2026 Flood Risk & Insurance Coverage Gap Analysis: The Southeast Exposure

Across Mississippi, Alabama, Louisiana, Florida, Tennessee, North Carolina and Georgia, only 8.2% of housing units carry a flood insurance policy — 2,460,830 National Flood Insurance Program policies covering 29,915,182 homes. That leaves 27,454,352 Southeast housing units with no flood coverage at all, or roughly 11 uninsured homes for every insured one. Meanwhile, the average NFIP claim paid in these seven states since 2016 was $66,431, while the average policy costs $1,199 a year. One average claim equals about 55 years of premium. This report, the eighth in Bridgeway Insurance’s original research series, measures that gap state by state using FEMA policy files, 325,159 individual NFIP claim records, and U.S. Census housing counts.

Executive Summary

Flood is the most common and most costly natural disaster in the United States, and it is also the peril most often left uninsured. Specifically, a standard homeowners policy excludes flood damage entirely, which means the only protection most Southeast homeowners have is a separate NFIP or private flood policy they must choose to buy. Bridgeway Insurance built this report to quantify how many households actually make that choice, and what it costs the ones who do not.

Importantly, the headline number is not a coastal story. Louisiana and Florida — the two states with genuine coastal exposure and widespread mandatory-purchase requirements — have coverage rates of 18.5% and 16.2% respectively. Every other state in the region sits below 3.5%. Tennessee, at 0.68%, has one NFIP policy for every 146 housing units, despite absorbing 16 flood-driven federal disaster declarations since fiscal year 2016.

Why the Gap Persists

Additionally, the gap is reinforced by a rule most homeowners misread. Federally backed lenders require flood insurance only inside a Special Flood Hazard Area. Consequently, homeowners outside those mapped zones interpret “not required” as “not at risk.” The claims data contradicts that reading directly. Across the seven states, 54,167 paid NFIP claims since 2016 came from properties rated in B, C or X zones — the low-to-moderate risk designations — and those claims drew $2.22 billion in payments.

Furthermore, the economics favor coverage more heavily than most households assume. In practice, the average NFIP policy in these seven states costs $1,199 a year including fees and surcharges, while the average claim paid since 2016 was $66,431. Notably, even in Mississippi, the state with the lowest average claim in the group at $24,972, a single claim covers more than 16 years of premium.

The Bridgeway Flood Coverage Gap Index (FCGI)

Specifically, Bridgeway created the Flood Coverage Gap Index to answer a question that raw policy counts cannot: where is the mismatch between flood risk and flood coverage widest? A state can look well covered simply because it is small, or look exposed simply because it is large. The FCGI normalizes for that.

The index runs from 0 to 100, where a higher score means a wider protection gap. It combines three weighted components, each drawn from a primary federal or Census source:

• Uncovered Housing Share (50% weight). The percentage of a state’s housing units with no NFIP policy in force. This is the core of the gap.
• Flood-Driven Disaster Frequency (25% weight). The count of FEMA major disaster declarations attributed to flood, hurricane, tropical storm, tropical depression, coastal storm or severe storm incidents from fiscal year 2016 through fiscal year 2026, scaled against the highest count in the group.
• Outside-Zone Claim Share (25% weight). The percentage of the state’s paid NFIP claims since 2016 that came from properties rated in B, C or X flood zones, scaled against the highest share in the group. This measures how much of the state’s realized flood loss happens where coverage is optional.

As a result, a state like Tennessee — low coverage, frequent flood declarations, and nearly a third of its claims falling outside mapped high-risk zones — scores near the top even though it has no coastline. Conversely, Florida scores lowest in the group despite having the most flood exposure in absolute terms, because its mandatory-purchase footprint has pushed coverage to 16.2% of housing units.

Source: Bridgeway Insurance analysis of FEMA NFIP policy data (July 31, 2026), OpenFEMA NFIP claims records (loss years 2016-2026), FEMA Disaster Declarations Summaries, and U.S. Census Bureau housing unit estimates (July 1, 2025).

Methodology and Data Sources

Because a research report is only as good as the data underneath it, every figure in this analysis traces to a named public dataset. Bridgeway pulled four sources on September 15, 2026 and joined them at the state level.

