Areas Places Public Use Microdata Areas (PUMAs) States State Legislative Districts (Upper and Lower Chambers) Census Tracts Variables Core Variables GEOID: Federal Information Processing Standards (FIPS) code uniquely identifying geographic areas RPL_theme1: Socioeconomic Status theme percentile ranking RPL_theme2: Household Composition theme percentile ranking RPL_theme3: Minority Status Language theme percentile ranking RPL_theme4: Housing Type Transportation theme percentile ranking RPL_themes: Overall Social Vulnerability Index percentile ranking year: Year of the SVI data (2012-2021) state: State identifier (two-letter code or 'US' for national level) geo: Geographic level identifier Methodology The dataset was created using the findSVI R package, which: Retrieves 16 demographic variables from the American Community Survey Calculates percentile rankings for each variable Aggregates rankings into four themes: socioeconomic status, household composition, minority status/language, and housing/transportation Generates overall SVI scores through percentile calculations Technical Details File Format: Parquet and CSV (identical data but recomended to use the parquet file as geographic identifiers are type casted as chracter and prevent cutoff of lead `0's` common to census geographic identifiers) Data Structure: Long format with consistent variable names across geographic levels Missing Data: Noted for geographic units lacking component variables Special Cases: DC and Nebraska have specific handling for legislative districts Some geographies don't require state arguments in calculations Usage Notes Data can be filtered by geographic level and year for specific analysis needs Percentile rankings are calculated relative to specified geographic reference areas Some geographic units may have missing values due to incomplete ACS data Users should consider the appropriate geographic level for their specific research needs Citation When using this dataset, please cite: The findSVI R package: Xu, H., Li, R., Bilal, U.
