FEMA’s National Risk Index rates natural-hazard risk for TN as Relatively Low (composite score 43.0), which is near the middle of the national distribution. The strongest component scores on US5 are hurricane (51.4) and flood (47.7). 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 TN show little to no average snow and around 61.8 inches of annual precipitation.
IRS migration statistics show a net inflow of about 7 for ZIP 38471 (TN) 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.
