Expected yearly hurricane loss
The damage hurricanes are expected to do to buildings in an average year, in dollars for every $100,000 that the buildings are worth. FEMA works it out from how often hurricanes have struck since 1851 (1949 in the Pacific) and how much damage they did. Where FEMA says hurricanes cannot reach, it is 0.

Where it comes from
FEMA National Risk Index · FEMA National Risk Index v1.20, NRI_Table_Counties / NRI_Table_States, HRCN_ALRB
Expected yearly damage to buildings from hurricanes; 0 where FEMA says hurricanes cannot reach. A rate over the area's building value. FEMA publishes it for counties and states; it is not rebuilt for other areas here.
Combining areas: it cannot be combined, so it is shown only where its publisher works it out.
What it goes with
The strongest links that have a page of their own. Unadjusted is the link before adjusting for anything, from −1 (opposite) to +1 (in step). Adjusted compares places with the same population density, income and education levels, so those differences can’t explain the link. This list leaves out the 2 pairs built from the same numbers or the same model as this measure, since they are bound to match.
| Measure | Unadjusted | Adjusted |
|---|---|---|
| Expected yearly hurricane loss and Winter nightly lowWhere Expected yearly hurricane loss is higher, Winter nightly low tends to be higher: a weak link that holds when only places with similar density, income and education are compared, and inside states as well. Winter nightly low by US county | +0.40 | +0.38 |
| Expected yearly hurricane loss and Cooling degree daysWhere Expected yearly hurricane loss is higher, Cooling degree days tends to be higher: a weak link that holds when only places with similar density, income and education are compared, and inside states as well. Cooling degree days by US county | +0.40 | +0.38 |
| Expected yearly hurricane loss and Average temperatureWhere Expected yearly hurricane loss is higher, Average temperature tends to be higher: a weak link that holds when only places with similar density, income and education are compared, and inside states as well.

| Expected yearly hurricane loss and Winter daily sunlightWhere Expected yearly hurricane loss is higher, Winter daily sunlight tends to be higher: a weak link that holds when only places with similar density, income and education are compared, and inside states as well. Winter daily sunlight by US county | +0.32 | +0.32 |
| Expected yearly hurricane loss and Water areaWhere Expected yearly hurricane loss is higher, Water area tends to be higher: a weak link that holds when only places with similar density, income and education are compared, and inside states as well. Water area by US county | +0.31 | +0.31 |
Population makeup
How this measure varies with the racial and ethnic makeup of counties. Every group is shown, whatever its rank. These are links across counties: they describe places, not people. They say nothing about any person’s risk or behaviour based on their race. Counties with a larger share of one group also differ in much else, such as income, segregation, region and history. The adjusted figure only accounts for density, income and education.
| Share of residents | Unadjusted | Adjusted |

| Expected yearly hurricane loss and Share White, not HispanicWhere Expected yearly hurricane loss is higher, Share White, not Hispanic tends to be lower: a weak link that holds when only places with similar density, income and education are compared. Share White, not Hispanic by US county | -0.19 | -0.16 |
| Expected yearly hurricane loss and Share Black, not HispanicWhere Expected yearly hurricane loss is higher, Share Black, not Hispanic tends to be higher: a weak link that holds when only places with similar density, income and education are compared. Share Black, not Hispanic by US county | +0.23 | +0.20 |
| Expected yearly hurricane loss and Share Hispanic or Latino, any raceCould easily be chance once only places with similar density, income and education are compared. Share Hispanic or Latino, any race by US county | +0.02 | +0.04 |
| Expected yearly hurricane loss and Share Asian, not HispanicCould easily be chance once only places with similar density, income and education are compared. Share Asian, not Hispanic by US county | -0.03 | -0.04 |

Highest and lowest
Of 3,144 counties reporting it. These are the two ends of a national ranking. For most measures, that ranking mostly sorts places by income and how urban they are. That is why the place pages compare each place with similar places instead.
Highest
- Hyde County, NC — 621
- Carteret County, NC — 537
- Pamlico County, NC — 488
- Onslow County, NC — 465
- Tyrrell County, NC — 461
Lowest
The middle area reports 0.166. The middle half of counties falls between 0 and 3.57 (the 25th to 75th percentile).
