The Social Vulnerability Index map displays the final Social Vulnerability Index Score and the four theme scores (Socioeconomic, Household Composition, Minority Status, and Housing & Transportation) of each county/census tract ranked against all counties/tracts in the United States. County and tract level data are acquired from the CDC/ATSDR Social Vulnerability Index, 2020.
The Flood Hazard Zones are extracted from the National Flood Hazard Layer, which is a database that contains FEMA’s flood hazard map data. The database contains flood hazard information and supporting data used to develop the information. The primary flood hazard classification is indicated in the Flood Hazard Zones layer.
Flood zones are geographic areas that FEMA has defined according to varying levels of flood risk and type of flooding. For complete information about different flood zone designations, please visit the Definitions of FEMA Flood Zones web page.
Flood Hazard Zone Descriptions:
Floodway: The stream channel and that portion of the adjacent floodplain which must remain open to permit passage of the base flood.
1% Annual Chance Flood Zone: The 100-year or base floodplain.
0.2% Annual Chance Flood Zone: Area of moderate flood hazard, usually the area between the limits of the 100-year and 500-year floodplains, but also shallow flooding areas (< 1 foot) or flood zones for small drainage areas (< 1 square mile).
Area with Reduced Risk Due to Levee: Areas protected by levees from the 100-year flood.
1% Annual Chance Future Considerations: The 100-year floodplain based on anticipated future land-use conditions.
Area of Undetermined Hazard: Area of undetermined but possible flood hazard, typically occurring in counties with partial flood studies.

This layer displays the Cropland Data Layer (CDL) developed by the USDA National Agricultural Statistics Service (NASS). The CDL is a raster, geo-referenced, crop-specific land cover data layer created annually for the continental United States using moderate resolution satellite imagery and extensive agricultural ground truth. The CDL has a ground resolution of 30 meters, and is validated using data from the USDA Farm Services Agency and United States Geological Survey. Historical CDL products are available for use and free for download through CropScape (https://nassgeodata.gmu.edu/CropScape/).
