A genuine, three-way disagreement -- not just in level, but in direction

BestPlaces cites a cost-of-living index of 85.8, meaning total costs run 14.2% BELOW the national average. AreaVibes instead cites 119, meaning costs run 19% ABOVE the national average. A third source, America's Dashboard, cites 92.4 -- below the national average but on a different scale than BestPlaces. This is disclosed as a real, unreconciled discrepancy rather than resolved to one number -- BestPlaces and AreaVibes don't just differ in magnitude, they disagree on whether Collierville is cheaper or more expensive than the national average.

A real, growing median household income

Collierville's median household income grew to $138,598 in 2024, up from $134,319 the prior year -- a real, sourced increase, unlike the essentially flat income figure documented for Farragut elsewhere in this same-session batch.

No state income tax, offset by Shelby County's high combined sales tax

Tennessee levies no tax on wages or salaries. Shelby County's combined sales tax is cited at 9.75% (7.0% state + 2.75% county) -- higher than the 9.25% cited for Knox County (Farragut) elsewhere in this same-session batch, and among the higher combined rates in the nation.
