Final answer:
Approximately 23,000 communities currently participate in the NFIP, which is administered by FEMA in the United States.
Step-by-step explanation:
As of August 2021, there are approximately 23,000 communities that currently participate in the National Flood Insurance Program (NFIP). This program is administered by the Federal Emergency Management Agency (FEMA) in the United States.
The NFIP aims to provide affordable flood insurance to property owners and promote floodplain management to reduce the risk of flooding. By participating in the NFIP, communities gain access to flood insurance policies offered by the program and can benefit from floodplain regulations and flood mitigation efforts.
Community participation in the NFIP is voluntary, but it is encouraged to ensure that residents have access to flood insurance coverage and to promote responsible development in areas prone to flooding.