The Four Datasets

First, policy counts and premium totals come from FEMA’s NFIP Policy Information by State and Community file, snapshot dated July 31, 2026. FEMA reports Policies in Force and Total Annual Payment, where Total Annual Payment is written premium after discounts plus applicable fees, assessments and surcharges. Average annual payment is the state total divided by the state policy count.

Second, claims data comes from the OpenFEMA FIMA NFIP Redacted Claims dataset. Bridgeway queried every claim record with a loss year of 2016 or later in the seven states and summed amounts paid on building and contents claims. That pull returned 325,159 claim records totaling $21,600,740,843 in payments. Additionally, each record carries a rated flood zone, which is how the B, C and X zone analysis was produced.

Third, disaster counts come from FEMA’s Disaster Declarations Summaries. Bridgeway counted distinct major disaster declarations per state for fiscal years 2016 through 2026 and kept only water-driven incident types: flood, hurricane, tropical storm, tropical depression, coastal storm and severe storm.

Fourth, housing unit counts come from U.S. Census Bureau QuickFacts housing unit estimates as of July 1, 2025 (V2025 vintage).

Known Limits

Importantly, this analysis measures NFIP participation only. Private flood insurance policies are not captured in FEMA’s policy file, so true coverage rates are modestly higher than the figures shown — though private flood remains a small share of the residential market in most of these states. Furthermore, housing units include rental and seasonal properties, some of which carry coverage through a landlord or association policy rather than an individual one. Finally, claim payment totals reflect what the NFIP paid, not total flood damage sustained; uninsured losses by definition do not appear in any claims file.

Finding One: Coverage Collapses Away From the Coast

Specifically, the single clearest pattern in the data is the cliff between coastal-mandate states and everywhere else. Louisiana and Florida sit at 18.5% and 16.2% coverage. The remaining five states average roughly 2%.

State	NFIP Policies in Force	Housing Units	Coverage Rate	Uninsured Housing Units	Uninsured per Insured Home
Mississippi	47,956	1,369,536	3.50%	1,321,580	27.6:1
Alabama	44,519	2,406,306	1.85%	2,361,787	53.1:1
Louisiana	399,096	2,156,598	18.51%	1,757,502	4.4:1
Florida	1,748,473	10,789,047	16.21%	9,040,574	5.2:1
Tennessee	22,508	3,291,207	0.68%	3,268,699	145.2:1
North Carolina	128,772	5,168,052	2.49%	5,039,280	39.1:1
Georgia	69,506	4,734,436	1.47%	4,664,930	67.1:1
7-State Total	2,460,830	29,915,182	8.23%	27,454,352	11.2:1

Notably, Tennessee’s 145-to-1 ratio is the widest in the region and one of the widest in the country. The state has 3,291,207 housing units and 22,508 NFIP policies. Meanwhile, Tennessee absorbed 16 flood-driven federal disaster declarations between fiscal 2016 and fiscal 2026, including repeated severe-storm and flash-flood events in Middle and West Tennessee. For state-level detail, see our Tennessee flood insurance guide and the Tennessee flood insurance hub.

Finding Two: One in Six Paid Claims Came From a Low-Risk Zone

Furthermore, the most actionable number in this report is the share of claims paid on properties that were never required to buy coverage. Across the seven states, 54,167 of 325,159 paid claims since 2016 — 16.7% — were rated in B, C or X zones. Those claims drew $2,217,917,350 in NFIP payments.

State	Paid NFIP Claims Since 2016	Total Claims Paid	Claims in B/C/X Zones	Share of Claims Outside High-Risk Zones	Paid on B/C/X Claims
Mississippi	5,320	$132.9M	1,555	29.2%	$45.9M
Alabama	5,587	$180.3M	1,287	23.0%	$45.4M
Louisiana	71,398	$4.26B	20,051	28.1%	$1.00B
Florida	199,289	$15.41B	20,768	10.4%	$775.3M
Tennessee	3,896	$141.2M	1,237	31.8%	$37.5M
North Carolina	32,394	$1.28B	7,279	22.5%	$268.1M
Georgia	7,275	$190.8M	1,990	27.4%	$41.0M
7-State Total	325,159	$21.60B	54,167	16.7%	$2.22B

In particular, Tennessee (31.8%), Mississippi (29.2%) and Louisiana (28.1%) lead the region in outside-zone claim share. Because Florida’s mandatory-purchase footprint is so large, its outside-zone share is the lowest at 10.4% — but 20,768 Florida claims still came from B, C or X zones, more than any other state in the group in absolute terms. Additionally, our analysis of how FEMA’s Risk Rating changes affect flood premiums explains why zone designation and actual rating have drifted apart.

