Data to Support Coastal Adaptation & Resiliency
The following geospatial datasets and mapping viewers can help inform many types of activities including comprehensive and hazard mitigation plan updates, vulnerability assessments; stormwater or parks and recreation plans development; flood zone workshops, and other events serving both technical and general audiences.
These data sources should supplement the current and most accurate data found at the local level in the different municipal or county departments (e.g., planning, geographic information systems (GIS), public works, parks and recreation, etc.). If using data to support policy or other programs, be sure to examine, understand, and be transparent about the metadata or 'data about the data' such as source, resolution, geographic projection, update frequency, etc.

Social Vulnerability:
Social vulnerability, often expressed as an index, can be measured by and consist of a variety of different factors (e.g., unemployment, household income, race and ethnicity, etc.). Before incorporating or using the data below, we recommend visiting the social vulnerability section of the Planning and Policy page.
- USC's Social Vulnerability Index (SoVI) for N.C. Census Tracts (2010 Census Data)
- CDC's Social Vulnerability Index (SVI) for U.S. Census Tracts (2010 Census Data)

Coastal Fast Facts
Generating community support to explore and make tough decisions about investing in long-term resilience requires proof or evidence that the action will have a positive impact on the economy, environment and/or society. While being able to document and provide a detailed and inclusive cost-benefit analysis using local data is ideal, sometimes communities must rely on evidence or statistics that are based on work done regionally or nationally. The data summaries and associated infographics below can serve as reliable information that can back up the argument being made to take certain actions towards adaptation and resilience.
- NOAA Coastal County Snapshots: Access count-specific data about flood exposure (e.g., demographics, infrastructure, and environment within the flood zone), ocean jobs (e.g., the economic value of ocean-dependent jobs), and wetland benefits (e.g., contributions to safer, cleaner, and more economically productive communities).
- NOAA Coastal Fast Facts: View relevant national statistics and infographics for use in presentations or discussion to help make the case for investing in coastal resilience.
