What does New Haven County's hazard record show?
Reading the federal records together
FEMA's NFIP table contains a substantial paid-claim history for this county: 9,598 claims and $173.1M in payments. PlainHazard labels 500 or more claims a heavy registry record; that is a reporting bucket, not an official FEMA risk grade. The average paid claim was $18.0K. NFIP totals exclude uninsured flood losses and do not measure how many properties currently carry a policy.
The declaration register points in the busier direction. New Haven County's 36 federal records stand 18% above the Connecticut county mean of 30.5. That comparison describes how often federal action was recorded, including any Major Disaster, Emergency, and Fire Management entries shown on this page; it does not convert the count into future probability.
Declaration frequency
The FEMA register is busy by both local and national comparisons. It contains 36 entries for New Haven County, including 20 Major Disaster records, 18% above the Connecticut county mean. Across the 47-year span, that works out to 0.8 declarations a year. Hurricane leads the file with 11 entries. Declaration type records the federal action taken, not every assistance program approved.

What Hurricane declarations mean here
Hurricane is the most frequent declaration type on New Haven County's federal record, 31% of its declarations. Atlantic tropical systems run on a defined season, 1 June to 30 November, with most activity concentrated between August and October; Pacific and territorial basins run on their own calendars. A single named storm routinely produces one declaration number covering a long corridor of counties at once, well inland as well as on the coast, which is why an affected county's count can jump by several in one year without several separate events having occurred.
One practical distinction matters when reading these records: a tropical declaration usually bundles wind, storm surge and inland rainfall flooding under a single incident, but the insurance behind them is split. Wind damage falls to property insurers, while flood and surge damage is covered only under a separate National Flood Insurance Program policy. That is why a county can show heavy declaration activity and a comparatively small NFIP claims record, or the reverse.
Declaration counts describe past federal action. They are a record of what was declared, not a forecast of future hazard probability.