Finding Three: One Claim Equals Decades of Premium

Additionally, the cost argument against flood insurance weakens sharply once claim severity enters the picture. Across the seven states the average NFIP policy costs $1,199 a year and the average paid claim was $66,431. In practice, that means a single average claim returns about 55 years of premium.

State	Average Annual NFIP Payment	Average Claim Paid	Years of Premium Covered by One Claim	Average Claim in B/C/X Zones
Mississippi	$1,517	$24,972	16.5 years	$29,492
Alabama	$1,185	$32,264	27.2 years	$35,238
Louisiana	$1,292	$59,688	46.2 years	$50,113
Florida	$1,169	$77,349	66.1 years	$37,332
Tennessee	$1,553	$36,238	23.3 years	$30,313
North Carolina	$1,179	$39,490	33.5 years	$36,836
Georgia	$1,134	$26,224	23.1 years	$20,581
7-State Average	$1,199	$66,431	55.4 years	$40,946

Importantly, these averages are not evenly distributed. Florida’s average claim of $77,349 reflects hurricane-driven storm surge and high property values. Mississippi’s $24,972 average reflects a mix of coastal and inland riverine losses against a median home value of $169,800. Even so, no state in the region breaks below 16 years of premium recovered per average claim. For context on how claim settlement type changes what a homeowner actually receives, see our explainer on actual cash value versus replacement cost.

The FEMA Assistance Misconception

Notably, many homeowners assume federal disaster assistance will fill the gap. In practice, FEMA Individual Assistance grants average a few thousand dollars and are available only after a presidential major disaster declaration — and they are designed to make a home habitable, not to make an owner whole. FEMA’s own guidance notes that one inch of floodwater can produce roughly $25,000 in damage. Consequently, the gap between an average IA grant and an average NFIP claim payment in this region is on the order of $60,000.

Finding Four: Disaster Frequency Does Not Track Coverage

Furthermore, if flood coverage followed flood experience, Mississippi and Tennessee would be among the best-covered states in the country. Mississippi recorded 20 water-driven federal major disaster declarations between fiscal 2016 and fiscal 2026 — the highest count in the region — while covering 3.5% of its housing units. Tennessee recorded 16 while covering 0.68%.

Conversely, Georgia and North Carolina recorded 11 and 12 respectively, and both sit under 2.5% coverage. As a result, the region’s coverage pattern is explained far better by lender mandates and mapped zone boundaries than by lived flood experience. Our analysis of why flood premiums are rising across the Southeast covers the rating-side half of this story.

The September 30, 2026 NFIP Deadline

Because timing matters this year, one date belongs in every Southeast homeowner’s calendar. The National Flood Insurance Program’s current authorization expires at 11:59 p.m. on September 30, 2026. FEMA’s congressional reauthorization page explains what a lapse does and does not affect.

What a Lapse Would and Would Not Do

Specifically, a lapse would suspend the NFIP’s authority to write new policies and to issue increased coverage on existing ones. Importantly, policies already in force would remain in force through the end of their one-year term, and FEMA would continue paying valid claims as long as funds are available. Additionally, a lapse typically stalls real estate closings that require flood insurance as a condition of a federally backed mortgage.

In practice, the takeaway for homeowners is simple: a policy bound before the deadline is not at risk, while a policy application sitting unfinished on the deadline is. Furthermore, standard NFIP policies carry a 30-day waiting period before coverage takes effect, which means waiting for a storm in the forecast is never a workable strategy. Our 2026-2027 Southeast seasonal outlook covers what the coming months look like.

State-by-State Deep Dives

Because each state’s gap has a different shape, the sections below break the index down by market. Specifically, each entry pairs the state’s FCGI rank with the coverage, claims and disaster figures that produced it.

Mississippi — FCGI 96.3 (Rank 1 of 7)

Under Mississippi conditions, the gap is driven by inland exposure rather than the Gulf Coast alone. Mississippi carries 47,956 NFIP policies against 1,369,536 housing units, a 3.50% coverage rate, and it recorded 20 water-driven federal major disaster declarations between fiscal 2016 and fiscal 2026 — the most in the region. Notably, 29.2% of the state’s 5,320 paid claims since 2016 came from B, C or X zones, and those outside-zone claims averaged $29,492. Additionally, with a median home value of $169,800, a single average Mississippi claim of $24,972 represents roughly 15% of a typical home’s value and about 16.5 years of premium.

