Mô tả

This dataset provides information on structures that have had multiple National Flood Insurance (NFIP) claims across the history of the program. The data contains NFIP-insured structures that fall within the four categories of Repetitive Loss and Severe Repetitive Loss that FEMA tracks. Definitions of these categories are provided in the field descriptions. There are also fields to show whether a structure is currently NFIP-insured, has been mitigated, and other characteristics. The data includes properties that have since been mitigated or demolished and may no longer considered to be in any of the listed categories.

Location information has been redacted to protect personal privacy. Location information is derived from reported address, geocoding of that address, and reported NFIP community. Because NFIP insurance claims data spans the history of the NFIP, many of the structures have poor address information resulting in poor or missing coordinates and additional location fields that rely on those coordinates. An effort has been made to fill in missing data and resolve conflicts between state, county, community, and census block group. Because of this effort, statistics derived from this data may differ from those reported elsewhere by FEMA or others.

There is a lot of interest in this data as it touches many program areas of the NFIP and serves as an indicator of flood risk and mitigation need.

text
FIPS five-digit numeric code used to idenify counties and county equivalents in the United States, the District of Columbia, US territories, outlying areas of the US and freely associated states.

state State
text
The name or phrase describing the U.S. state, district, or territory. yes
stateAbbreviation State Abbreviation
text
Two letter abbreviation of the state (e.g., VA). Generally derived from the property address but geocoded location may be used in some cases. yes

In both instances, at least two of the claims must be within 10 years of each other, and claims made within 10 days of each other will be counted as one claim. Yes is indicated with either a 'true' or '1'. No is indicated with either a 'false' or '0'. When mitigated, this value may change from true to false. yes

Yes is indicated with either a 'true' or '1'. No is indicated with either a 'false' or '0'. yes
