FEMA’s National Risk Index rates natural-hazard risk for ID as Relatively Low (composite score 62.8), which is near the middle of the national distribution. The strongest component scores on US5 are flood (76.0) and wildfire (69.6). These scores are county-linked NRI values published for planning context — all ZIP codes in the same county share the same composite score on US5. Useful when comparing insurance and disaster exposure across areas, not a substitute for a parcel-level flood or fire determination.
Climate normals for ID show little to no average snow and around 44.3 inches of annual precipitation.
IRS migration statistics show a net inflow of about 8 for ZIP 83874 (ID) on US5’s published series — a signal of people/tax filers moving in relative to those leaving. Inflows often track job growth, housing demand, or lifestyle migration; treat the figure as a directional indicator rather than a precise headcount.
