Aitkin County, MN flood risk explained
Flood hazard in Aitkin County sits at the 69.4th national percentile, below the national norm for flood hazard; driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about once every 1 years. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Who actually carries the flood insurance FEMA requires
FEMA hasn't published a residential structure count for Aitkin County's mapped flood zone, so a reliable mandatory-compliance percentage can't be computed here — see the data quality guide for why this gap exists for roughly a quarter of US counties. Looking beyond the mandated zone, 0.5% of all residential structures in Aitkin County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
How Aitkin County compares nationally
Among the 3144 US counties FEMA scores for flood hazard, Aitkin County ranks 1003 — 1 being the highest hazard nationally — and 2014 by population among all 3144 counties covered here, where 1 is the largest. Aitkin County, Minnesota covers 1,821.317 square miles and counts roughly 16,335 residents.

Where Aitkin County's figures come from
Every figure on this page traces to a named FEMA dataset, documented in the methodology guide. Aitkin County's compliance figure is one of the ones affected by FEMA's incomplete denominator data — the data quality guide explains what that means and how many counties it touches.