Tennessee — FCGI 94.7 (Rank 2 of 7)

Specifically, Tennessee has the thinnest flood coverage in the region and one of the thinnest in the nation: 22,508 policies against 3,291,207 housing units, or 0.68%. Furthermore, the state pays the highest average annual NFIP payment in the group at $1,553, which reflects a policy base concentrated in genuinely high-risk riverine locations. Importantly, 31.8% of Tennessee’s paid claims since 2016 came from low-to-moderate risk zones — the highest outside-zone share of any state studied. As a result, Tennessee homeowners who assume an unmapped address means no exposure are working from the weakest evidence in the region.

Further reading for Tennessee: our Tennessee flood insurance guide, the Tennessee flood insurance hub, and our Tennessee hurricane insurance guide.

Alabama — FCGI 84.7 (Rank 3 of 7)

In practice, Alabama splits into two very different flood markets. Coastal Baldwin and Mobile counties carry mandatory-purchase requirements, while the rest of the state largely does not. Statewide the result is 44,519 policies against 2,406,306 housing units, a 1.85% coverage rate, alongside 14 water-driven disaster declarations since fiscal 2016. Additionally, Alabama’s average annual NFIP payment of $1,185 is among the lowest in the region, while its average claim of $32,264 recovers about 27 years of premium. Notably, the 1,287 claims paid in B, C or X zones averaged $35,238 — higher than the state’s all-zone average.

Further reading for Alabama: our Alabama flood insurance guide, the Alabama flood insurance hub, and our Alabama hurricane insurance guide.

Georgia — FCGI 84.6 (Rank 4 of 7)

Because Georgia’s population and housing stock have grown quickly, its coverage gap has grown with them. The state holds 69,506 policies against 4,734,436 housing units — a 1.47% coverage rate and 4,664,930 uninsured units, the second-largest raw gap in the region. Furthermore, 27.4% of Georgia’s 7,275 paid claims since 2016 came from outside mapped high-risk zones. In particular, Georgia’s average outside-zone claim of $20,581 is the lowest in the group, which suggests a pattern of frequent moderate losses rather than rare catastrophic ones — exactly the profile a modest-limit policy handles well.

Further reading for Georgia: our Georgia flood insurance guide, the Georgia flood insurance hub, and our Georgia hurricane insurance guide.

North Carolina — FCGI 81.4 (Rank 5 of 7)

Under North Carolina conditions, hurricane-driven inland flooding dominates the loss record. The state carries 128,772 policies against 5,168,052 housing units, a 2.49% coverage rate, and it has paid out $1.28 billion on 32,394 claims since 2016 — the third-highest total in the region. Importantly, 22.5% of those claims came from B, C or X zones, and they averaged $36,836. Additionally, North Carolina’s average claim of $39,490 against an average annual payment of $1,179 means one claim recovers roughly 33.5 years of premium.

Further reading for North Carolina: our North Carolina flood insurance guide, the North Carolina flood insurance hub, and our North Carolina hurricane insurance guide.

Louisiana — FCGI 79.1 (Rank 6 of 7)

Notably, Louisiana is the best-covered state in the region at 18.51%, with 399,096 policies against 2,156,598 housing units — and it still carries 1,757,502 uninsured units. Furthermore, Louisiana has paid $4.26 billion on 71,398 claims since 2016, and 28.1% of those claims came from B, C or X zones, drawing more than $1.00 billion in payments. In practice, that billion dollars is the clearest single illustration in this report that mapped zone boundaries do not describe where flood losses actually occur. Additionally, the state’s average outside-zone claim of $50,113 is the highest in the group.

Further reading for Louisiana: our Louisiana flood insurance guide, the Louisiana flood insurance hub, and our Louisiana hurricane insurance guide.

