Middle half: the middle half of premiums on single-family NFIP policies that took effect Sep 2025–Sep 2026, by the flood zone each policy is rated in. It is what insured homes here pay, not a quote for any one building.
Full-risk median: the median of FEMA's own full-risk premium for the same policies (Risk Rating 2.0). A discounted policy rises toward it a step each year, within the law's cap on yearly increases.
