<p>Normalized 2020 and 2050 First Street flood risk data aggregated at the census-tract level. A lower number indicates less risk (0 is minimum) and a higher number indicates more risk (1 is maximum).

The overall mean is the national average of all census tracts.</p> <p>If you are interested in acquiring First Street flood data, you can request to access the data <a href="https://firststreet.org/data-access/paid-access/?utm_source=Census_Tract&amp;utm_medium=Purchase_Data&amp;utm_campaign=Zenodo#pricing-component">here</a>.