Florida — FCGI 71.4 (Rank 7 of 7)

Specifically, Florida scores lowest on the index because mandatory-purchase requirements have pushed coverage to 16.21% — but the state still has 9,040,574 uninsured housing units, by far the largest raw gap in the region. Furthermore, Florida has paid $15.41 billion on 199,289 claims since 2016, and its average claim of $77,349 is the highest in the group, equal to about 66 years of premium at the state’s $1,169 average annual payment. Importantly, 20,768 Florida claims came from B, C or X zones despite those zones representing only 10.4% of the state’s claim count.

What Southeast Homeowners Should Do With This Data

Because the gap is a decision problem rather than an information problem, the action steps below are ordered by how much they change a household’s exposure per dollar spent.

1. Check your rated flood zone, then ignore what it implies about need. Specifically, 16.7% of paid claims in this region since 2016 came from B, C and X zones. A low-risk designation lowers your premium; it does not lower your loss.
2. Price a preferred-risk policy before assuming you cannot afford one. In practice, low-to-moderate risk properties often rate far below the state averages shown above, because those averages are pulled upward by high-risk coastal policies.
3. Bind before September 30, 2026 if you are on the fence. Additionally, remember the standard 30-day waiting period — a policy bound on September 29 does not take effect until late October.
4. Add contents coverage, not just building coverage. Notably, NFIP building and contents are separate purchases, and contents-only losses are common in finished basements and ground-floor units.
5. Review limits against replacement cost, not market value. Furthermore, NFIP building coverage caps at $250,000 for residential structures; excess flood coverage fills the gap above that.
6. Ask about private flood options. Because private carriers rate differently, they sometimes beat NFIP pricing on well-elevated, low-to-moderate risk homes.

Frequently Asked Questions About the Southeast Flood Coverage Gap

What percentage of Southeast homes have flood insurance in 2026? Across Mississippi, Alabama, Louisiana, Florida, Tennessee, North Carolina and Georgia, 8.23% of housing units carry an NFIP flood insurance policy as of the July 31, 2026 FEMA snapshot — 2,460,830 policies against 29,915,182 housing units. Coverage ranges from 18.51% in Louisiana down to 0.68% in Tennessee. Private flood policies are not included in FEMA’s count, so true coverage is modestly higher.

Does homeowners insurance cover flood damage? No. A standard homeowners policy excludes damage from surface water, rising water, storm surge and overflow of a body of water. Flood coverage must be purchased separately, either through the National Flood Insurance Program or a private flood carrier. That exclusion is the single most common coverage surprise Bridgeway sees after a storm, and it applies in all seven states covered by this report.

How many flood claims come from outside high-risk flood zones? In these seven states, 54,167 of 325,159 paid NFIP claims with loss years of 2016 or later — 16.7% — came from properties rated in B, C or X zones, the low-to-moderate risk designations where coverage is not federally required. Those claims drew $2.22 billion in payments. Tennessee had the highest share at 31.8%, followed by Mississippi at 29.2% and Louisiana at 28.1%.

How much does flood insurance cost in the Southeast? The average annual NFIP payment across the seven states is $1,199, including premium after discounts plus fees, assessments and surcharges. State averages range from $1,134 in Georgia to $1,553 in Tennessee. Importantly, these are averages across all policies in force, including high-risk coastal properties; a preferred-risk policy on a low-to-moderate risk home typically prices well below the state average.

Coverage, Claims and Timing Questions

What is the Bridgeway Flood Coverage Gap Index? The FCGI is an original 0-100 metric created by Bridgeway Insurance that measures the mismatch between flood risk and flood coverage in a state. It weights the uncovered share of housing units at 50%, flood-driven federal disaster declarations from fiscal 2016 through fiscal 2026 at 25%, and the share of paid claims occurring in B, C or X zones at 25%. Higher scores mean wider gaps. Mississippi scores 96.3 and Florida scores 71.4.

What happens if the NFIP is not reauthorized by September 30, 2026? If Congress does not act, the program loses authority to write new policies or increase coverage on existing ones. Policies already in force continue through the end of their one-year term, and FEMA continues paying valid claims as funds allow. Additionally, a lapse typically delays real estate closings that require flood insurance for a federally backed mortgage. Binding coverage before the deadline avoids the issue entirely.

How long does it take for flood insurance to take effect? Standard NFIP policies carry a 30-day waiting period from the date of purchase. Limited exceptions exist, including policies purchased in connection with a loan closing and certain post-wildfire situations. Because of that waiting period, flood coverage cannot be bought in response to a storm already in the forecast — the decision has to be made well ahead of the event.
